Pizarro. 



thirty to forty years old, drowned in crossing the Delaware during the 

 spring of 1847, is in my possession. The teeth in this head are eight in 

 number, and arranged in the following order : In the lower jaw, on the 

 right side, fully developed, in place, is a tooth measuring seven inches and 

 three-fourths in length, and two inches and three-fourths in width, con- 

 taining ten perfect ridges, and an anterior space from which others have 

 been worn away. This constitutes the fourth tooth of the series. Behind 

 it lies imbedded in its socket an undeveloped tooth, exhibiting a surface 

 of three inches and a quarter only. A large portion of the tooth is still 

 imbedded in the base of the condyloid process, and presents eight visible 

 ridges with a superficial concavity opposed to the convexity of the tooth 

 in the upper jaw. 



The teeth in the upper jaw correspond with those in the lower, being 

 on each side one in place, and one undeveloped ; the former measuring eight 

 inches in length by three inches and a quarter wide, and containing eleven 

 ridges. Behind this lies another undeveloped, and, in a great measure, 

 buried in its bony socket. 

 Elephant In the Museum of Moses Kimball, Esq., of this city, there is a most 



perfect and beautiful skeleton, prepared and correctly set up by the inge- 

 nuity and skill of Dr. N. B. Shurtleff. The animal was known by the name 

 of Siam. About two years since, it died on the banks of the Mississippi, 

 was transported to and prepared in this place, and was thought to be 

 of advanced age. I should judge, however, that it was between thirty and 

 forty years old at the time of its death. In the head of this animal, there
