Detrmfx-r &/. To f< , 1 the large one in both tedious and troublc*onu>. 

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

 up or so litly 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. 

 1 could in iu> other way induce it to feed. The lower jaw opens down- 

 wards, very wide. 



\0tfi. The young Newt bad 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 ; beinj: 

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

 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 1849.
