FIFTH ANNUAL REPORT. 41 
PUBLICATIONS. 
The publications of the Society during the year 1900 consisted 
of the Fourth Annual Report, and Bulletin No. 4, which were 
published early in the spring and sent to all members of the So- 
ciety. Of the latter, an extra edition of 5,000 copies was printed 
and widely distributed in order to increase the general public 
interest in the Zoological Park. 
A change in the form of the Bulletin is contemplated which 
will give it a more permanent character, and gradually make it 
an appropriate medium of publication of more or less scientific 
communications. An official bulletin describing the methods of 
the Zoological Park work, and improved treatment of animals, 
new modes of installation, observations upon the habits of animals 
in captivity, would render great service to the cause of zoological 
parks in this country. Already we find cities of the United States 
turning to us for advice. The Chairman has recently received 
a communication from Japan requesting the transmission of all 
the publications of the Society, to aid in the establishment of a 
Zoological Park in Kioto, and the ground plans of our Lion 
House have been furnished the Zoological Society of Dublin, by 
its request. 
In addition to the Fourth Annual Report, which was widely 
distributed, the Guide Book prepared by Director Hornaday has 
proved very successful, and has had an extensive sale in the 
Park. Three thousand copies of the first edition were printed. 
A second edition of 3,000 was also disposed of, and a third edi- 
tion of 5,000 copies, revised and improved by the addition of 
many new plates, has just been printed. Copies of this will forth- 
with be supplied to all members. 
The Chairman proposes the preparation of a popular book 
upon the Zoological Park, richly illustrated by photographs, with 
anecdotes, with a popular description of the animals, for sale 
in the New York book-stores, as a means of spreading the gen- 
eral knowledge of the Zoological Park. 
PHOTOGRAPHY. 
Considerable progress has been made with photography, and 
some very artistic and valuable photographs have been secured, 
chiefly the work of Mr. Ernest F. Keller. Altogether the collec-
