Annales du Museum, vol. V., and in the Recherches sur les 

 Ossemens Fossiles, vol. IV. first, ed. The original plates and 

 description of M. Bru are not, with the exception of PI. I., to 

 be procured in this city, and that part of the second edition of 

 the Ossemens Fossiles, which relates to the fossil Edentia, if 

 published, has not yet reached us. 



Restoration of part of the lower jaw. 



A and B (see PI. VIII.) formed one continuous piece. Of 

 this there can be no doubt, as the edges of the fracture, 

 though very irregular, correspond perfectly with each other. 

 These two portions compose the greater part of the right side 

 of the lower jaw, and contain parts of the sockets of all the 

 four molar teeth. 



The plate represents two views of the jaw as partly restored, 

 reduced to one fifth their natural size. Fig. 1. is an oblique 

 view of the inside of the jaw. Fig. 2. a profile of the outside. 

 The dotted line represents the part supposed to be broken off. 

 For accurate drawings of these, I have to return my thanks 

 to Mr. Inman, Draughtsman to the Lyceum. 



C also belongs to the lower jaw. It consists of the anterior 

 part, comprising the symphysis, with part of the elongation, 

 and parts of the sockets of the two first molars. It has been 

 continuous with B. This will be made more apparent when 

 we come to the comparison with the skeleton of Madrid. 



D (not in the plate,) is a fragment of the left side of the 

 same jaw. This is evident from its containing parts of the 

 sockets of the two last molars, part of the opening for the pas- 

 sage of the maxillary vessels, and the origin of the ascending 

 branch of the jaw. 



The teeth had fallen out of all the sockets except one, 

 which contained the body of the second molar with the crown 

 and fangs broken off, apparently by recent violence. I 

 attempted therefore to find the places of the four remaining 

 tppth. Two of them I percpiveH to b<* alike in all respects
