conclyloideum laterale). On the articular surface, besides the 
polished and flattened surface near the posterior and inner 
margin considered above as reciprocal to a similar surface at 
the posterior extremity of the articular surface on the femur, 
is a pear-shaped arosion at the juncture of the middle and pos- 
terior thirds with its larger part externally and narrow stem 
extending internally. 
This area measures 1.5 cm. antero-posteriorly in its broad- 
est part and extends transversely completely across the face 
of the facet. At its deepest part it is i mm. below the joint 
level. Its longitudinal striae already mentioned are very dis- 
tinct and correspond with those described on the lower end of 
the femur and shown in the same figure. 
The internal tuberosity and articular surface are missing. 
Thev would probabl}' show no changes, as there are none on 
the corresponding internal condyle of the femur. The patella 
is normal. 
The few slight changes thus considered as due to rheuma- 
toid arthritis are such as are frequently seen in the bones of 
old people, and are of such limited extent that outside of an 
occasional "rheumatic" pain in the knee-joint or unpleasant 
twinge of the great toe, they probably offered very little or no 
inconvenience to the original possessor. 
In an article in the Popular Science Monthly of March, 
1903, Prof. Williston speaks of the skeleton as presumably — 
I think he used that term — that cf a woman. Tliere is no bet- 
ter evidence than the pelvic bones, and as the symphysis pubis 
and part of one descending ramus and all of the other are pres- 
ent, the subpubic angle is readily determined to be decidedly 
acute, or of the male type, and entirely lacking the obtuse or 
rounded character so distinctive of the female.
