ON THB BONES pF THE MASTODON. 361 



rings, similar to those observable in fossil ivory, but the figures have 

 been subsequently filled by a ferruginous or spathic crystallization. I 

 have not been able to discover those lines, disposed like lozenges, 

 which characterize so distinctly the ivory of the elephant. 



Notwithstanding the correspondence existing between this tusk and 

 that of the hippopotamus, its hollow is not the same ; however, it is 

 plain that the narrow- toothed mastodon bore a resemblance to this 

 animal in this particular, as well as in the division of the protuberances 

 of its jaw-teeth into trefoil shapes. 



Fresh discoveries have recently been made of the spoils of this 

 animal in Tuscany. 



The Chevalier Fossombroni, minister to his Highness the Grand Duke, 

 as profound a philosopher as he is a virtuous and enlightened states- 

 man, has sent me a drawing representing a considerable portion of the 

 jaw, with a tooth of eight denticuli, perfectly distinguishable. 



This specimen was discovered by some peasants at BettoUi near the 

 summit of a small acclivity springing from the centre of the valley of 

 Chiana, a country where the name of M. Fossambroni will be immor- 

 tal. It was two feet deep in a bed of sand stone, supposed to be marine, 

 which was interspersed with shells of a very adhesive quality. The 

 enamel of the tooth is of a grey colour and very hard. It will be ob- 

 served, that Bettolli is very near Mount Follonico, where Baldassari 

 found the jaw which he described in 1767, in the Memoirs of the 

 Academy of Sienna. 



Between those two places lies Asina-Lunga, where in 1815 Dr. 

 Giuli found two jaws of the same species, which he too has presented 

 to the Academy of Sienna. Hence, we cannot entertain the slightest 

 doubt of these animals having been numerous in the Valley of Chiana, 

 at the period when the districts at present forming the territory of Tus- 

 cany were inhabited by hippopotami, the rhinoceros, and the elephant 

 of the old world. 



It would be most desirable that excavations conducted with intel- 

 ligence might bring to light, from the bosom of the earth, the remain- 

 ing bones of so remarkable a species, which must undoubtedly exist not 

 far from the jaws. We might then be enabled to reproduce this animal 

 entire, as we have done with the hippopotamus of the Valley of the 

 Arno, and the rhinoceros of Parma. This would be a new service ren- 

 dered to science by Tuscany — that science which is at present so 

 deeply indebted to her. 



Another Addition. 



The researches daily made in Tuscany are a more than sufficient 

 proof how very classical that country is, in the history of fossil 

 animals. 



A discovery has just been made there of the almost complete skele- 

 ton of a narrow-toothed mastodon. Professor Nesti of Florence is at 

 present engaged in preparing a description of it. This will form a 

 most important document in this line of research, and I shall lose no 

 time in laying its contents before my readers, as soon as it shall have 

 appeared. The bones of this mastodon are likewise found in Poland. 



M. Bojanus, a celebrated anatomist and professor at Wilna, has just
