found to be inflamed ; it is gorged ; its surface marbled with green 
or yellow spots; the biliary vesicle is flabby, distended, and filled 
with thick dark bile, and traces of slight phlogosis are often per- 
ceptible. Lastly, when the urinary passages are affected during this 
disease, the bladder is sometimes empty, and occasionally distended 
by a great quantity of urine. The internal membrane is also 
slightly phlogisticated. 
Diagnosis . — This may, in our opinion, be established without 
much difficulty. In the first place, there is always inflammation 
of the nasal mucous membrane, and, however this inflammation 
may vary in its phenomena, it is still of a peculiar character. It 
acts sympathetically on the organs of circulation and digestion, 
of sense, and of motion, and thus determines fever, swelling of the 
head, ophthalmia, nasal flux, nausea, vomiting, the thick white 
covering of the tongue, the agitation, abnormal yelping or cries, 
inappetence, yellow hue and fcetidity of the urine, coma, convul- 
sions, spasms, &c. Sometimes we find symptoms that announce 
a stoppage of the respiratory passages, or irritations of the mucous 
membrane of these parts — sometimes those of a violent extra ex- 
citation of the circulatory 7 system : at others, there are those of 
encephalitis and irritation of the brain and its meninges ; whence 
arise those permanent convulsions which constitute chorea, and 
spasm of the jaws, or portions of the whole of the body, accom- 
panied by phenomena resembling epilepsy, the fits of which may 
become frequent, and paralysis of the hinder limbs, or the loins, or 
the croup, or, lastly, of both abdominal limbs at once.

A portion of a Letter from Mr. JOHN Stewart, M.R.C.S . , V.S. 
In this land of kangaroos and cockatoos I hear nothing of 
veterinarians, their sayings or doings. Your Periodical does not 
come to the colony, and I long very much to see it. I have many 
things to say which I flatter myself would be worthy of a place in 
it ; but the distance, the time, the want of correspondence, and my 
ignorance of your proceedings, all conspire to deter me from writing; 
I hope, however, to make arrangements very soon, by which I shall 
enjoy something like a regular intercourse with you in future. 
My health has greatly improved since I settled here, but my 
fortune not so much as I could wish. An honest man seems to 
have but a poor stand among them. Away from town, however,
