among a drove of goats (54), in Geislingen, attacking first seven, 
then three of the uumber. In some of them there was a fever 
at the commencement, then the eruption of pustules ; though 
generally there was little constitutional disturbance, and only 
dimunition of milk, with soreness of the mammae before the pocks 
appeared. Sheep in contact with these goats were not affected.* 
But Bollinger says it is so infrequent, that in the course of twenty 
or thirty years scarcely half a dozen cases are recorded. He is 
of opinion.that goats receive the disease either from cattle affected 
with vaccina, or sheep suffering from sheep-pox. But he admits 
that though now and again the same form of variola is witnessed 
in cows and goats, yet that the latter, as a rule, remained exempt 
from the disease when confined in the same stable with infected 
cows, and that the inoculation of goats generally yielded negative 
results. In order to prove that goats may be infected with sheep- 
pox, he gives the following on the authority of Prietzsch : “ In a 
stable in which sheep suffering from sheep-pox were confined, 
three goats were simultaneously attacked with the disease, the 
eruption being the same as in the sheep. Upon the udder were 
numerous pisiform variolie, in the form of hard, flattened papules, 
with a trifling amount of lymph; papules were also distributed 
over the body, being more numerous upon the hind extremities 
than the abdomen. Marked symptoms of fever were also pres¬ 
ent, with inappetence, swollen lips, and a somewhat profuse muco¬ 
purulent discharge from the nostrils. In fourteen days convales¬ 
cence was established. Two other goats were inoculated on the 
ear with the virus of sheep-pox; a single pustule formed at the 
seat of inoculation, and the animals did not afterwards take sheep- 
pox.” 
That there is no relationship, so far as origin is concerned, be¬ 
tween sheep-pox and goat-pox, nor yet, for that matter, human 
variola, is evident if we look at a count rywhere the latter is all but 
unknown, and the former is not seen. From 1864 to 1876 in¬ 
clusive, sheep-pox has been reported only twice in Norway; in 
1865 there were two cases, and in 1868 fifteen cases, all due to 
Op. cit., 1856.
