              the regular meeting of the mathematical club was held in the physical laboratory on tuesday night mr underwood 97 read a paper on " singular solutions of differential equations to resolve a differential equation consists in finding a relation between variables and constants this rela tion is called a primitive and the differential equation can be deduced from it either by differentiation or elimination of constants a singu lar solution is a solution of a differ ential equation which does not in clude the arbitrary constant c the expression which vanishes when two roots of a differential equation are equal is called the discriminant and the method of finding it is to differentiate the primitive with re spect to c and then eliminate c between the resultant and the origi nal equation the speaker then gave the conditions necessary to render a singular solution and also the exceptions there can be no singular solution to an equation of the first degree and first order for 0 will disappear when we differ entiate the speaker gave an ex ample of an equation the singular solution being a circle while the primitive was a series of lines tangent to the circle he stated the theory and showed that the primitive was not always necessary in singular solutions but it may be determined from the differential equation in concluding his paper mr underwood made numerous appli cations of the theory of singular solutions the paper showed that the speaker had studied his subject carefully and all the various points were made clear the paper was accepted by the club and mr un derwood elected to membership mr hess announced that mr mora 96 would probably read at the next meeting a paper on the universal integrator the ma chine has been used by professor klein in making difficult integra tions mr mora has spent consid erable time on the subject having translated it from the french it will doubtless prove interesting to all on motion the meeting ad journed dancing class the last dancing class of the series of three that have been ar ranged this winter by a committee of college men was held last tues day evening at the eagle hotel it was in all respects a most en joyable dance being larger than either of the two that preceded it dancing began at 9 o'clock and with a short intermission for sup per at 12 o'clock lasted until half past two the music was furnish ed by euhe's allentown orchestra the committee to whose ef forts the success of the three dan ces is due is composed as follows : h w baldwin 96 w c dick erman 96 c v ferriday 96 v a johnson 96 c f scott 97 and e c thurston 96 committee on sports at the last meeting of the com mittee on sports the question of sending a team to represent lehigh in the relay races which are to occur in philadelphia during april was fully discussed the race is a quadruple one including besides lehigh cornell columbia and lafayette the committee finally decided to accept the invita tion of the university of pennsyl vania provisionally and to imme diately start the best men in training for the event it is a good opportunity for lehigh to show what she can do in that line of sports and in case she should win it would bring her name into decided prominence before a large number of people on the other hand it would not be advisable to enter a team which would be easily defeated and would in no way be to the honor of the college the committee therefore earn estly desires that all men who have any ability in this line should come and try for it the track at rittersville where the training will be done is very good and that should be no draw-back the committee will adopt fixed standards of time and if they are equalled the way they should be the committee will then definitely accept the invitation junior german the junior german was not held before easter this year on account of being unable to obtain a con venient date but it will be held on the first friday after easter the day before tne mustard and cheese performance the committee have already begun work and the dance will undoubtedly be one of the most successful ones of the season the picture of the brown and white board was taken by eggert yesterday afternoon at the university of chicago the university press assumes the responsibility of managing distri buting and printing its six journals its books pamphlets and other publications sophomore class meet ing there was a meeting of the sopho more class at 12.30 o'clock tues day at which elections for treas urer and athletic representative were held after two ballots shepp was elected treasurer by a large majority no one obtaining a sufficient number of votes to con stitute an election in the vote for athletic representative the election was postponed after a few re marks from the president on the subject of the winter meet the meeting was adjourned a new paper called the morn ingside will shortly be published at columbia it will be devoted to fiction and verse lehigh university south bethlehem pa thursday february 20 1896 the brown and white isto 38 vol 111 agora meeting the special meeting of the agora was held yesterday afternoon in the lounging room at christmas hall at 3 o'clock president laramy presided the business before the meeting was to decide the question that should be presented to lafay ette for the annual debate the dis cussion finally narrowed down to two subjects — first governmental control of railroads and second a single gold standard in com parison with bi-metallism after remarks by messrs hess hood mckenzie and thurston the first question was taken and put in the following form for presentation to lafayette : " resolved that the united states goverment should own the railroads the names of ten men were then drawn to be presented to lafayette as judges there being no further business the meeting adjourned calendar friday feb 21 — meeting of chess club in lounging room 8 p.m saturday feb

saturday afternoon promises to be in every way a great success the number of entries is very large and especially in the boxing and wrest ling great interest seems to have been aroused special arrangements have been made for any who desire j to bring ladies to the meet for prizes handsome souvenir flags will be given in the boxing and wrestling the entries are so numerous that it will in all probability be necessary to have preliminary bouts which will be run off friday afternoon a suitable announcement will be given if it is deemed expedient to make such an arrangement the other events will consist of the ones which are usually held namely : running high jump,stand ing high jump running high kick running broad jump fence vault etc one of the chief attractions will be a gymnastic exhibition by a friend of mr smith's in philadel phia it was first thought that professor herman would be able to do it but on account of his hand he will be unable to come but will send some one in his place all in all the meet promises to be a most enjoyable event notices the electrical engineering so ciety will meet in the physical la boratory tonight at 7 o'clock pa pers wiil be read by loomis 96 in " the electrical equipment of a ship and worstall 96 on " the latest improvements in power stations the subjects are of par ticular interest and a good meeting is expected hall president a regular meeting of the c e society will be held in the physi cal laboratory this evening feb 20 at 7p m the subject for the evening will be the east jersey water company pipe line herr 96 and curtis 97 will have papers on the subject the meeting should be of interest to juniors and seniors alike secretary a lehigh number of the american ma chinist the place of honor in the last issue of the american machinist is held by an article written by w"sl ter ferris 95 95 mr ferris de scribes a test made while he was in college to determine the beha vior of the governor of a high speed engine under charges of load : the test was made in connection with prof klein's work on this subject the experiments described are of general interest not so much for the results obtained as by reason of the ingenuity displayed in con structing and adapting the neces sary apparatus this was gotten up from rather small beginnings and enabled one observer to do work apparently requiring two or three in the same number is a quite extensive and on the whole a quite favorable review of the circular re cently issued bythem.e.department the practical side of the course is chiefly touched on and the methods employed here in drawing room and on shop visit are commended the lack of shop work is noted as a radical omission from the course — but with a strong word in favor of making shop experience a pre liminary to not a part of an engi neering course mathematical club meeting
