NOTES TO BOOK XVIII. 



(Y.) p. 541. AUGUSTINE SCILLA'S original drawings of 

 fossil shells, teeth, and corals, from which the engravings 

 mentioned in the text were executed, as well as the 

 natural objects from which the drawings were made, were 

 bought by Woodward, and are now in the Woodwardian 

 Museum at Cambridge. 



(z.) p. 561. Among the many valuable contributions 

 to Palaeontology in more recent times, I may especially 

 mention Mr. Owen's Eeports on British Fossil Reptiles, 

 on British Fossil Mammalia, and on the Extinct Animals 

 of Australia, with descriptions of certain Fossils indicative 

 of large Marsupial Pachydermata : and M. Agassiz's

 on the Fishes of the London Clay. All these are contained 

 in the volumes produced by the British Association from 

 1839 to 1845. 



A new and most important instrument of palseontolo- 

 gical investigation has been put in the geologist's hand 

 by Prof. Owen's discovery, that the internal structure of 

 teeth, as disclosed by the microscope, is a means of deter- 

 mining the kind of the animal. He has carried into 

 every part of the animal kingdom an examination founded 

 upon this discovery, and has published the results of this 

 in his Odontography. As an example of the application 

 of this character of animals, I may mention that a tooth
