careful treatment having been adopted, the results were not so 
serious. The milch goats were the worst attacked, and the mor¬ 
tality was greatest in the largest herds. The total number of 
cases for this year was 129. In the four succeeding years Hansen 
did not know of any outbreaks. 
In July, 1874, goat-pox broke out in two different districts, 
one and a half Norway miles apart, three farms being visited by 
it—one with 150 goats, another with 120, and the third with 60. 
All of these were more or less affected. The disease first com 
menced with slight fever; then followed efflorescence, subse¬ 
quently the eruption on the udder and teats of small vesicles the 
size of a pea, and which soon became converted into pustules. 
Not unfrequently suppurating furunculi formed, and the whole 
udder was involved. 
In some instances pocks appeared on the lips. Towards the end 
of August, there were reported 580 cases of goat-pox in the two 
localities. On the neighboring goat-farms the disease was not 
seen. There was no evidence that it could be communicated to 
mankind, though it appeared not improbable that mankind could 
convey it from one flock of goats to another. Ten deaths only 
were reported. In 1875 there were 200 cases. Hansen states 
that altogether there were 1,300 goats attacked, with from twenty- 
five to thirty deaths—about two per cent. The incubative period 
appeared to be short, certainly not longer than a week, while the 
duration of the disease was from two to three weeks in severer 
cases. The pock cicatrices were more or less stellate-shaped. 
Immunity was very rare indeed, nearly every goat exposed to the 
infection taking the disease. The outbreaks always occurred 
during the summer months, and the epizooty did not extend beyond 
Hansen’s official district. Boeck and others competent to judge 
had no doubt whatever that the disease was variola. Neither 
sheep nor cattle, notwithstanding their constant exposure to in¬ 
fection and being crowded with the goats in close sheds, became 
infected. Human variola was not present in the district during 
the years when goat-pox prevailed.

because they support in the strongest manner the position I have
