JOHN PHILLIPS, a Tradesman of this town, had the Cow Pox at so early
a period as nine years of age. At the age of sixty-two I inoculated
him, and was very careful in selecting matter in its most active
state. It was taken from the arm of a boy just before the
commencement of the eruptive fever, and instantly inserted. It very
speedily produced a sting-like feel in the part. An efflorescence
appeared, which on the fourth day was rather extensive, and some
degree of pain and stiffness were felt about the shoulder; but on the
fifth day these symptoms began to disappear, and in a day or two
after went entirely off, without producing any effect on the system.

_CASE IV._

MARY BARGE, of Woodford, in this parish, was inoculated with
variolous matter in the year 1791. An efflorescence of a palish red
colour soon appeared about the parts where the matter was inserted,
and spread itself rather extensively, but died away in a few days
without producing any variolous symptoms[1]. She has since been
repeatedly employed as a nurse to Small-pox patients, without
experiencing any ill consequences. This woman had the Cow Pox when
she lived in the service of a Farmer in this parish thirty-one years
before.

[Footnote 1: It is remarkable that variolous matter, when the system
is disposed to reject it, should excite inflammation on the part to
which it is applied more speedily than when it produces the Small
Pox. Indeed it becomes almost a criterion by which we can determine
whether the infection will be received or not. It seems as if a
change, which endures through life, had been produced in the action,
or disposition to action, in the vessels of the skin; and it is
remarkable too, that whether this change has been effected by the
Small Pox, or the Cow Pox, that the disposition to sudden cuticular
inflammation is the same on the application of variolous matter.]

_CASE V._

MRS. H----, a respectable Gentlewoman of this town, had the Cow Pox
when very young. She received the infection in rather an uncommon
manner: it was given by means of her handling some of the same
utensils[1] which were in use among the servants of the family, who
had the disease from milking infected cows. Her hands had many of the
Cow-pox sores upon them, and they were communicated to her nose,
which became inflamed and very much swoln. Soon after this event Mrs.
H---- was exposed to the contagion of the Small Pox, where it was
scarcely
