scales of tortoises ; the same variety of shark's teeth {Glosso 

 petra) ; spines of balistae ; palates, teeth, and scales, of various 

 fishes ; fossil wood ; impressions of ferns and reeds ; some 

 fragments converted into charcoal, and some rolled pebbles of 

 quartz." 



Dr. Buckland considers these two deposits to have been 

 formed under similar circumstances, at different and remote 

 periods ; M. C. Prevost regards them " as having been formed 

 at a period much newer than that of the oolitic formations ; in 

 short, that they are tertiary and not secondary deposits." — (Edin.

12. Heart of the Frog used for Poisoji. 



The Javanese, it is said, employ the heart of the frog 

 named kadok kesse for preparing a poison. The blood of the 

 reptiles is also considered as venomous, and is used for poisoning 

 daggers or knives. Jt is known that the blood of a frog is em- 

 ployed by the Americans for producing; variegated feathers in 

 parrots ; some of the feathers are plucked out, and the place 

 where they grew imbued with the blood of the reptile, after 

 which there are produced very beautiful feathers of various 

 colours. — (Edin. New Phil. Journ.) 



13. Tmning Rattle-Snakes. 



Mr. Neale, it, is said, has succeeded in America in taming 

 rattle-snakes, by means of music, so as to prevent them doing 

 any harm. This author asserts, that they really possess the 

 power of enchanting animals, or of rendering them motionless 

 through terror; for he says he has seen examples even in his 

 garden. The effluvise of these reptiles has nothing nauseous in 

 it. — (Edin. jNew Phil. Journ.)
