 Among the larger varieties I may mention whales, man-eating 

 sharks, bottle-nose dolphins, porpoises, sword fish, sun fish, 16

 elephants, tigers, lions, bears, giraffes, ostriches, chimpanzees, 

 and smaller varieties of nearly all the known kinds of fish, ani- 

 mals and birds. In 1879, I put in the lake of August Belmont, 

 Esq., at Babylon, Long Island, 65,000 young trout. Such is 

 some part of my experience, and with the experience I have 

 had aside from the above details, I make claim to the title of 

 Naturalist. Very respectfully,

 It always appeared to me too much like a set picture ; certainly 

 nothing could be learned from it, for nothing has a chance to 

 germinate in the water used in such a manner. In public aqua- 

 riums in Europe, where there is a circulation, it will be found 

 that the water is allowed to flow in and out of a tank, but that 

 the water runs into a reservoir, and a continual circulation is
