DISEASES OP THE UDDER AND TEATS IN COWS. 507 
neck more predominant, with the copious discharges from the 
nostrils and mouth of the yellow jelly-like lymph ; and here, 
I imagine, nature had force sufficient to contend with the 
disease, and the vessels had relieved themselves by such ex- 
travasation and effusion ; and these cases were always most 
easily dealt with, and rarely, I may say, ended fatally, by 
keeping in view, in treatment, the cause, and also attending 
to the local and topical indications. The malignant, and too 
often fatal, form, is that in which the general congestion and 
shock to the system is such, that the vis medicatrix naturae 
has not power enough to cope with the disease ; these cases 
are sometimes fatal as early as in from an hour to two from 
the commencement of the attack. 
The peculiar pathological character of this epidemic, and 
its great fatality, have invested it with much interest in my 
eyes, and 1 could enlarge much on its symptoms and pecu- 
liarities, were I not afraid of having already run to an 
unpardonable length in this letter. If, at any future time, 
you should assure me that I have not taxed your time and 
patience beyond bounds, and you have not set me down as 
too prolix a correspondent, I shall be too happy to add 
further particulars from my case-book, should this disease 
possess any of the interest in your eyes which it does in mine. 
I am, my dear Sir, 
With much respect and regard. 
Yours very truly, 
Vincent Nelson, V.S., H.E.I.C.S. 
*** Full of interest as this disease must be to an Indian 
V.S., it possesses many novel and strange features to us, 
concerning which we hope Mr. Nelson will one day enlighten 
us again out of his Case Book. — Ed. Vet. 
ON DISEASES OF THE UDDER AND TEATS 
IN COWS. 
By Mr. W. A. Cartwright, M.R.C.V.S, Whitchurch,

Case \ .—Obstruction in a Cow’s Teat .— In 1831 I was 
called in to attend a cow, the property of Mr. Tudman, of 
Yoking’s Gate, near this town, that had calved a week ago, 
and had borne two calves before. There was an obstruction 
up one of the teats, and the udder was very much distended 
with milk. I merely introduced a knitting needle up it for
