LAMINITIS. 
YI.— Etiology .—Laminitis has been attributed to many and 
the most varied causes, and, ainoDg others, has now been ascribed 
to a traumatic origin, consisting of injuries of the foot; and 
again, to internal lesions, resulting in the inflammatory process 
which is characteristic of the affection. 
The external traumatic injuries, which it is claimed are those 
chiefly instrumental, are on the contrary, of very rare occurrence 
as causes of the disease. Our observations agree with those of 
H. Bouley, and if there is a traumatic causation for this disease, 
or, at least, one identical with it in respect to symptoms and 
primitive lesions, it is nevertheless, certain that its progress is 
very different; there is found with it an evident tendency to 
suppuration instead of exudation, and there is no such formation 
as the chronic process which is found when laminitis is due to an 
internal phlegmasia. 
It has been said in reference to the action of the heated shoe 
upon the hoof, the percussion of the blacksmith’s hammer and 
the pressure of the shoe and of the nails upon the living tissues, 
that all these causes together must, as their sure effect, make the 
foot tender, and stimulate in its constituting structure, the conges-
