in the building and was soon exhausted. The matter in the Bul- 

 letin has been largely rewritten in preparing the new pamphlet, 

 which will be kept permanently on sale for the benefit of the 

 public. This is the third attempt that has been made at the 

 Aquarium to supply such information. The original papers, pre- 

 pared by the Director some years ago, have passed through two 

 editions, but did not enter into the matter with sufficient detail. 

 Inquiry regarding small aquaria is still the principal subject in 

 the correspondence directed to the institution. 



Other pamphlets in continuation of this series are in prep- 

 aration. One of these will relate to the natural history of the 

 Bottle-nosed Porpoise, a species now attracting great interest as 

 one of the exhibits of the Aquarium. Another will be devoted 

 to the collection of tropical fishes from Florida and Bermuda. 

 All of these documents are abundantly illustrated from photo- 

 graphs of our own exhibits. The illustrations, having appeared 

 at various times in the Zoological Society Bulletin as half-tone 

 cuts, are now available for the nature series without extra cost. 

 The numbers already issued are: "Seashore Life," Mayer; 

 "The Cultivation of Fishes in Ponds," Townsend; "Changes in 

 Color among Tropical Fishes," Townsend; "Chameleons of the 

 Sea," Townsend; "The Northern Elephant Seal," Townsend; 

 "The Care of Home Aquaria," Osburn. Another number in 

 press is: "The Porpoise in Captivity," Townsend. 



The profits derived from the sale of these documents, as 

 well as from the sale of bulletins and postcards, are devoted to 

 the publication fund of the Aquarium. During the year the 

 funds derived from such sources amounted to $877.71. The sale 

 of postcards has been large enough to warrant the addition of a 

 new series of cards. 



Respectfully submitted, 



C. H. Townsend, 



Director.
