448 ORGANIC LESION OF THE PYLORUS IN THE HORSE. 
opposite to our own habitation ; so that we were, luckily, 
most fortunately situated. 
We found the mare lean and hide-bound, with a long 
rough coat, inclined to continual somnolency, with every 
indication of weakness induced by fatigue, privation, and 
disease. A seton, put in the chest by some farrier, for what 
purpose was very doubtful, had produced considerable swell¬ 
ing; and this interfered with the movements of the fore limbs. 
The mucous surfaces were pale and infiltrated; the pulse 
slow, almost to imperceptibility. The chest, auscultated 
and percussed, appeared to us in a state of perfect integrity; 
save that the pulsations of the heart seemed to us occasion¬ 
ally prolonged. The oesophagus, throughout its entire cervi¬ 
cal course, gave evidence of no enlargement or puffiness 
indicative of pouch or dilatation. {Jabot.) 
All these signs of general exhaustion, joined to the fre¬ 
quent vomitings of which we now had proof cle visu , led us 
to suspect cancerous disease of the pylorus ; though this 
was but an induction to which we could attach but feeble 
weight, seeing we were wanting in facts to form our diag¬ 
nosis upon. Being most anxious nevertheless to ascertain 
how far we were correct, we begged of the owner of the 
mare to give us due notice of her death, which we had pre¬ 
dicted would not be far distant. 
We had frequent opportunity, as the mare passed daily to 
her work, of w itnessing the facility with which she relieved 
herself of the alimentary matters that had accumulated in 
her stomach. Her appetite was uncertain; though it 
was always when she had eaten over-night that, in the 
morning afterwards, vomiting came on: and it took place 
in this way. As soon as morning arrived, after having tra¬ 
velled some kilometres, she stopped eating, stretched out her 
head and neck somewhat, the abdominal muscles at the same 
time moderately ( legerement ) contracting, and with no efforts 
beyond this, threw up, through the nose, from three to four 
pints of liquid matters, mixed with a large quantity of ali¬ 
mentary matter, which had already been submitted to the 
action of the gastric juice, as indeed was apparent enough 
from the acetous odour emitted by it. Afterwards she w ould 
continue her work to emit again several times in the course 
of the day. At evening, when she entered her stable, her 
appetite proved all but gone, she taking scarcely anything 
during the following night; though this did not incapacitate 
her from returning to her work the next day. This inappe¬ 
tence continued for a day, or, at most, for two days, during 
which time she ceased vomiting. Then, about the third
