THE WASHINGTON MEETING OF THE 
AMERICAN CHEMICAL SOCIETY 
AGAIN the American Chemical Society has held 
the largest meeting in its history, 658 members 
and guests registering in Washington, and prob- 
ably 700 were present. 
The meeting opened on Wednesday, December 
27, with a joint meeting of the Section on Chem- 
ical Education and the Division of Physical and 
Inorganie Chemistry, at which the following four 
papers were given: 
A. A. Noyes (chairman) : 
Physical Chemistry. 
W. D. Bancroft: 
Introductory Course. 
H. C. Jones: The Introduction of Physical 
Chemical Conceptions in the Harly Stages of the 
Teaching of General Chemistry. 
J. Howard Mathews: Some Applications of 
Color Photography in the Teaching of Physical 
Chemistry (illustrated). 
In the afternoon the address of Vice-president 
Frankforter, of Section C, entitled ‘‘The Resins 
and their Chemical Relations to the Terpenes,’’ 
was delivered before a large audience and was 
followed by an address by Chairman H. P. Talbot 
on the subject ‘‘ Privileges and Responsibilities of 
the Chemical Analyst.’’ Following Dr. Talbot, 
Dr. A. L. Voge, of the Library of Congress, read 
a paper on ‘‘Ostwald’s Proposed International 
Institute of Chemistry.’’ 
Throughout the week the society’s Divisions of 
Agricultural and Food Chemistry, Biological 
Chemistry, Industrial Chemists and Chemical En- 
gineers, Fertilizer Chemistry, Organic Chemistry, 
Pharmaceutical Chemistry, Physical and Inorganic 
Chemistry and the Chemistry of India Rubber, 
held meetings in rooms especially assigned to them. 
Some 500 were present at the ‘‘smoker’’ on 
Wednesday evening, which was fully up to. the 
standard of the well-known smokers of the Chem- 
ical Society. 
On Thursday evening Alexander Smith, presi- 
dent of the society, delivered his presidential 
address, entitled ‘‘An Early Physical Chemist,’’ 
and was followed by an interesting lecture by 
Frank B. Kenrick and H. E. Howe, consisting 
chiefly of illustrations by means of the lantern of 
the effect of temperature, pressure, concentration, 
surface tension, osmotic pressure, etc., on reac- 
tions in heterogeneous systems. 
A feature of the divisional meetings was the 
The Teaching of 
Physical Chemistry in the
