In Fosdinovo I operated with the same ichor on a number of children, and also on a cow near Aulla; many of the cases I left under the care of M. Magnani, surgeon, of the latter place, who favoured me with the following details :-—‘ On the 8th and 11th ult., December 1806, I visited the four boys that you had inoculated with ovine virus, and found that two of them were affected; one had two fine pustules [?] on each arm, the other only one on the right arm. The pustules [?] were similar to those of vaccine, and sur- rounded with a red zone; but a minute examination shewed that their contents were on the eighth day more yellow than in that disease, a condition which they retained up to the period of the formation of the crusts. At my first visit I obtained some ichor from the pustules [?], which was serous but not limpid. 1 inoculated two children with this, and on the seventh day the pustules [?] were filled with a limpid fluid. From these, three other individuals were inoculated, and on the eighth day the contents of the pustules [?] were both limpid and crystalline, as in the true vaccine.
