arranged to be held, one by Dr. Stewart Paton 
on the “Psychology of the Aviator”; the 
other by Dr. Alonzo Taylor on the “ World’s 
Food Situation,” have been postponed on ac- 
count of the departure of these men for Eu-

ally arranged as follows:

fectious Diseases in the Army.’’

THE AMERICAN SOCIETY OF NATURALISTS 
Tue American Society of Naturalists, in 
affiliation with the Botanical Society of Amer- 
ica and the American Society of Zoologists, 
will hold its thirty-sixth annual meeting at 
Baltimore, under the auspices of Johns Hop- 
kins University, on Saturday, December 28, 
1918. 
The Botanical Society of America will place 
the genetical papers of its program on Friday 
morning, December 27, and the American So- 
ciety of Zoologists will group its genetical 
papers in a program for Friday afternoon. By 
this arrangement there will be sessions of in- 
terest to the members of the American Society 
of Naturalists on the day preceding the meet- 
ings of the society. 
The American Society of Naturalists will 
offer, beginning Saturday morning, December 
28, a program to which members of the society 
are invited to contribute papers. 
The customary symposium of the Natural- 
ists will this year be omitted. Well developed 
plans of the program committee were disar- 
ranged by conditions of the times at a date too 
late for readjustments.

The Naturalists’ dinner, in which members 
of the affiliated societies are invited to partici- 
pate, will be held on the evening of Saturday. 
At the close of the dinner Vernon L. Kellogg 
will talk on “ The German philosophy of war.” 
Titles of papers offered by members of the 
society, with estimated length of delivery and 
statement of lantern or chart requirements, 
must be in the hands of the secretary by De- 
cember 1. It is desired that papers be short 
and it should be remembered that the interests 
of the Naturalists are primarily on problems 
of organic evolution. The papers on the pro- 
gram will in general be arranged in order of 
the receipt of title except that papers on simi- 
lar subjects may be grouped. 
Attention is called to the change in the con- 
stitution by which a nomination for member- 
ship must now remain in the hands of the ex- 
ecutive committee for at least one year before 
action can be taken upon it. Therefore, nomi- 
nations to receive attention in 1919 must reach 
the secretary by December 31, 1918. Blank 
forms for nominations may be obtained from 
the Secretary. 
Headquarters of the Naturalists will be at 
the Hotel Rennert, Liberty and Saratoga 
Streets. Members are advised to make early 
reservations. <A list of boarding houses will be
