peared on the second; the pustules themselves preceded the in- 
flammation some days. This man had not been in contact with 
any cow, but on the 11th of February he had shod a horse suffer- 
ing from grease. There existed, at the time, numerous crack 
about the hands. The diszase from which the horse was suffering 
was certified by a qualified veterinarian. Various inoculations 
were practiced with the liquid taken from the pustules presented 
‘y B—, with the effect of reproducing the same disease. The 
most perfect set of experiments were made by M. Maunoury, who 
transmitted the virus through four sets of cases. The following 
are the results of his observations: 
1, That virus obtained from the hands of the farrier B—-, 
and inoculated on the arm of an infant, produced a full pustule, 
having all the character of ° vacvine pustule—form, evolutior, 
termination. 
2. That lymph taken from this pustule, and inoculated on the 
arm of three persons, had produced identical pustules, which are 
truly vaccine. 
3. That the transmission of the virus by successive generationa 
has not diminished the intensity of the force of the poison. One 
of the set of cases presented large pustules, depressed in the centei, 
and filled with matter; each pustule served for several inocu- 
lations and the charging of several sets of glasses. 
4, That from these facts it is evident that the virus taken froza 
the pustules of the farrier was identical with the vaccine.” * 
SuURFEIT. 
The term surfeit is used to designate an eruptive affection cf 
the skin, which usually makes its appearance very suddenly 
There is nothing dangerous about it, and it sometimes disappears, 
in the course of a few hours, without any medical treatment. It 
usually appears in warm weather, and especially among horses 
that are in a state of plethora, from the use of a large quantity 
of meal, or what is known as cut feed.
