physical laboratory with a large proportion of the members present the first paper of the evening was on the construction of steel ships by l c wright 11 last summer mr wright worked for the maryland steel company in their ship building yard at sparrows point and gave many interesting items entering into the construction of the steel ships built by them as perhaps every one knows the walnut lane bridge over the wissahickon creek near philadel phia is the largest finished con crete arch bridge in the world mr h h quimby who de signed this bridge being at the time in the department of bridges of philadelphia gave a very detailed account of its design and construc tion illustrated with many stere opticon views mr quimby also showed some diagrams pertaining to the relation between the tem perature in the arch and its expan sion the temperature has been taken daily since the completion of the bridge from an electric ther mometer in the center of the arch at the crown after describing some smaller concrete bridges of novel design built where the eleva tion of the street and the headroom below were such as to require a special design mr quimby brought his lecture to a close with some very optimistic views on the future of engineering y m c a meeting practice notices basket ball practice is held in the gymnasium during the follow ing hours tuesday 4 to 6 p m wednesday 2/30 to

society was held in the physical labora tory on tuesday the bth at 7.30 p m owing to a business matter in washington mr l b stillwell president of the american institute could not be present as expected but the papers of the evening were well prepared and mr stillwell is expected to address a later meeting the first article was by g f r bahnson 10 on transformation of electrical energy to light and this topic was entered into very deeply some parts being beyond the grasp of the audience when an incandescent lamp is placed in an electric circuit part of the elec tric energy is transformed into light and part into heat the part that is transformed into light is the useful part and this part is so small that the efficiency of an incandescent lamp is measured in fractions of a per cent while this efficiency may seem small it is greater than either gas or kerosene there are numerous filaments used in incan descent lamps at the present time and each has its merits the popu larity of the tungsten filament over the carbon on account of its higher efficiency is due to the fact that the metal tungsten has a lower boiling point than carbon and naturally is operated at a lower temperature therefore the percentage of useless heat transformation is smaller in the tungsten than in the carbon filament and the tungsten has a higher efficiency the greatest efficiency however is obtained from the electric arc the nernst lamp displays selective radition on the same principle as the welsbach gas mantle the mercury arc is adapted to suburban lightning on account of the pleasing tones it adds to the color of foliage and it is used in shops and mi 11s the calcium light is used for advertising purposes on account of its glare on storage batteries e a warner,'lo described the principal forms of the lead type now in use and the uses to which they are put the society then adjourned to the library on the second floor where refreshments were served this room has
