on the surface of the water, and thus being almost always in 

 sight. It lias been introduced into England by Lord Arthur 

 Russell, and placed in a lake at Wobuni Abbey, from which it 

 is probable that it will be distributed into other portions of 

 the United Kingdom. Specimens were lately brought to the 

 United States and placed in the ponds of Dr. Slack at Blooms- 

 bury, New Jersey. 



A writer in the London Field remarks in reference to this fish 

 that it forms a parallel to the gold-fish of China, which in its 

 typical form is b} T no means golden, but olivaceous and silvery, 

 and that the redness represents a peculiar form of albinism, 

 which has become permanent. 19 A,March 28, 1874, 299. 



LONGEVITY OF FISHES. 



Dr. Buchner, of Giessen, presents to the Dorpat Natural 

 History Society his contribution to the facts bearing upon 

 the longevity of fishes, in which he remarks that a large eel 

 is now living in a stone trough about ten feet long, with a 

 board top, through which is continually running a stream of 

 cold water. The eel has been kept in that trough for twenty- 

 six years, and now measures nearly five feet in length, the 

 w T eight about a year and a half ago being four and a half kil- 

 ogrammes. The length of the fish when placed in the trough is 

 not known, but its weight was one and a quarter kilogrammes. 

 It was estimated to be about eight years of age at that time, 

 and consequently would now be thirty-four. The food of 

 this animal consists of small trout, of chopped liver, and of 

 coagulated blood. Dorpat Nat. Hist. Soc, III., 1872, 312. 



SPAWNING OF WHITING-POUT. 



According to the observations of Mr. Henry Lee upon 

 whiting-pout (Gadus luscus), a small species of gadus kept 

 in the Brighton aquarium, the spawning season of these fish 

 is about the middle of November, the eggs being so numer- 

 ous as actually to cloud the water of the tank in which they 

 are contained, each globule being a little smaller than a 

 granule of boiled sago. Their specific gravity is nearly that 

 of sea-water, and when placed in perfectly still water, when 

 the embryo is developed, they exhibit a tendency to sink to 

 the bottom ; but if the water is agitated they rise, and some 

 time elapses before they again settle.
