SUPPRESSION OF SUPPURATION THE 
evening. The head only was examined : she would not permit 
any other part to be meddled with. There were three distinct 
processes or spiculse on the inner table of the skull pressing upon 
and indenting, but not perforating, the dura-mater. That mem- 
brane, however, had become slightly ossified. There were dis- 
tinct although very fragile lamellae of bone. This was the second 
instance that I had met with of ossification of this membrane. 
There was considerable congestion of the vessels of the arachnoid 
membrane, but the brain did not present any morbid appearance. 
By the irritation of these spiculee, and, afterwards, of the slight 
ossification of the dura-mater, that cerebral irritation was produced 
to which most of the symptoms related must be referred. 
After-experience, where I had the opportunity of post-mortem 
examination, proved that this habit of running round in the dog is 
chiefly or entirely attributable either to processes of the cranial bones, 
prominent or sharp, or occasionally to exotosis, and of very consi- 
derable size too, on the inner surface of the skull. Why he should 
be more subject to these irregularities of cranial surface than any 
of our other patients, I confess that I cannot explain. My first 
partner, and master in canine pathology, used to refer this disposi- 
tion to turn round to spasmodic cholic ; “ for,” says he, “ however 
the head may be connected with the disease, the nervous affection 
is spent on the intestinal tissues. The most attentive dissection 
of the head, in these cases, has never detected any morbid appear- 
ances there.” I must, with all due and sincere deference, enter my 
protest here. 
In every case of this turnsick — if I may so term it, from its re- 
semblance to a disease bearing that name in sheep — I have found 
satisfactory morbid appearances within the cranium. The brain is 
the organ first and principally affected — the morbid state of the 
bowels is merely accessory. 
ON THE SUPPRESSION OF SUPPURATION CONSIDERED 
AS THE CAUSE OF CERTAIN MORBID PHENOMENA.

tion, may be pleasantly and usefully compared with the essays 
of our talented friend, Mr. Pritchard, now in the course of pub- 
lication in our Journal.] 
Among the causes of those diseases, so frequent, so serious, and 
so often compromising the lives of our patients at the close of long 
and copious suppuration, there is one of great importance, and
