              dr r pearl pearl to talk on longevity johns hopkins professor to speak to sigma xi on modern medicine explaining the importance of mi croscopic examination as an aid to chemical analysis dr clyde w mason professor of inorganic chem istry at cornell university lectured on chemical microscopy to the members and friends of the chemi cal society thursday evening the speaker illustrated his lecture with lantern slides since certain chemical problems do not yield readily to tests for spe cific reactions dr mason explained that the chemist has helped indus try with this newly developed in strument the high-powered micro scope one large drug company engaged in the manufacture of rubber tub ing discovered that their product was being sold perforated with holes having appealed to a chemist from cornell the manufacturers soon found out that the cause of the difficulty was grains of quartz imbedded in the rubber upon investigation the company learned that one of their janitors had swept some debris into the mix ture the janitor had figured that which have been set at lehigh for so long he feels very sure that the new type organization will function much more efficiently than the old with all due respect to those men who served on the athletic commit tee long and well he says the committee form of government is not efficient capable of rapid action or rapid judgment when necessary and in many cases the policy of a committee is a matter of compro mise between the various elements of the committee he adds that the coaching staff as built up un der the old organization was more or less a system of accretions with many of the men on part time only in the new organization he says an attempt has been made to put all possible men on full time and reorganize their duties so that they may function more efficiently an athletic department should be made up as far as possible of men who are devoting their lives to athletic work and not of men whose primary interest is elsewhere and with whom coaching is only a sideline eshbach tells of telephony mining society hears gillson lehigh alumnus explains to electricals how short wave station was bui extraction of ilmenite de posits in all parts of world is described almost anything in the factory could be used in the manufacture of rubber and acted accordingly dr mason said that a course in chemical microscopy is compulsory at cornell for all chemical engin eers and chemistry majors the advantage of the microscope stated the cornell professor lies in the fact that the instrument enables the chemist to use minute samples of the compound to determine its composition without the use of a magnifying instrument several an alyses would be impossible because certain substances have the same chemical composition optically similar compounds dif fer widely and it is because of the microscope that the chemist is able to analyze minute objects in the field of organic chemistry the microscope has played an im portant part since chemistry not only deals with the composition of matter but also its behavior the microscope has enabled the chem ist to study the activity of small particles when in solution certain precipitates although too small to be passed through a sieve said the speaker may be observed under a high-powered microscope and their characteristic reactions de termined for use in comparisons dr ma son showed the audience a picture of a microscope with a single eye piece and two fields of vision the unknown is placed under one part of the microscope and the known beneath the other the observer looking through the single eye-piece may then watch the reaction with out changing his position to pay dues the lecture was preceded by a short business meeting of the so ciety the president milton meiss ner 34 urged the students to pay their dues since open house is coming soon meissner asked the members to report any stunts or ex hibitions they may have to dr bil linger who will pass on their accep tability pointing out the fact that the chemical society has never had its picture in the epitome meissner asked the members for an expres sion of opinion about the advisa bility of having a picture taken this year r n lindabury president of the lehigh union and a member of the society told the students that the chemical society is the oldest course society on the campus and that it would be beneficial from the standpoint of publicity to have a page in the epitome devoted to the society debaters to oppose t wo teams tonight the effect of alcohol modern surgery preventive medicine and serums and the advance in treat ment of children's diseases will be the subject matter of a lecture to night on human longevity by dr raymond pearl professor of bi ology at johns hopkins university the lecture will be given at 8 o'clock in packard auditorium un der the sponsorship of sigma xi national research society just previous to the lecture the speaker will be guest of honor at a banquet to be held at the hotel bethlehem pioneer in biometry dr pearl is one of the pioneers in the field of biometry a branch of biology which applies statistical methods to biological problems his investigations of the various factors which affect human life have been of the greatest values to the insurance companies and the na tional health bureau his chief stu dies have been concerning the ef fect of medical science upon