TWENTY-SECOND ANNUAL REPORT 95 
chemicals. An urgent request of one of the largest manufac- 
turers of photographic supplies in America,—and perhaps in the 
world,—for old negative glass, is a striking example of the part 
that foreign materials have played in American-made products. 
A good stock of several important chemicals was obtained by 
this department at the beginning of the war, and by practicing 
the strictest economy it is yet available. 
Bulletin —Six numbers of the Zoological Society Bulletin 
were issued in 1917. Inasmuch as the Park is the chief source 
of supply for material for the Bulletin, the lack of new acces- 
sions has been keenly felt. Mr. Ellis Joseph’s collection from 
Australia, and the collections of the Research Station have come 
in most opportunely. A large part of the paper stock, purchased 
early in 1917, is yet available, and will last for several months 
of this year. 
Annual Report.—The report for the past year was issued 
as heretofore. 
Zoopathologica.—Dr. George A. MacCallum contributed the 
second number of this publication entitled Some New Forms of 
Parasitic Worms. 
Tropical Wild Life-—The Society’s first year’s work at the 
Station in the tropics of Guiana has been recorded in a handsome 
octavo volume of over 500 pages. The text is by Mr. Beebe, Mr. 
Hartley and Mr. Howes and the illustrations, numbering 143, 
are from photographs by the authors. A careful review of the 
book will be printed in the May, 1918, number of the Bulletin.
