LAMINITIS. 
III. Pathological Anatomy. At the initial period of lamini- 
tis, when there is only simple congestion of the keratogenous 
apparatus, and especially of the podophyllous tissue, the sub- 
horny tissues are in a condition of sanguineous derangement, 
characterized by objective signs. When the hoof covering them 
during life is removed, they are found of a dark red color, in a 
kind of eythema. When pressed between the fingers, their 
thickness is noted to be increased, and they are found to be 
gorged with blood, an incision made through them allowing the 
escape of a large quantity of that fluid. 
If the laminitis exists for several days, the podophyllous 
tissue is found to be infiltrated with plastic exudations, and if 
there has been hemorrhage or apoplexy, blood is found between 
both the sensitive and insensitive laminae. In other cases there 
is pus, and in case of gangrene, the tissues are found of a livid 
color. 
The alterations are still more serious in cases of chronic 
founder. When a foot, foundered for some time, is divided by 
the saw in its antero-posterior axis by a section of all the parts,
