connection with the fresh-water fishes of Ceylon. I have 

 mentioned elsewhere the hot springs of Kannea, in the 

 vicinity of Trincomalie, the water in which flows at a 

 temperature varying at different seasons from 85 to 115. 

 In the stream formed by these wells M. Keynaud found 

 and forwarded to Cuvier two fishes which he took from 

 the water at a time when his thermometer indicated a 

 temperature of 37 Keaumur, equal to 115 of Fahrenheit. 

 The one was an Apogon, the other an Ambassis, and to 

 each, from the heat of its habitat, he assigned the specific 

 name of " Thernaalis." 1

on the water being thawed, the fish 

 became as lively as usual. Dr. 

 KICHARDSON, in the third vol. of his 

 Fauna Borealis Americana, says the 

 grey sucking carp, found in the fur 

 countries of North America, may be 

 frozen and thawed again without 

 being killed in the process. 



1 CUT. and VAL., vol. iii. p. 363. In 

 addition to the two fishes above named, 

 a loche Cobitis thermalis, and a carp, 

 Aw/to tJiermoicos, were found in the 

 hot-springs of Kannea, at a heat 40 

 Cent., 114 Fahr., and a roach, Leu- 

 ciscus thermal^, when the thermo- 

 meter indicated 50 Cent., 122 Fahr. 

 Ib. xviii. p. 59, xvi. p. 182, xvii. 

 p. 94. Fish have been taken from 

 a hot spring at Pooree when the 



thermometer stood at 112 Fahr. 

 and as they belonged to a carnivo- 

 rous genus, they must have found 

 prey living in the same high tempera- 

 ture. Journ. Asiatic Soc. limy. vol. 

 vi. p. 465. Fishes have been observed 

 in a hot spring at Manilla which 

 raises the thermometer to 187, and in 

 another in Barbary, the usual tempe- 

 rature of which is 172; and Humboldt 

 and Bonpland, when travelling in 

 South America, saw fishes thrown up 

 alive from a volcano, in water that 

 raised the temperature to 210, being 

 two degrees below the boiling point.