the population of the country as a whole rather than its application to the individual upon the length of human life and upon • population problems dr pearl is a member of phi kappa psi phi beta kappa phi kappa phi a corresponding mem ber of the academy of natural sci ences and many other honorary so cieties he was formerly president of the international union for scientific investigation of population prob lems and has several rewards of merit from foreign governments during the world war he was chief of the statistical division of the united states food administration pi mu epsilon hears george and beatty fort and shook appointed to secure next speaker courses for coaches may be of fered at lehigh in the near future nelson a kellogg director of ath letics makes this announcement in the february alumni bulletin he says further that alumni co operation is essential for success in intercollegiate athletics this means that the alumni should do all they can to send to lehigh students with brain brawn and enough money the purity policy in athletics which lehigh has maintained and which other colleges are tending to adopt will be continued mr kel logg says definite plans are already under way to set up courses as electives in the college of liberal arts as well as business administration which will prepare lehigh alumni who so desire to act as coaches in high schools and academies one of the weaknesses in the past has been that very few alumni were in edu cational work and consequently other colleges have had more men acting as feeders to their athletic teams on account of their positions in schools than lehigh has had while lehigh will never turn out as many teachers as some institu tions do every man counts has definite plan the alumni can rest assured that the administration of the depart ment has a definite plan and is working toward a definite goal but must have continuous aid from the alumni in order to reach it now as to material proper says mr kellogg there are throughout the area from which lehigh natur ally draws many good athletes with mental ability to meet lehigh stan dards and with money enough to come to lehigh it is upon such prospects that the alumni interested in the future of lehigh athletics and especially football should con centrate and this work should be gin at once as men entering lehigh in 1934 under the rules will not be available until 1935 this work of course can be urged and directed from the central office he says decisively but the actual work in the field must be done by alumni who desire to im prove the athletic situation here unless a certain number of the alumni are willing to undertake this work no amount of good coaching and management can raise lehigh teams above a certain level alumni backing needed one thing is sure he continues that in the present days of compe tition between colleges in athletics the only college which can be suc cessful is the one which has full and complete co-operation of its alumni with the athletic program and also their enthusiastic support in connection with athletic schol arships the director says that there is no doubt but that the purity policy which has been in effect is here to stay not only at lehigh but it is being adopted widely in this section by other colleges the ac tion of the middle atlantic associa tion of colleges and secondary schools and the recent action of the presidents of the pennsylvania colleges in the form of an associa tion on adopting rules all are tend ing to promote among the other colleges of the state the standards i would not be surprised to see a suspension bridge of 5,000 feet be ing built within the next few years stated sterling johnston engineer of the mcclintic-marshall company last evening in a lecture to the american society of civil engin eers in packard laboratory the topic of the lecture was sus pension bridge cables mr john ston used a seven foot model sus pension bridge as an aid in explain ing the various features of the bridge he said that the two types of bridges that are being built are the cantilever and the suspension the quebec bridge which is 1,800 feet long is an example of the cantilever type the george washington bridge which is 3,500 feet is the largest suspension bridge in the world however the golden gate bridge in california will be 4,500 feet in length mr johnston also said that it wasn't until the last 20 years that any confidence was placed in suspension bridges four principals used the four principal parts of sus pension bridges are the cables tow ers anchorage and floors early failures of this type of bridge were due to poor anchorage the engin eers on the golden gate bridge are using two anchors on the bridge each with a pull of 30,000 tons claims the lecturer mr johnston then said that sus pension bridges were being built bjj the chinese 400 years ago the cables for these bridges were made from woven bamboo the first sus pension bridge in america was built by james finley in 1801 fin ley was also the father of the stif fening truss the elastic theory which de manded that the cables retain their parabolic shape was then suggest ed this theory was abandoned about ten years ago in favor of the deflection theory the speaker as serted french engineers have been us ing diagonal braces thus eliminat ing the necessity of using stiffening trusses the brooklyn bridge was built on the