SECRETARY'S REPORT 139 



C. W. Phillips and P. R. Achenbach of the National Bureau of 

 Standards and R. W. Seiders of the General Services Administration 

 gave the Zoo valuable advice in connection with many of the problems 

 incidental to improving conditions in the penguin cage. 



The National Institutes of Health, the Armed Forces Institute of 

 Pathology, the Johns Hopkins Medical School, and the Neurophys- 

 iology section of Walter Reed Medical School have given valuable 

 assistance and advice in the treatment and handling of animals. The 

 zoological division of the U. S. Department of Agriculture Research 

 Center, Beltsville, Md., continued to identify parasites found on the 

 animals. 



Dr. Charles G. Curbin, associate veterinarian, medical division, bu- 

 reau of medicine, Food and Drug Administration, has supplied the 

 Zoo with surplus medicines, and the following commercial firms have 

 been extremely kind in furnishing drugs for use and for clinical trials : 



Lederle Laboratories. 



Schenley Laboratory, Inc. (pharmaceutical division). 



E. R. Squibb & Sons. 



Upjohn Co. 



Wyeth Laboratories. 



The DeVilbiss Co. lent equipment for experimental purposes. 



At the request of the Pan American Sanitary Bureau, a branch of 

 the World Health Organization, Ernest P. Walker, Assistant Direc- 

 tor of the Zoo, went to Mexico to photograph bats. Mr. Walker has 

 specialized in the photographing of mammals and has taken many pic- 

 tures of bats, both flying and at rest. Certain species in Central and 

 South America have been found to be involved in the spread of rabies. 

 There have been no satisfactory photographs or drawings that could 

 be used by public health workers and others to determine and demon- 

 strate the kind of bats that they might be studying or discussing. 

 Therefore, they desired photographs that could be used in this work. 

 Mr. Walker left Washington October 31 and returned December 22. 



NEEDS OF THE ZOO 



Because of the natural deterioration of structures and equipment, 

 and rising costs, the need for more funds for maintenance, repair, and 

 improvements becomes more critical every year. The newest of the 

 exhibition buildings are 19 years old, the reptile house is 25 years old, 

 and the bird house is 28 years old. These and the buildings and other 

 structures that were erected during the depression days now require 

 a constantly increasing amount of repairs. It has recently been neces- 

 sary to abandon 10 enclosures that have deteriorated to such an extent 

 that they can no longer be repaired. Large areas of the grounds 

 have had to be neglected entirely, or given scant care, in order that
