blood. The synovial membrane was much thickened at the 
parts most vascular; then again these same structures in 
other joints were much paler than natural. The periosteal 
covering of the long bones was quite vascular and easily de¬ 
tached, especially the bones of the skull. Some of the flat 
and irregular bones were soft and could be readily cut with 
the knife. One very noticeable feature being that all liga¬ 
mentous and tendinous attachments were easily separated, 
bringing portions of bone as they were torn loose. 
These attachments were much discolored, indicating that 
local inflammation or extravasation of blood had taken place.. 
I am of the opinion that there must have existed considerable 
inflammation in the soft structures affected, and was sufficient 
cause for the manifestations of lameness which existed in 
certain articulations. Another post-mortem characteristic is, 
that the weight of the bones is greatly diminished, apparently 
one-third their weight being lost. The increased size of the 
medullary canal is well marked in the long bones, and what 
seems to be a complete breaking down of the cancellated 
structure is visible throughout. The same degree of destruc- 
' tion exists in the compact tissue. The hauersion canals, the 
lacunas and canaliculi appear as homogeneous. 
Another noticeable feature of this disease presented itself 
while cleaning the bones—perhaps due to their extreme soft¬ 
ness—the different processes (epiphyses) were detached from 
the bone. The application of the slightest force upon a tendon 
or ligament was sufficient to effect their removal. Contrasting 
a healthy bone with one affected with this disease, we observe 
that at the ends of the long and flat bones the disease has 
permeated the compact as well as the cancellated structure. 
The increased size of the hauersion canals is very patent, as is 
the formama for the passage of the blood-vessels. The 
same exists in the periosteal membrane, causing the bone at 
the extremities to assume a honeycombed appearance.. 
Thus I might proceed at length to narrate post-mortem 
lesions, believing, however, that a few briefly stated facts will 
prove more interesting than a paper treating at length on all 
the details. From all sources obtainable in the literature