french system he added first bridge in 1929 mr johnston also said that the first real beginning in the building of suspension bridges was made in 1909 with the building of the man hattan bridge the deflection the ory was used in this bridge the deflection theory takes into account the dead load of the bridge itself mr johnston then read an extract from the journal of the franklin institute of 1925 which dealt with the deflection theory the george washington bridge has no stiffening trusses because it de pends on dead load alone for rig idness following the lecture by mr johnston a nominating committee was appointed to select candidates for the offices for the coming year elections of these officers will be held soon the nominating commit tee is composed of the present offi cers of the local group of american society of civil engineers sugges tions from other members will be welcomed by the committee union to plan constitution in arcadia room tonight general plans for a safe ethical and dignified open house " pro gram were formulated and sub-com mittees appointed at the first meet ing of the open house commit tee tuesday principal points in the revised program considered by the commit tee for this year include an elimin ation of crowding at main points of attraction and special development of all new ideas on the part of stu dents in a recent interview prof f v larkin head of the mechanical en gineering department and chairman of the open house committee declared that " open house should be an opportunity to stimulate both the students and faculty and ex pressed the hope that the occasion will give every student an oppor tunity to work on any project he may desire even if it be in a de partment other than his own thomas to investigate a new feature of the program was indicated in the appointment of dr h p thomas head of the depart ment of education to investigate possible exhibits to commemorate the one hundredth anniversary of free public education in pennsylva nia dr thomas will attend several educational conventions with that point in view the crowding characteristic of last year's open house will be eliminated so far as possible by the intermittent direction of visitors through the exihbitions professor larkin explains in this manner spectators will not be caused the inconvenience of doubling back on features they have already seen in general however he characterized the plans for the coming exhibition as being essentially like those which were successful in the past year the open house committee in addition to professor larkin in cludes president c r richards a e buchanan alumni secretary and the heads of all the departments of the university the sub-committees and their chairmen are named as follows publicity a e buchanan welcom ing maj j o green jr and parking a w litzenberger super intendent of buildings and grounds open house will be held this year on april 20 and 21 the latter day has been officially set aside as sub-freshman day and exhibits at this time will give the prospec tive students an unusual opportun ity to view lehigh's facilities last exhibit successful the exhibit given during the past year was lehigh's first attempt at the presentation of an open house and results were hailed as successful by university officials at that time about 20,000 persons visited the various displays on the two days of presentation almost ever r department of the university operated exhibits from early morn ing to late night the plan of the open house programs is not a new one massa chusetts institute of technology having celebrated a decade in this type of work brooklyn polytech nic institute temple university lafayette college and yale univer sity arc working on exhibits similar to this at the present time papers to be read how the lawrenceville n j short wave station was built and how it transmits trans-oceanic tele phone calls was explained by o e eshbach 15 of the trans-atlantic short wave station at lawrence ville at a meeting of the electrical engineering society last evening richard m byers 34 first pre sented a paper on insulator test ing with a thousand volts he ex plained the several tests which com mercial high tension line insulators undergo before being shipped from the factory these includes tests on tensiles strength electrical proper ties and hardness he stated furth er that insulators may take up one third of the cost of a transmission line byers illustrated his talk by the projection of snap shots that he took in connection with research work on this subject he said that there is a tendency to use glass in sulators as they are cheaper to pro duce mr eshbach opened his talk by describing the operation of the main control system in the american tel ephone and telegraph building in new york city many years were spent in research before the trans mitting station at lawrenceville was built he described the three short wave channels to europe and the one to south america this station is able to transmit to london and then the waves are sent practically around the world by means of slides mr eshbach explained the process of a call from a new york telephone to london by the way of short wave through the lawrenceville station the antenna towers at lawrence ville are 180 feet high there are two groups of towers one of eight and the other of nineteen masts the wires for transmitting are so