when the feet are beginning to inflame, the animal stands uncom- 
fortably, drawing the limbs together, or jerking them up suddenly 
under the body, arching the back, and pawing; the movements 
are reluctantly performed, and the coronets hot and sore. There 
is also slight constipation, and, if with a milch cow, the secretion 
of milk is gradually diminished, and that fluid assumes a yellow 
tint; in the majority of cases it is nearly or altogether suspended. 
The udder becomes red and tense when it is involved, and the 
teats swollen and painful to the touch. This stage usually lasts 
from twenty-four to forty-eight hours, according to the intensity 
of the fever. 
Second Period .—After the time above mentioned the eruption 
begins to appear in those parts which are to be its seat, and the 
fever commences to abate in many cases. When the mouth is 
chiefly affected there are seen on its lining membrane, and partic¬ 
ularly on the upper lip, gums and sides of the tongue and palate, 
white or yellowish-white blisters, the size of a grain of mil¬ 
let to that of the size of a pea or nut, their form being very 
irregular. Sometimes they are discrete, or scattered over the 
surface; in other cases they are confluent, collectively forming 
patches which are at first gray or yellow, and afterward white; 
slightly convex; each vesicle is usually circular; the smallest are 
seen on the muffle. In the mouth they are largest, and most fre¬ 
quently confluent; bnt there they only exist for a brief period, 
the friction caused by the movements of the tongue tearing them; 
the epithelium is detached in flakes of variable dimensions, leaving 
unhealthy ulcers or denuded spots, or “ erosions ” of a bright red 
tint, which contrasts markedly with the gray hue of the surround¬ 
ing surface. These shreds are often seen adhering to the border 
of these sores; and if on the tongue, that organ is kept continually 
moving to get rid of them, and the animal emits a smacking 
sound with its lips. At this stage of the disease the papillae of the 
tongue are congested and prominent. Where there is no friction 
the vesicles do not rupture within one or two days. On the udder 
the vesicles are somewhat different. The teats are most frequently 
their seat , and it is not unusual to find the phlyctenae grouped in 
a circle around their orifice; when isolated on the surface of the
