Original no. 23 (from Dawson mound no. 6): Pieces of upper and 
lower jaws of a male skull. The only feature of interest consists in 
the greater size in both length and breadth of the third right lower 
molar than of either the first or the second. 
Original no. 27 (from Dawson mound no. 6): The front of a male 
adult skull. The bones are somewhat less in thickness than the 
average in the Indian. 
The upper jaw has a well-formed arch, moderate alveolar prognath- 
ism, and sixteen normal teeth. 
The lower jaw also has a regular arch and shows some prog- 
nathism. The third molar on the left side was lost very early, or 
more probably never appeared, though there is sufficient space for 
it. Anteriorly, this jaw shows a rare and interesting dental anomaly 
(fig. 20). Ventrally and midway between the bicuspids, both of 
which are positively second dentition teeth, there is on each side 
another dental element. On the right side this is quite fully erupted, 
nearly as high as the bicuspids and resembling these in the shape of 
the crown, though somewhat smaller; on the left side a similar tooth 
is just appearing. There are no diastemae between the lower teeth 
and there is no visible cause for the extra bicuspids.
