soap method also gives excellent results with specimens which 

 have previously been preserved in alcohol. 



The equipment in the preparation room remains very in- 

 adequate. Quarters having much larger space, better light 

 and adapted to the installation of a necessary degreasing ap- 

 paratus are the most pressing needs of the department. 



An exhibition space in the west corridor of the second floor 

 has been allotted to the department, where it is hoped in the 

 near future to install exhibits illustrating such functions as the 

 mechanism of respiration, the structure and functions of the 

 kidneys and the action of the heart. 



The department has received in the flesh 101 specimens 

 from the Central Park Menagerie, 179 from the New York 

 Zoological Society, 18 from the New York Aquarium and 39 

 from other sources, making a total of 337 animals. 



PUBLIC HEALTH 



Charles-Edward Amory Winslow, Curator 



Department of Public Health. — A joint exhibition of 

 models, charts and pictures, illustrating the problems con- 

 nected with the pollution of New York Harbor, and practical 

 methods for the disposal of city wastes, was made during the 

 months of May and June by the Department of Public Health 

 and the Metropolitan Sewerage Commission. At the opening 

 meeting on May 15, addresses were made by President Osborn, 

 Dr. G. A. Soper of the Commission, Dock Commissioner Tom- 

 kins, Dr. H. W. Wiley of the United States Bureau of Chem- 

 istry, and the Curator. On the closing day, Friday, June 16, 

 special lectures were given to 1,200 pupils from the city high 

 schools, who made a visit to the exhibition. 



The principal work of the department has since been 

 devoted to the preparation, under the immediate direction of 

 Mr. J. H. O'Neill, of a series of models, relief maps, charts 

 and specimens, to illustrate the natural history of drinking 

 water. This exhibit, when completed, will show the original 

 source of water, in the rainfall with its local variations, the 

 methods used in getting water supplies by damming streams
