EIGHTEENTH ANNUAL REPORT 121 



visitors at the Aquarium is, so far as known, greater than that 

 of any other public museum of any kind in the world. 



It is an interesting fact that the attendance at the Natural 

 History Museum and the Art Museum in New York City re- 

 mains nearly stationary, notwithstanding the great size and al- 

 most priceless values of their respective collections. The Aqua- 

 rium can make no increase in its exhibits in the present build- 

 ing and its collections represent no money value of importance. 

 The fact that its attendance increases to an important degree is 

 a source of gratification.

The officers of the Aquarium have from time to time pre- 

 pared works relative to marine life, which have been placed on 

 sale in the building and have been sold at a profit. The latest 

 pamphlet of this series is entitled: "The Care of Home Aqua- 

 ria," and was prepared with the view of meeting the continual 

 inquiry from correspondents of the New York Aquarium on this 

 subject.
