The most common form of anthrax in P & f , 
characterised bv erysipelatoid eruption, specimens of whi

cherry-red hue of the skin appears generally as a widish> bms

and inner surfaces of the thighs; the parts so coloured ar

the tarry condition of the blood and the engorgement (per¬ 
haps post-mortem) of the vessels of all sizes and paits, but 
especially in the neck and head, as seen on decapitation, so 
as to give a dark appearance to the muse es, and even o 
changlthe fat to a disgusting grey mass. This 'condition o 
the blood, and the unvarying tendency of all the tissues 
to rapid decomposition, are characteristic of anthrax. The 
spleen in the few cases where I have been able to get a look 
at that organ (for the viscera are generally made away with as 
early as possible) is not, however, dark and hypertrophied as 
in the anthrax of cattle. Sometimes the erysipelatoid blush 
extends to a universal redness of the entire surface, so as to 
account for the use of the term “ scarlatina, which disease 
, first sight closely resembles. In such cases as the above 
the fat beneath the skin is usually pink in colour, which ap¬ 
pearance continues after death, as certain specimens m my 
possession show. I believe that this disease is not scarlet 
fever—first, because the examples I have seen of it have 
occurred in herds affected with other forms of anthraxj 
secondly, because in the cases I have observed there has not 
been any special throat lesions, such as are pathognomonic 
of ordinary scarlet fever in man ; and, thndly, because 11 
some of the cases where I have been able to examine the 
intestines, lesions characteristic not of scarlet fever but of 
anthrax have been found. . . P , . 
With the exception of the cases presently to be referred to, 
so far as my experience goes, there have been no abscesses, 
tumours, spots, parotid enlargements, or intestinal ulcers in 
anv of the eases, but the disease is evidently highly contagious, 
i have neither regarded it as scarlet fever nor ordinary
