After the laborious task of mending the ribs and other bones, and putting together the fragments of the head (of which no other idea could be formed than appears in the skeleton), it remained to determine the number and situation of each kind. The three setts were kept distinct; out of the two collections which were most numerous it was intended to form two skeletons, by still keeping them separate, and filling up the deficiencies in each by artificial imitations 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 entire one we have ever heard of, although we have seen considerable fragments of at least ten different jaws; while 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 in 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 collection of ribs in both cases was pretty entire; therefore, having discovered from a correspondence between the number of vertebræ and ribs in both animals, that there were nineteen pair of the latter, it was only necessary in four or five instances where there was not a complete pair, either to make an artificial counterpart, or to take the same formed rib from the collection found at Captain Barber’s. In this manner the two skeletons were formed, and are in both instances composed of the appropriate bones of the animal, or exact imitations from the real bones in the same animal, or from those of the same proportion in the other: Nothing is imaginary, and what we do not unquestionably know, we leave deficient; which happens in only two instances, the summit of the head and the end of the tail.
