EPIDEMIC TYPHUS AMONG CATTLE.

sphere, which daily and rapidly extends. From this first source 
of infection, the typhus is carried to every place at which the 
infected animals halt, or feed, or drink ; and so the disease is 
soon established over a vast extent of country. It then attacks 
successively all the cattle in the province, if the march of the 
invaders cannot be arrested ; nay, even if the enemy should 
receive a check, yet the pest has been too deeply sown, too 
widely established, and it will extend from farm to farm, and 
from commune to commune, until the whole kingdom becomes 
one infected ground. 
If, then, epizootic typhus was not originally a product of our 
own country — if it appears chiefly among the cattle destined for 
the provision of our armies — if it has always arrived in France 
through the medium of Belgium, or the borders of the Rhine or 
of Italy, and at times when war has afflicted these kingdoms, or 
our territories have been attacked by foreign armies — if, start- 
ing from its original focus, it spreads successively through every 
part of the kingdom, the sanitary measures, by the help of 
which we may be enabled to oppose the march of the epizootic, 
and of which we must now treat, will comprise, 
1st. A knowledge of the agents by which the typhus is pro- 
pagated — of the means by which the threatened evil may be 
repelled, or the malady extirpated if it has begun to appear. 
2d. If it has invaded some one or more of the departments — 
a knowledge of the means by which it may be confined to this 
infected spot : or if it has reached the centre of a commune, 
those by which the stables yet sound may be preserved from the 
infection that surrounds them : such will be the course pur- 
sued in the remaining articles devoted to the consideration of 
this subject.

THE DISTEMPER OF DOGS, AS SEEN IN INDIA. 
[We are indebted for this paper to the kindness of the Editor of 
The Lancet.~\ 
Dear Sir, — If canine pathology is not beyond the pale of 
the Journal which is so ably edited by yourself and copiously 
supplied with interesting matter, may I ask the favour of you 
to give the following concise case a portion of your columns ? 
it will be interesting to the sportsman, and I hope not less so 
to the physiologist. On the first of September 1835, I was 
asked by a lady to administer some relief to her favourite dog 
Rover, a large pointer, five years old, which she thought to be
