In Persia according to Bruce goats suffer from a form of variola, having
larger vesicles, umbilicated and approximating to, if not identical with
cowpox. In Algiers there is found a goatpox from which sheep are alleged
to be immune (Nocard, Peuch, Bremond, Galtier) so that further
observations are wanted to put the different forms of variola of the
goat in their proper places. In a country where sheeppox is constantly
present, there is of course the possible source of fallacy of
experimenting with animals that have already had the disease, therefore
it would be expedient to put all forms of goat variola under police
control.
