having been broken away since death. The ridges for muscular 
attachment are very prominent and the inner edge of alveolus round 
the second and third molars is thickened by the deposit of nodules of 
new bone, as though some irritation had been present during life. 
The teeth are moderately worn and have a small amount of tartar. 
No. 20. Anterior portion of a lower maxilla containing the in- 
cisors, canines, and left first bicuspid and first molar. ‘The left 
second bicuspid was lost during life, and its socket partly filled up 
by new bone. The roots of the central incisors are slightly, and 
the right lateral and canine are considerably, eroded on their anterior 
surfaces at the neck, and the central incisors are worn away almost 
to the lower margin of the enamel. There are some small masses of 
tartar upon the teeth. 7 
No. 21. Chief portion of right half of lower maxilla, containing 
four large and well-formed teeth— the three molars and first bicuspid. 
The sockets of the other teeth are in good condition, but empty, 
their former contents having disappeared since death. 
The teeth are slightly worn, and have small masses of tartar de- 
posited upon them. The first molar had its postero-internal angle 
injured during life, the enamel and some dentine having disappeared 
at this spot, but the edges of the seat of injury are rounded, showing 
that the injury was antecedent to death. The buccal surface of the 
second molar is also injured in a somewhat similar manner, though, 
as the edges are much less rounded, the injury may not improbably 
be post mortem. The wisdom tooth has also been slightly injured. 
The alveolar edge on the inner side of the second and third molars 
is thickened and rough, new bone having been deposited as the result 
of inflammation of a chronic character, while the bone on the inner 
and outer sides of the wisdom tooth is cupped from absorption 
having occurred at the same time. 
No. 22. Portion of body and ascending ramus of right lower 
_ jaw, containing the three molars. The specimen is from a young 
adult, as is shown by the wisdom tooth being but very little worn. 
‘The teeth bear some small masses of tartar upon them. Evidently 
much more existed during life, but the bulk of it has subsequently 
been lost.
