After the laborious task of mending the ribs 

 and other bones, and putting together the frag- 

 ments of the head (of which no other idea could 

 be formed than appears in the skeleton), it re- 

 mained to determine the number and situation 

 of each kind. The three setts were kept dis- 

 tinct ^ out of the two collections which were 

 most numerous it was intended to form two ske- 

 letons, by still keeping them separate, and filling 

 up the deficiencies in each by artificial imita- 

 tions from the other, and from counterparts in 

 themselves. For instance, in the first skeleton 

 the under jaw was formed from this, which is 

 the only intire one we have ever heard of, al- 

 though we have seen considerable fragments of 

 at least ten different jaws ; v/hile on the other 

 hand, the upper jaw of this animal, which was 

 found in the extreme of decay, was completed, 

 so far as it goes, from the more solid fragment 

 in the former skeleton. Several feet-bones in 

 this skeleton were made from that ; and a few 

 m that were made from this. In this the right 

 humerus being real, the imitation for the left one 

 was made with the utmost certainty ; and the 

 radius and ulna of the left leg being real, those 

 on the right side followed in course. The col- 

 lection of ribs in both cases was pretty intire ; 

 therefore, having discovered from a correspon-
