OBSERVATIONS ON INSECTS AND VERMES. 42$ 



have been newly cast. From circumstances it appeared as if 

 turned wrong side outward, and as drawn off backward, like a 

 stocking or woman's glove. Not only the whole skin, but scales 

 from the very eyes are peeled off, and appear in the head of the 

 slough like a pair of spectacles. The reptile, at the time of 

 changing his coat, had entangled himself intricately in the grass 

 and weeds, so that the friction of the stalks and blades might 

 promote this curious shifting of his exuviae.

Exuit in spinis vestem." LUCRET. 



It would be a most entertaining sight could a person be an eye- 

 witness to such a feat, and see the snake in the act of changing his 

 garment. As the convexity of the scales of the eyes in the slough 

 is now inward, that circumstance alone is a proof that the skin has 

 been turned j not to mention that now the present inside is much 

 darker than the outer. If you look through the scales of the 

 snake's eyes from the concave side, viz., as the reptile used them, 

 they lessen objects much. Thus it appears from what has been 

 said, that snakes crawl out of the mouth of their own sloughs, and 

 quit the tail part last, just as eels are skinned by a cook maid. 

 While the scales of the eyes are growing loose, and a new skin is 

 forming, the creature in appearance must be blind, and feel itself 

 in an awkward uneasy situation. WHITE. 



I have seen many sloughs or skins of snakes entire, after they 

 have cast them off; and once in particular I remember to have 

 found one of these sloughs so intricately interwoven amongst some 

 brakes that it was with difficulty removed without being broken ; 

 this undoubtedly was done by the creature to assist in getting rid 

 of its encumbrance. 



I have great reason to suppose that the eft or common lizard 

 also casts its skin or slough, but not entire like the snake ; for on 

 the 3oth March, 1777, I saw one with something ragged hanging 

 to it, which appeared to be part of its old skin. MARKWICK.
