ADDENDA. 99 



December 2d. To feed the large one is both tedious and troublesome. 

 Cutting a thin narrow portion of the soft of a mussel, it is to be taken 

 up or secured tightly in the rib of a feather of a quill, from which it may 

 be easily detached ; then it must be sunk in the water, and presented 

 almost close to the mouth of the Newt, — rather higher than the mouth, a 

 little on one side ; the animal will approach very softly and snap at it. 

 I could in no other way induce it to feed. The lower jaw opens down- 

 wards, very wide. 



\Qth. The young Newt had a narrow escape. Some days ago a por- 

 tion of mussel was introduced to its vessel, in expectation of its being 

 strong enough to feed : this was neglected to be speedily removed, and, 

 on the 8th, I found the Newt at the point of death. 



It could scarcely move, though the water had no foetor ; being 

 immediately transferred to a vessel with water quite fresh, it recovered 

 in twenty-four hours. 



On the 12th I fed the larger one, which had become so extremely 

 tame, and looked so innocent. 



13///. This morning I conceive it had crawled out of its glass. 1 

 missed it at mid-day. But it had been found previously, and unluckily 

 committed to a vessel of sea water, wherein, to my great regret, I found 

 it dead. 



It had been taken on the 8th September 1840.
