request, and therefore have not time to enter more fully into the 
subject. I trust, however, that you will meet with responses from 
others who have had more experience in those matters than I have, 
and who may be able to throw more light upon the subject. I can 
only say, that I shall be at all times willing, when called upon, to 
afford any information in my power to my own professional 
brethren, as well as to that profession to which I consider ours 
greatly indebted. 
CONTRIBUTIONS TO CATTLE PATHOLOGY. 
By Mr. JOHN BARLOW, V.S., Edinburgh Veterinary College. 
Observing of late in your Journal a lack of matter relating to 
the diseases of horned cattle, I am induced to send you the follow- 
ing cases, which occurred during Professor Dick’s late visit to Lon- 
don : not that they possess in themselves any thing peculiarly new 
or striking, but to convey an idea of the system here pursued, and 
the benefit which must result from entrusting out-patients to stu- 
dents, such responsibility inducing a necessity to form for them- 
selves proper opinions, their correctness or incorrectness being 
daily verified by the Professor himself. As cases of out-patients 
occur, they are placed under the immediate care of senior students, 
each taking his* turn, with whom the rest are at liberty to visit : 
his particular duty being to report daily, or oftener, as to the pro- 
gress of their patient. 
Case I. April 1th . — A cow, belonging to Mr. Swan, cow- 
keeper, Jamacia-street, which had for some weeks previously, 
according to the owner’s account, been off her feed, dull in appear- 
ance, with unhealthy skin, staring coat, and subject to occasional 
distention of the paunch, was placed under care of Mr. Tennant. 
On visiting her, she manifested the following symptoms : great 
distention of the paunch — pulse 75 and weak — breathing, of itself 
not materially impaired, but rendered difficult in consequence of tu- 
mours within the parotid glands pressing down the larynx — feeble 
cough — skin firmly adherent to the body and harsh, with rough 
coat — slight yellowness of mucous membranes — constipation — 
arched back, and pain on pressure over the right hypochondriac 
region. 
From carefully considering the nature of these symptoms, and 
taking into account the period of their continuance, we were at 
once convinced that the case was one wherein extensive disorder 
of the liver existed, with general tubercular diathesis.
