Tortoises and turtles may be prepared in a dry state, 

 the breastplate being separated by a knife or saw from 



t 



he back, and, when the viscera and fleshy parts have been 

 removed, restored to its position. The skin of the head 

 and neck must be turned inside out as far as the head, 

 and the vertebrae and flesh of th.e neck should be detached 

 from the head, which, after being freed from the flesh, 

 the brain, and the tongue, may be preserved with the skin 



of the neck.

In skinning the legs and the tail, the skin 



places by re-drawing the skin over them, first winding a 

 little cotton or tow round the bones to prevent the sl:in 

 adhering to them when it dries. 



When turtles, tortoises, crocodiles, or alligators, are too

large to be preserved whole in liquor, some part 



as the 



head, the whole viscera stripped down from the neck to 

 the vent, and the cloaca, should be put into spirit or solu- 

 tion. The bones of such specimens are especially desi- 

 rable : they may be separated and scraped clean : all 

 those of the same individual should be packed in a bag 



or box with bran, paner-cuttings, hay or < 



iried seaweed.

 After detaching as much of the flesh as is practicable, the 

 entire skeleton maybe suffered to dry in a naturally con- 

 nected state, and then may be laid in a box on cotton, 

 tow, or other suit material, and covered with the saixxO.
