its teeth, yaws, arches its back, draws its legs together under its 
body, and manifests tenderness of the loins. A fever shiver 
ushers in the next stage. The animal becomes hide-bound, its 
c.'at stares, there is still greater tenderness of the lumbar region. 
The gait is stiff, joints rigid, ears and horns alternately hot and 
cold; pulse frequent, hard and full; breathing labored, and se¬ 
cretions generally scanty. Rumination is suspended ; deglutition 
performed with difficulty, thirst intense, and mouth hot and 
clammy. There is a watery discharge from eyes and nose. The 
eyes are blood-shot, eyelids swollen, and soon encrusted with the 
dried inspissated secretions from them. Saliva drops from the 
mouth. If blood is drawn, it coagulates with difficulty. The 
dry excrement and high colored urine are scanty and discharged 
with some difficulty. The abdomen is tense and tender. In cows 
the secretion of milk is stopped. In some cases general emphy¬ 
sematous swellings form at this period, and there are exacerba¬ 
tions of all the symptoms towards night-time. This stage lasts 
about three days. 
“ The symptoms increase in severity. Diarrhoea supervenes, 
great weakness appears. The pulse is 90 to 100, weak and indis 
tinct at the jaw. The discharge from the nose and salivation in¬ 
crease. The cough is softer, and on the buccal and schniederian 
membranes, as well as in the clefts of the feet, a vesicular erup¬ 
tion is seen. Ulcers result wherever the vesicles burst. 
t£ An unfavorable termination may be looked for when the 
body becomes cold, breathing quick, exhalations foetid, faeces 
(fluid or bloody) discharged involuntarily, abortion in cows, and 
symptoms of sensibility or consciousness lost. The animal dies 
from the third to the tenth day of the development of the disease. 
‘‘ In favorable cases there is an early dimunition in the sever¬ 
ity of the symptoms ; the diarrhoea is not severe, and there is a 
pustular eruption over the body, or a desquamation of cuticle. 
The convalesence is long, and may last several weeks. 
“ Post mortem appearances .—In the first, or catarrhal stage, 
the lesions are not characteristic of the disease, but, taken in con¬ 
nection with the history of the outbreak, may assist materially in 
diagnosis. The mucous membrane of the fourth stomach, es-
