slaughtered, and the disease found to exist. It is astonishing to 
what an extent this disease may exist in an animal without causing 
its death ; for frequently I have seen nearly the whole surface of 
the pleura costalis, and the pleura pulmonalis in a lesser degree, 
and also the peritoneum, mesentery, and omentum, covered with 
these tubercles. They are more frequently found on the pleura 
costalis, and in greater clusters, actually lying one on another, from 
the size of a pin’s head to that of a walnut, and many are pendu- 
lous. Sometimes they assume more of a solitary character, and 
are dispersed one here and there, as on the omentum and mesen- 
tery, leaving the intervening spaces beautifully sound. 
I have seen, in some few cases, as much pleura and peritoneum 
containing these tubercles peeled off as would fill an imperial 
bushel measure. Sometimes the substance of the lungs contains a 
great quantity of these tubercles, but not generally. The tubercles 
are, if of much size, of a yellowish colour and of a cheesy consist- 
ence, and somtimes feel as if spiculae of bone was in them. In a 
similar case to the present, Mr. Morton, of the Veterinary College, 
analyzed some of these tubercles, and found them to consist of the 
phosphate and carbonate of lime, with a little magnesia. It would 
appear that this disease, in a great measure, has its seat on or un- 
der serous surfaces, such as the pleura, peritoneum, and tunica 
arachnoidis. In this instance they certainly extended into the 
sulci between the convolutions of the brain ; and, if so, we must 
conclude that they were formed on the pia mater, unless we admit 
that the arachnoid membrane extends into these depressions, which 
is contrary to the opinion of anatomists. I have never before 
examined the brains of animals that have been “ graped” in the 
chest and abdomen, but will do so the next opportunity ; and it is 
highly probable that the brain, being affected and pressed on, may 
be the principal cause of their not improving in condition. 
From the foregoing observations, I think we may infer that it is 
highly improper to rear calves from cows that are supposed to have 
this tubercular disease, or, indeed, that are affected with any chronic 
disease; as the probability is, that, after keeping them for a long 
period at expense, they may die and disappoint us at last.

The second annual meeting of this club was held at the latter 
end of February. In the morning there was a ploughing match 
in a field about a mile from the town, where a number of farmers