arranged that the waves are easily directed to europe or south amer ica he asserted there is a unique system used for safety of employees a system of electromagnetic locks and keys so arranged that one has to have the proper ke r s which shut off power before he can enter the dangerous enclosure mr eshbach taught for six years in the electrical engineering depart ment after his graduation taj beta pi will entertain prospective pledgees at smoker a smoker for prospective tau beta pi men and a faculty dinner were planned at the meeting of the lehigh chapter last friday the committee chosen to arrange for the faculty dinner is as follows w.r.taylor c.e.'34 chairman h.m strub ch e 34 and e h en gel met e 34 both these affairs will be given soon states e l wildman president the smoker will be for men eligible for pledg ing this spring and the dinner for all tau beta pi men and the fac ulty a s m e to meet tonight in wilkes-barre development of exploitation of ilmenite deposits in far-off corners of the world were described by dr joseph l gillson at the meeting of the mining and geological society last night dr gillson was sent by the e i dupont de nemours company to lo cate deposits of the mineral after the company had bought patent rights for the treatment of ilmenite to extract the titanium dioxide titanium dioxide he said is used in paints because its high index of refraction makes it valuable for such use ilmenite contains about 50 per cent of the paint ingredient but occurs in workable deposits in few localities , if all the ilmenite distributed along the atlantic seaboard occur red in one deposit he continued it would make an enormous supply of the mineral one deposit in flor ida is being worked however workable sources of ilmenite are located on the west coast of africa in new zealand in california on an island near tasmania and in in dia dr gillson's job was to report on the deposit at the southern tip of india found on beaches there as in the other deposits the mineral occurs in black beach sands associated with numerous other minerals carried by streams from inland igneous rocks the heavier minerals are deposited on the beaches and the lighter elements are borne out to sea he said the english company operating the deposit reported an inexhaus tible supply of the valuable mineral however dr gillson came to the conclusion that the supply was fixed the sea taking away and re depositing the mineral upon the beach the valuable sands extend for a mile along the indian coast on the arabian sea dr gillson stated that the supply will satisfy world de mand for many years to come in working the deposit native la bor is employed boys carry the ore in baskets to bullock carts which haul it to a cencentrating plant four miles away there magnetic separating gravity concentration tabling and screening are used to get a concentrate dr gillson de scribed the process as inefficient and impractical the concentrated ore is loaded on steamships which carry it back to the states for the extraction of the titanium dioxide the speaker said that the sands are interesting from the point of ore dressing research since 20 minerals are present with the titaniferous constituent thomas attends meet this week-end prof h p tho mas of the department of education will leave for cleveland to attend a meeting of the national voca tional guidance association of which he is a program adviser the members of the lehigh union will meet tonight in the arcadia room drown hall at 7:30 to discuss details for a constitution a plan for the semester's work also will be made out in 1927 when the lehigh un ion was formed it was agreed upon by those representing the school to acquire first a knowl edge of what was needed before forming the constitution since the union has been operating for seven years it now has gained sufficient information with which to draw up a constitution worthy of the organization which it represents r n lindabury president states this will be a business meet ing and only matters pertaining to business will be discussed two papers showing the new de velopments in the uses of alloys of steel and iron and reviewing the results on a long series of experi ments in the use of many types of materials in connection with the mining and preparation of anthra cite coal will be read at 6:30 tonight at the meeting of the anthracite lehigh valley section of the a s m e

wednes day evening in packard laboratory prior to the'talks a petition for admission to the fraternity was made by members of the mathemat ical club of the university of geor gia this petition was accepted by the local chapter d c bomberger e e 34 pres ident of the society appointed a committee consisting of prof tom linson fort head of the department of mathematics and c a shook assistant professor of mathematics to select a speaker for a meeting which will be open to the public the first talk was given by h p george ch e 35 who spoke on stereographic projections george explained the celestial sphere and showed several facts by means of figures which he drew on the board k o beatty jr ch.e 35 spoke on the mathematical investiga tion of the scattering of the beta rays in giving a short history of the beta rays beatty stated that the multiple scattering rays theory worked best for the beta rays and that the single scatter ing theory worked best for the alpha rays lehigh to
