One afternoon session was devoted toa 
symposium on the use of the microscope by 
teachers and private workers, in which the 
topic of Animal Histology was presented by 
Professor Gage, that of Bacteriology by 
Professor Bleile, and that of Botany by Pro- 
fessor Bessey. On Thursday evening the 
Society listened to the annual address of 
the President, Dr. William C. Krauss, of 
Buffalo, N. Y., on the subject : ‘Some Med- 
ico-legal Aspects of Diseased Cerebral Ar- 
teries.’ 
The Treasurer’s report showed that the 
Society ciosed the year practically even, 
and that nearly one hundred dollars had 
been added to the Spencer-Tolles Fund, 
making it now $653.36. When the fund 
N.S. Vou. X. No. 246 
reaches $1,000 it is expected to make use of 
the income for an annteal prize or grant for 
microscopical research. 
The following officers were elected for the 
coming year: 
Professor A. M. Bleile, Columbus, Ohio, President. 
Professor C.. H. Eigenmann, Bloomington, Ind., 
Vice-President. 
Dr. M. A. Veeder, Lyons, N. Y., Vice-President.

The Society was tendered an evening re- 
ception by Mr. J. F. Stone, who showed a 
fine series of views taken on his trip 
through the Grand Cafion of the Colorado 
River. The local committee gave visiting 
members and ladies a trolley ride around 
the city, besides providing in many other 
ways for the success of the meeting.

PROCEEDINGS OF THE SIXTEENTH ANNUAL 
CONVENTION OF THE ASSOCIATION OF 
OFFICIAL AGRICULTURAL CHEM- 
ISTS, HELD AT SAN FRANCISCO, 
JULY 5-7, 1899. 
THE sixteeenth meeting of the Association 
of Official Agricultural Chemists was held in 
San Francisco, July 5th to 7th inclusive, 
under the presidency of Dr. R. C. Kedzie, 
Chemist of the Agricultural Experiment Sta- 
tion of Michigan. There was a large attend- 
ance of agricultural chemists, not only from 
the Pacific, but also from the Atlantic 
coast. On account of the early date at 
which the Association met, making only a 
little over eight months from the time of 
the last meeting, it was found that many 
of the referees and their collaborators had 
not the time or the opportunity in which 
to complete the work intrusted to them. 
Anticipating this difficulty, the Secretary, 
several weeks in advance of the meet-
