LAMENESS. 
Wolverhampton, who (in the fifth volume of the same journal) wrote 
a fuller and highly interesting paper on the subject, from which we 
shall take the liberty here to make a few extracts. 
Mr. Pritchard informs us he has “ several times witnessed the 
destructive affection that “ the joints are attacked with acute 
inflammation, which, by metastasis, moves from one joint to an- 
other, and from one limb to another;” and “ thinks, with M. Be- 
nand, that it arises from colts sucking the mares when they return 
from work*; from some change in the milk, probably produced by 
the exertion of the animal keeping up, for several hours together, 
increased action in circulation.” 
Never having had an opportunity of making any observations 
on this formidable disease of the joints of the young animals, we 
can do no more than refer such of our readers as may desire farther 
information to Mr. Pritchard’s instructive paper (in The VETERI- 
NARIAN for 1832). We have introduced the subject here because 
we think it comes fairly under the heading of rheumatic inflam - 
mation of the joints; of which, in point of fact, as it appears to us, 
it is a form peculiar to foal-hood. 
Ulcerative Disease of Joints. 
As far as our observations have hitherto gone, there would 
appear to be three different kinds of inflammation of joints ; viz. 
1, that which is the result of what goes by the name of “ an open 
joint,” to which, for distinction’s sake, we may apply the epithet 
traumatic ; 2, that which we have called rheumatic , or metastatic ; 
3, that which is prone to take on the character of ulceration, and 
from that circumstance may be denominated the ulcerative. Hav- 
ing considered the two former, our present affair is with the latter. 
In their investigations into the causes and nature of lamenesses 
there was between the old and modern school of farriery this essen- 
tial difference ; — that while the farriers, for the most part ignorant 
of anatomy and physiology, confined their observation to the exter- 
nal changes or alterations of parts, veterinarians, brought up in a 
knowledge of those sciences, have extended their inquiries into the 
internal structures, and have there made discoveries which, al- 
though their existence might have been casually known to some 
of their professional ancestors, were certainly not by them, as by 
us, connected with the ordinary causation of lameness. So long 
ago as the year 1828, Mr. Jas. Turner, veterinary surgeon, of Re- 
gent Street, London, discovered the cause of what is called “ groggy 
* Query . — Did these foals run with their dams at work ? and, if they did, 
had this unnatural or forced exercise of their tender joints any thing to do 
with the production of inflammation in them ?
