consideration of these serious symptoms, was ultimately de¬ 
stroyed. 
On removing the leg from the trunk, at the post mortem, 
numerous purulent collections were found in the axilla, the 
shoulder being surrounded by a large, hard, grayish colored 
swelling on both surfaces. All the external scapular muscles 
were involved in it, and had lost their coloration, becoming 
pale and containing numerous small purulent centres; the 
sub-scapularis muscle on the inside presenting the same ap¬ 
pearance. On maceration, the scapula appeared to be sur¬ 
rounded by an osteo-cartilaginous muff, and constituted a 
true sequestrum, entirely surrounded or invaginated by the 
newly deposited bone on its outer surface. 
According to the authors, the following should be the 
general process followed in the formation of this pathologi¬ 
cal specimen: 
ist. A traumatism of medium severity, received on the an¬ 
terior border of the scapula, penetrating the enveloping skin 
and muscles. 
. <• 
2d. An insignificant wound of the skin. 
3d. Suppurative ostitis, consequent upon the traumatism, 
forming on the bone, at the injured or contused spot, with 
separation of the periosteum and formation of an areolar tis¬ 
sue of new formation. 
4th. The increase and extension of the suppurative osteitis, 
which, instead of remaining limited, gradually enlarges and 
spreads until the scapula becomes isolated and surrounded 
with a new layer of bony tissue. 
5th. The scapula becomes necrosed and forms the seques¬ 
trum, in consequence of its deprivation of the blood neces¬ 
sary to its nutrition. 
6th. The purulent collection in the muscles and new sur¬ 
rounding structure was the consequent result of the excess of 
the inflammation, which in a reduced degree might have been 
followed by a comparative recovery .—Recueil de Med. Vet,
