DISCOVERY OF THE SKELETON. 7 



happily and successfully completed after an unremitting labor of nearly 

 four weeks. ( Vide Large Plate.) 



The principal changes were the depression of the head, in consequence 

 of which the height of the skeleton was diminished, — an increase in the 

 curve of the spine so as to elevate the middle dorsal vertebras much 

 above the anterior, and thus to give to the dorsal portion of the vertebral 

 column the form of an arch, with an upward convexity and downward 

 concavity, — a change in the position of the tusks, so that their convexity, 

 instead of looking outwards, was directed downwards and backwards, their 

 concavity forwards and upwards. 



After the skeleton had been satisfactorily arranged, it was exposed 

 for three days to scientific persons, and such other individuals as had the 

 curiosity to examine it ; then removed, to be again set up at the request 

 of the distinguished geologist, Sir Charles Lyell, who happened to arrive in 

 Boston at that time. Before being once more dismounted, it was examined 

 by Professors Horner and "Wyman, and by the illustrious philosopher, 

 Professor Agassiz. It has since been set up, under my direction, by 

 Mr. Ogden, with important improvements, and is now deposited in a fire- 

 proof structure erected for its reception in Chestnut-street, Boston.
