 with a plain gold ring on the third finger. The joints and 

 wrist-bones show clearly, while the faint, shadowy part 

 shows the outlines of the hand as it was held for one-half 

 minute before the camera. At upper end of third or 

 palm joint of thumb appears a small knob of sesamoid or 

 false bone. See page 357.

aboratory in Chicago.
