of the molars of the left side and the consequent absorption 

 of the bone. In spite of this absorption, the angle of the 

 jaw is very sharp, approaching a right angle. The loss of 

 these teeth, and the resulting absorption, was probably due 

 to an excessive deposit of tartar. The teeth remaining in the 

 jaw bear such a deposit, and in some instances are deeply 

 eaten into. The socket of the first bi-cuspid on the same 

 side, the left, has been the seat of an abscess, and, as a conse- 

 quence, is greatly disfigured and enlarged, even encroaching 

 upon its neighboring canine. On the right side, the second 

 molar cavity also shows the ravages of this disease, while its 

 accompanying molar is deeply eaten into at the base of the 

 roots. The cavity of the wisdom tooth does not indicate a 

 fully-developed tooth, thus aiding in estimating the age of the 

 specimen. The right canine is remarkable in having two 

 distinct roots. 



The eighth rib of the right side was broken nine cm. from 

 its anterior end, but has united by the formation of a false 

 joint. 



The femurs, tibiae, and fibulae show some interesting 

 pathological features, all of which are more marked upon the 

 bones of the right side. The marks being bi-lateral, indicate 

 some blood disease as their cause. 



The disease attacked the right femur about the center of 

 the shaft, after the manner of rarefying osteitis, to an extent 

 of about 16 cm., while marked deposits were made on both 

 of the condyles. The left femur is only slightly injured, and 

 then somewhat lower on the shaft than in case of the right 

 femur. 



The right tibia and fibula are the seat of the worst ravages. 

 In the former, about 9 cm. below the turbercle, the enlarge- 

 ment is quite prominent on the crest, but is principally found 

 on the internal surface. Below this, some 8 cm., and situated 

 on the crest, is a small but interesting case of rarefaction. 

 One of the most prominent cases of osteitis appears on the 

 ridge between the posterior and external surfaces. However, 

 about the center of the shaft it spreads to both these surfaces, 

 and finally, near the lower extremity, covers the entire external 

 surface. The popliteal line is almost obliterated by this bony 

 deposit. The entire lower extremity of the bone is diseased.
