rent cause upon the upper part of the thigh of a sucking
colt, the property of Mr. Millet, a farmer at Rockhampton, a village
near Berkeley. The inflammation continued several weeks, and at
length terminated in the formation of three or four small abscesses.
The inflamed parts were fomented, and dressings were applied by some
of the same persons who were employed in milking the cows. The number
of cows milked was twenty-four, and the whole of them had the
Cow-pox. The milkers, consisting of the farmer's wife, a man and a
maid servant, were infected by the cows. The man servant had
previously gone through the Small-pox, and felt but little of the
Cow-pox. The servant maid had some years before been infected with
the Cow-pox, and she also felt it now in a slight degree: But the
farmer's wife who never had gone through either of these diseases,
felt its effects very severely.

That the disease produced upon the cows by the colt and from thence
conveyed to those who milked them was the _true_ and not the
_spurious_ Cow-pox[5], there can be scarcely any room for suspicion;
yet it would have been more completely satisfactory, had the effects
of variolous matter been ascertained on the farmer's wife, but there
was a peculiarity in her situation which prevented my making the
experiment.

Thus far have I proceeded in an inquiry, founded, as it must appear,
on the basis of experiment; in which, however, conjecture has been
occasionally admitted in order to present to persons well situated
for such discussions, objects for a more minute investigation. In the
mean time I shall myself continue to prosecute this inquiry,
encouraged by the hope of its becoming essentially beneficial to
mankind.

heels of horses. This I have often inserted into scratches made with
a lancet, on the sound nipples of cows, and have seen no other
effects from it than simple inflammation.]

prevalence of this distemper was resident at Gloucester, and
Physician to the Hospital there, (where it was seen soon after its
first appearance in this country) had opportunities of making
numerous observations upon it, which it is his intention to
communicate to the Public.]
