surfaces of all the bones, and particularly so in that 

 part of the bone where the greatest amount of 

 spongy tissue existed. Their extremities were 

 greatly increased in their transverse diameter, their 

 shafts were not much affected in this way, present- 

 ing after divestment a pinkish hue. Upon pressure 

 being applied ever so slightly bloody fluid would 

 ooze from the bony substance, which when the 

 pressure was released would recede again into the 

 tissue showing the porous condition which existed. 

 To the touch they were soft, velvety, elastic and 

 slightly rebounding. The articular cartilages were 

 somewhat discolored but all intact in this particular 

 subject, which probably accounts for the absence of 

 lameness other than that to which I have already 

 alluded. In these cases showing continual, decided 

 lameness, the cartilages will be found not only 

 discolored, but removed by absorption in part or 

 wholly. A section made into a long bone at its 

 most affected part, which was done with little resist- 

 ance, showed the canal somewhat increased trans- 

 versely, with its contents of a reddish, watery char- 

 acter. The haversian canals and cancelli were in 

 some instances obliterated, with their traversing 

 blood vessels excessively engorged, while the 

 lacunae and canaliculi were filled with a light yel-

 periosteal foramena were dilated and the periosteum
