TWENTY-FIRST ANNUAL REPORT 53 



RATTLESNAKE SERUM. 



The Society expects to secure from Dr. Vital Brazil of Sao 

 Paulo, Brazil, 250 tubes of rattlesnake serum, of which 50 will 

 be retained by the Society, and 200 will be turned over to the 

 Surgeon General of the U. S. Army for use among the troops 

 on the Mexican border. 



MEDICAL DEPARTMENT. 



The general health of the animals has remained good dur- 

 ing the year, and now that we have a hospital for the proper 

 care of the animals, our losses will probably be reduced to a 

 minimum. The arrangements for the disposal of dead animals 

 with the Prosector, Dr. George S. Huntington, and with the 

 American Museum of Natural History, are working smoothly. 

 Whatever autopsy is needed for Park purposes, it is performed 

 at the Park, and the skeleton and skin are sent for mounting 

 purposes to the American Museum of Natural History. All tis- 

 sues and soft parts, including also such bony structures as are 

 not needed by the American Museum, are turned over to the 

 Prosector for his research work. 



TROPICAL RESEARCH STATION. 



The Zoological Society's Tropical Research Station was es- 

 tablished in British Guiana, early in 1916, under the personal 

 direction of its Director, Mr. Wilham Beebe. Mr. Beebe was 

 ably assisted throughout the year by Mr. G. Inness Hartley, as 

 Research Associate, and Mr. Paul G. Howes, Research Assistant. 

 The site selected for the Station was at the confluence of the 

 three great rivers Essequibo, Cuyuni and Mazaruni. 



The locality chosen proved exceedingly rich in wild life, 

 and it is no exaggeration to state that the workers reaped an 

 exceptionally rich harvest of results. 



In the autumn the whole party returned to New York and 

 at once entered upon the exploitation of the results of the tropi- 

 cal work. In the spring of 1917, there will appear, as the first 

 annual report of the Station, a large illustrated volume, which 

 will be a revelation of zoological work in a new field. In addition
