LAMINITIS,, 73 
although there was laborious respiration. L think otherwise. 
It w T as “ idiopathic” laminitis. 
I recollect another case in a cart-horse. He broke loose in 
the night, and ate a large quantity of oats, and in a few days 
after, had laminitis ; but it was not to say severe. 
I have also seen chronic cases in indolent, fat cobs and 
ponies, which were ultimately obliged to be destroyed for 
having become pumiced-footed. 
Cases of pneumonia are not so common now as they were 
formerly; and I cannot say, although I have seen hundreds 
of cases, that I ever saw a case of laminitis consequent on that 
disease . 
I have also seen a vast number of cases of enteritis, but I 
cannot call to mind that I ever saw a transfer of that disease to 
the foot , so as to produce laminitis . Indeed, chronic enteritis, 
in country practice, is very rare ; and the acute is often fatal, 
from the quackery going on before we are called in. 
In conclusion, from what I have seen, and what I think, 
I am more inclined to believe that laminitis is generally 
“idiopathic;” yet that it is occasionally produced by some 
disease or cause in the stomach or bowels. I cannot say, 
from my own experience, that inflammation is ever transferred 
from the lungs to the foot, but I am sure that pneumonia is 
sometimes brought on by laminitis ; indeed, the lungs, as you 
know full well, generally suffer from all inflammatory attacks. 
I cannot positively deny it transference from the lungs to the 
foot. 
Most authors agree with you, I fancy. 
It is an important point, and we shall hear more about it ; 
but I am inclined to think G. is not far wrong. (See 
66 Vet” Vol. xvii, p. 142.) 
I am, Sir, 
Yours respectfully,

To the Editor of The Veterinarian . 
Dear Sir, — I have always considered that laminitis was 
one of the sequences of pneumonia, and I have had cases 
which I considered to be so. Is it because the mucous 
membranes are principally involved in pneumonia that the 
conclusion is to be drawn that we are not to have laminitis as 
a consequence. I refer you to the case of laminitis recorded 
by me in the Veterinarian , where it followed an abortion, and 
xxvii. 10
