 very heavy seine required to hold animals so active. 



Another species of porpoise (Delphinus delphis) captured 

 on the coast of New Jersey, was exhibited at the Aquarium in 

 October. 



This specimen, like all of the porpoises received from fisher- 

 men, was injured and lived only two days. A specimen of the 

 small harbor porpoise {PJiocsena communis), taken at Prov- 

 incetown, Mass., in October did not reach the Aquarium alive. 



Porpoises to endure captivity must be taken uninjured and 

 kept in tanks of cool water from the moment of capture until 

 placed in the pool at the Aquarium. Our experience has shown 

 that this can be done without great difficulty or expense. 



The porpoises lost in June were presented by the Zoological 

 Society to the American Museum of Natural History, New York, 

 the Academy of Natural Sciences, Philadelphia, the Museum of 

 the Brooklyn Institute, the College of Physicians and Surgeons, 

 New York, and the Oceanographic Museum, Monaco. The soft 

 parts of most of the specimens were utilized by the College of 

 Physicians and Surgeons. It is well that other institutions 

 derive some profit from our misfortunes. 



The porpoises lost from pneumonia, died from the malady 

 that sooner or later carries off our seals and manatees, and re- 

 sults from attempts to keep out-of-door animals in a heated 

 building in winter, without the advantages of a specially venti- 

 lated section which such animals require. All captive lung- 

 breathing marine mammals exhibited indoors, should be separ-
