Clifford Whitman Bates, Charles Douglas Galloway and William E. Saunders; lectures before Sections by I.. W. Austin. Ph.D., Head, U. S. Naval Radio Research Laboratory, Bureau of Standards, Washington. District of COlumbia, on " Recent Developments in Radio Communication "; by L. J. Henderson, M.D., Professor of Biological Chemistry, Harvard University, Cambridge, Massachusetts, oll " Applications of Physical Chemistry to the Physiology of B r e a t h i n g " ; lecture before the Stated Meeting January I8, i922, by Honorable William D. B. Ainey, LL.D., L . H . D , Chairman of the Public Service Commission of Pennsylvania on " The Highway System of the State of Pennsylvania "; and additions to the library by gift. 42 volumes and I56 pamphlets, by purchase 44 volumes. L. J. Briggs, M.S., Ph.D., Chief of Engineering Physics Division, Bureau of Standards, Washington, District of Columbia, presented the paper of the evening on " The Resistance of the Air." Wind-tunnels for obtaining airstreams of known velocity were described as well as aerodynamical balances for measuring air forces on a model; reference was made to the air-resistance equation and dynamical similarity in air-resistance measurements. Consideration was given to the air-resistance of bodies of various forms and to air-foils. Reference was also made to the problem of the measurement of the resistance of projectiles. The subject was illustrated by lantern slides. A unanimous vote of thanks was extended to Doctor Briggs. Adjourned.
