considerable quantity was found adherent to the pleura covering 
the ribs and lungs, forming false membranes between them. There 
was also a quantity of serum in the chest. The lungs, although 
somewhat compressed by lymph and fluid, were sound, with the ex- 
ception of one portion containing tubercular deposit. 
Although this case eventually terminated fatally, still, had not 
the animal so materially exhausted himself in ineffectual attempts 
to rise, judging from the amendment which had till then gradually 
taken place, there is every reason to believe recovery would ulti- 
mately have supervened. The very evident mitigation of the 
symptoms during the time iodine was administered proves, as nu- 
merous other trials under similar circumstances have done, that 
this medicine, given in sufficient doses, is, under proper precautions, 
a most valuable one in the management of what are ordinarily 
considered intractable sequelae of pleuritis, pericarditis, and influ- 
enza. In the post-mortem investigation of this case, great care was 
taken to inspect carefully the stomach, kidneys, liver, &c., in order 
to see if any of the structures of these organs had in any way suf- 
fered from the large quantity of iodine the animal had taken : there 
was not, however, any appearances denoting such to have been 
the case. It is worthy of remark, that the serum in the chest was 
remarkably pure and transparent. 
In last month’s report it was noticed that the vesicular epizootic 
among neat cattle was again making its appearance in this neigh- 
bourhood. During most of April it prevailed extensively, and, 
although only thirty-eight cases are noticed, a much greater num- 
ber came under observation. Considerable attention was paid to 
the disease in order to endeavour to establish the means of its 
propagation, and it was found that, in very many instances, it mani- 
fested itself in stocks of cattle which had not the slightest com- 
munication with others : so that, whatever may be its contagious 
properties, it is sufficiently evident that its propagation is far from 
being dependent upon them alone, but is due also to atmospheric 
agencies, which, it must be believed, are one great class of causes 
originating all epizootic diseases. It is impossible, then, by 
adopting many of the precautions at present had recourse to, that 
this or other epizootic diseases can be arrested, seeing that the 
great excitant is beyond the controul of any means that man can 
use to obviate its action. 
The three fatal cases of enteritis in cattle occurred in animals 
that were in contact with those suffering from the epizootic; but 
in the cases referred to the disease did not make its appearance in 
any thing like the form it usually assumes. No soreness of the 
mouth or feet was observable in any of them ; symptoms of ente- 
ritis, with considerable debility and low fever, however, appeared
