EPIDEMIC TYPHUS AMONG CATTLE

20///. — He feeds better, and moves about better. The swellings 
also are subsiding. Continue powders and ointment. 
Aug. 10//?, — Much improved. The enlargements are fast 
yielding to the power of the medicine. The animal is gathering 
flesh very fast, and it bids fair to be a perfect cure. 
Sept. 15//?. — Well: discontinue the treatment. 
Remarks , — Although the first case was ultimately a failure, 
I think that, had I been earlier in the field, or have pursued my 
treatment two months longer, it might have ended differently. 
The effects of the drug greatly exceeded my most sanguine ex- 
pectations. 
In the second case there was a permanent cure: and were 
there no other cases upon record, the above two satisfactorily 
prove (to me at least) that iodine is a highly valuable medicine 
in veterinary practice, and encourage us to hope that its benefi- 
cial effects may yet be extended to diseases in which we have not 
yet employed it. The person, whoever he may be, that puts it to 
the test, and records his cases, successful or the contrary, will 
confer an honour on himself and a benefit on the profession. I 
have at this time a case of scirrhous tumour in the udder of a 
mare, which shall appear (with your consent) at some future 
period.

ON EPIDEMIC OR CONTAGIOUS TYPHUS AMONG 
CATTLE.

[We are pleased that the translation which was given in the 
July number of The Veterinarian, of the distinction be- 
tween variola and contagious typhus has yielded so much sa- 
tisfaction to our readers. We were quite aware of some no- 
sological errors of the learned Professor, and much disliked 
that personal feeling with regard to another veterinarian, which 
should have no place in essays like these. 
Instead of pursuing the subject of inoculation for typhus, we 
turn back for a moment to inquire into the actual origin of this 
disease. The Professor gives an interesting and correct account 
of the origin and progress of the modern epidemics. We will 
only remark, that he here confines his attention to those aggra- 
vated forms of contagious typhus which are generated under 
the peculiar exciting causes of disease to which these cattle
