It is expected that the successful completioni of any of the courses will be recognized for adequate credit in some of our better educational in- stitutions, both for undergraduate and for postgraduate work. This has already been the case with the Bureau of Standards courses.

Those offered this year at the Bureau of Standards include: Ad- vanced optics by Dr. C. A. Skinner; differential equations by Dr. L. B. Tuckerman; chemical thermodyna- mics by Dr. L. H. Adams of the geophysical laboratory; interpreta- tioin of data, including Ihe theory of errors and methods for numerical, graphical and mechanical computa- tioll, by Dr. Chester Snow.

The courses of study at the De- partment of Agriculture were worked out by a committee from the various bureaus of the department headed by Dr. E. D. Ball, formerly assistant sec- retary and now director of the sci- entific work of the department.

There are two more or less distinct kiinds of work offered: (a) lecture and drill courses on certain funda- mental subjects in which the per- sonnel of two or more bureaus may be interested; (b) intensive gradu- ate training in special topics.

The courses now being given at the Department of Agriculture are: Agricultural Economics, by Dr. H. C. Taylor; Statistical Methods, by H. R. Tolley; Biochemistry, by Dr. C. 0. Appleman; Mycology, by Dr. C. L. Shear; Plant Physiology, by Dr. Burton E. Livingston; Genetics, by Dr. Sewall Wright; Physics of the Air, by Dr. W. J. Humphreys; Stat- istical Mechanics applied to Chemical Problems, by Dr. R. C. Tolman.

THE OPTICAL SOCIETY OF AMERICA

At the sixth meeting of the Optical Society of America, held in Roches- ter, N. Y., the most notable feature was the Helmholtz Memorial Meet-

ing held on the afternoon and eveln- ing of October 24. The afternoon program was as follows:

A brief survey of the histor-ical developmnent of optical scicence: PRO- FESSOR J. P. C. SOIJTHALL.

Helmho ltz's carlAy work in physics- the coniservationt of elegy): PROFES- SOR HENRY CREW.

Helmnholtz's contributions to phys- iological optics: L. T. TROLAND.

Professor Crew exhibited lantern slides showinlg Helmholtz at the time he wrote the essay on the Conserva- tion of Energy (age 26) and also at later periods of his life.

At the eveninlg session, Professor M. T. Pupin spoke informally and in a most interesting and delightful manner on his Personal Recollections of Helmholtz. Professor E. L. Nichols, Professor Ernest Merritt, Dr. Ludwik Silberstein, Mrs. Chris- tine Ladd-Franklin and Professor C. R. MTann also spoke of their memories of Helnmholtz as a teacher. Professor Mann showed a lantern slide of a photograph which he himself made on July 7, 1894, showinlg Helmlholtz at his lectun-e desk only a few days before his last illness.

At the regular sessions of the so- ciety some twenty papers were pre- sented, special attention being given to physiological optics. A commit- tee was appointed, the duty of whichi is: (I) To prepare the program of the sessions onl vision; (2) to co- ordinate the work of the society in this field with the work of other so- cieties and (3 ) to reconmmend, from time to time, such further steps as may be deemed effective in encour- aging research in physiological optics and allied problems.

Rochester is the wvorld's chief cen- ter for the manlufacture of optical and photographic apparatus. Visits were arranged to go through the re- search laboratories of the Eastman Kodak Company and the glass plant, optical slhops and observatory of the Bausch alnd Lomb Optical Company. The research work of these labora- tories is of great magnitude and even in contributionls to pure science may soon rival the chemical and physical laboratories of alny university.
