body. He repeated the experiment of taking out 

 the brain upon several other Tortoises, both of 

 land and fresh water ; all of which lived for a con- 

 siderable space without the brain. He observed 

 also, that having cut off the heads of some, and 

 opening the bodies twelve days afterwards, the 

 motion of the heart was still perceptible ; so slowly 

 is the vital principle discharged from these inac- 

 tive animals. 



The species of Testudo most liable to be con- 

 founded with the Graeca seem to be the T. pusilla 

 of Linnaeus, the tabulata of Schoepf, the sulcata 

 of Millar, and the marginata of Schoepf. Linnaeus 

 himself quotes no figure for his T. Grasca, which 

 has greatly tended to increase the general uncer- 

 tainty.

THIS, according to Mr. Schoepf, is the species 

 erroneously figured and described in the Count de
