ence from less than a dozen specimens. One of these, captured 

 in Florida waters in 1912, was carefully studied by Prof. Gud- 

 ger, who includes in his paper such limited information as exists 

 respecting other captures of this remarkable shark. 



Dr. Sergius Morgulis is at present conducting at the Aqua- 

 rium an extended investigation into the nutrition of fishes for 

 the United States Bureau of Fisheries. For this work Dr. Mor- 

 gulis has been provided with laboratory space and tanks neces- 

 sary for the pursuit of the work. 



Dr. W. H. Bates has been supplied with material and work- 

 ing space for his studies on the physiology and mechanism of 

 accommodation in vision. In the course of his experiments Dr. 

 Bates has examined the eyes of numerous species of fishes in 

 the Aquarium. A short paper in the November, 1914, Bulletin 

 explains in a simple way some of the results of these studies. 



Profs. George S. Huntington and H. von W. Schulte of the 

 Department of Anatomy of the College of Physicians and Sur- 

 geons have conducted the autopsies on the porpoises and other 

 mammals that have died during the past year. In all cases pul- 

 monary trouble seems to have been the immediate cause of death. 



As in former years the Aquarium has assisted many of the 

 public school teachers to establish balanced salt water aquaria 

 for the instruction of their classes. Sea water and sea lettuce 

 (ulva) are supplied together with sea anemones, shrimps, hermit 

 crabs, snails and whatever may be in stock at the time of the 

 request. The Aquarium has been at practically no expense in 

 this matter as the material has been brought in by our own col- 

 lector along with other things. These aquaria have been much 

 appreciated by the teachers. 



In addition to this some living material has also been sup- 

 plied to the College of the City of New York, Cornell Medical 

 College, The College of Physicians and Surgeons and Columbia 

 University for purposes of research. 



BIOLOGICAL WORK IN LONG ISLAND SOUND. 



The steamer Fish Hawk, one of the vessels of the U. S. 

 Bureau of Fisheries, was detailed in June and July for a biolog- 

 ical reconnaisance in Long Island Sound. 



This work was placed under the supervision of Dr. C. B. 

 Davenport, Director of the Marine Laboratory at Cold Spring 

 Harbor, and Dr. C. H. Townsend, Director of the Aquarium.
