them in holes in the clay, and sometimes ten or twelve coiled to- 

 gether. I have observed that either a very wet or very dry situa- 

 tion is fatal to the Triton during its state of hibernation, and that 

 a moderately damp one is always chosen for that state of existence ; 

 and further, that the Triton can live in a solid mass of ice without 

 injury. 



"About the last week in March the perfect Triton leaves the land 

 and becomes aquatic. It has then acquired all those appearances 

 which exist only during the breeding-season. They are absorbed 

 rather rapidly, and the animal leaves the water in August. 



" The Tritons of the third and fourth year are found during the 

 cold season in the earth under stones, in clusters of the magnitude 

 of a cricket-ball ; those of an earlier period are often found singly 

 at a greater depth under the earth, as before stated." — p. 381.
