246 ON THE PRESENT EPIZOOTIC AMONG HORSES. 
are sometimes observable on the Schneiderian membrane of the 
septum, and also on the buccal membrane of the mouth. In 
others the nasal membrane presents a number of scarlet streaks 
resembling those seen in the mildest forms of scarlatina. The 
discharge from the nose, when any is present, is, however, but 
seldom of a decidedly purulent character, although that from the 
eyes is frequently so. The sublingual region, when felt, may 
sometimes be observed to be slightly tumid. The manner in 
which the integuments and subcutaneous cellular tissue are 
affected, however, varies much in different individuals. Some- 
times the entire surface of the body is covered with a rash, re- 
sembling hives, or what is commonly called “flying surfeit at 
others there is a general anasarca ; but more usually the oedema 
is confined to the legs, which are often so sore and tumid, that 
in some instances the animal can scarcely move without consider- 
able pain, and is yet suffering so much from irritation that he 
cannot remain for any length of time without shifting or varying 
his position. Many instances are met with where the skin has 
become much glossier than usual ; while in others, as I have 
already mentioned, it is so tightly drawn over the body as to ren- 
der it impossible to pinch it up from the surface ; or, in common 
parlance, the animal is “ hide-bound.” 
With respect to the pulse, its character varies much in differ- 
ent individuals labouring under this affection ; depending in a 
great measure on the natural irritability of the patient, the extent 
to which the disease has influenced the system, and the varieties 
of its complications, from organs having, previously to the attack, 
been rendered susceptible to participate in its consequent de- 
rangement by the existence of chronic disease, or impairment of 
function resulting from an antecedent malady — as in cases of 
pulmonary, hepatic, renal, or other visceral affections of long 
standing. Under such circumstances, in addition to the accele- 
rated pulse, there are also present the other symptoms peculiar 
to idiopathic diseases of these organs. These extensive additions 
to the derangement of the animal system, produced by the pecu- 
liar action established in it by the presence of epizootical disease, 
ought not, however, to be confounded with the pathological his- 
tory of that affection, but be considered in their true light of 
being merely accidental complications, and not true varieties of 
the disease itself. In most instances, however, there is an accele- 
ration of the pulse. It ranges from about forty to eighty ; in 
some cases strong, in others weak. In fact, there is nothing 
varies more than the state of the pulse, even among a number of 
cases where all the other symptoms bear a close resemblance in 
each. I have lately met with several instances where, after the
