30 Report of the President. 



purposes of study, and about 50,000 people have been present 

 at the various public lectures. 



Associated Societies and Organizations. — The two 

 small assembly rooms have been improved by changes remedy- 

 ing, in a great measure, their defective acoustic properties, 

 and throughout the year they have been in great demand for 

 the meetings of various scientific societies which have sought 

 affiliation with the Museum. Occasionally the large auditorium 

 has been required for the accommodation of such organizations. 



Early in the year the Board of Education of the City asked 

 permission for the temporary use of one of the exhibition 

 halls in which to install the collections illustrating the work 

 done in the public schools, and comprising the exhibit of the 

 Board at the St. Louis Exposition. This was desired in order 

 that the public might become more familiar with the work 

 that the schools are doing, and that the teachers might have 

 an opportunity to study the methods and results of others. 

 The East Mammal Hall was assigned for this purpose and 

 was occupied by the school exhibit from March till August. 



In November the Siberian Hall was given over to the 

 American Tuberculosis Exhibition for the display of an 

 instructive exhibit showing the results of the dread disease 

 and the best methods to check its spread. In connection 

 with the exhibition eminent men delivered lectures at the 

 Museum on various phases of this important subject. The 

 Board of Health of the City was given permission to use one 

 of the small assembly rooms for the temporary installation of 

 its exhibit at the St. Louis Exposition. 



The following societies and classes have shared the hospi- 

 tality of the Museum during the past year: 



New York Academy of Sciences. 

 New York Entomological Society. 

 Linnsean Society of New York. 

 New York Mineralogical Club. 

 Audubon Society of the State of New York. 



National Association of Audubon Societies for the Protection of Wild
