Report of the President 39 



Museum, a series given on Tuesday and Saturday evenings, 

 from October to May, under the auspices of the Board of 

 Education, free lectures on public holidays, special lectures 

 in conjunction with the New York Academy of Sciences and 

 Affiliated Societies, and a course of Jesup Lectures, given 

 under the auspices of Columbia University. The attendance 

 at these lectures was 61,157. 



Children's Room. — The Children's Room has been re- 

 modeled to give it greater seclusion, and several new exhibits 

 have been added. These include a collection of dolls of all 

 peoples and a series of interesting and bizarre fishes. The 

 room has been open regularly on Wednesdays and Saturdays, 

 except during August and September. The attendance for the 

 year was 3,108. 



The Museum participated in the Child Welfare Exhibit, 

 held in the Seventy-first Regiment Armory, in January and 

 February. 



Room for the Blind. — Probably no collections in the 

 Museum give greater pleasure or are more highly appreciated 

 than the collections examined by the blind. The difficulty 

 experienced by the blind in reaching the Museum, combined 

 with their natural timidity, is one reason why the attendance 

 has not been greater. A portion of the income of the Jona- 

 than Thorne Memorial Fund is being devoted to the prepara- 

 tion of relief maps and models of animals to be loaned to the 

 public schools where the blind are taught. In April the 

 Museum participated in the Blind Workers' Exhibit at the 

 Metropolitan Opera House. 



Photography. — The photographic work has been of 

 a routine nature. The reference file of photographs now 

 numbers over 26,000; the file of negatives numbers over 

 20,000; the file of lantern slides numbers over 35,000, of which 

 about 15,000 are colored. 



Mr. A. Radclyffe Dugmore has deposited in the Museum 

 his entire series of negatives, taken in 1909, and the Museum 

 has acquired also 535 negatives of reptiles and amphibians,
