Florence, 20t?t May, 1859. 



The Florence Museum also contains a palate specimen of a young 

 Rhinoceros Etruscus, showing on the right side the four milk molars 

 emerged, of which the first three are very slightly affected by wear, 

 the fourth is hardly emerged from the gum, and is in a state of germ. 

 The second and third have each a small intercolumnar tubercle, but no 

 basal cingulum sweeping round the inside of the barrels. On the left 

 side there are only the first and second milk molars, with the anterior 

 part of the third.
