Goat-Pox. 
The goat has a variola of its own, which possesses as special 
and distinctive characters as that of the animals I have already 
described, and is entirely independent of infection from other 
species. In some countries this variola caprina is apparently 
unknown, in others it is extremely rare, while in at least one 
country, Norway, it is a frequent, if not a continuous disorder 
amongst the caprine population. I am not aware if it has ever 
been witnessed in this country, where goats are so few in number. 
For Germany, Hering says the disease is rare.* Hertwigf de¬ 
scribes an outbreak, and gives illustrations of the eruption. The 
animals were at first unwell, and there was diminution of the 
lacteral secretion, with great seusitiveness of the udder—the goats 
had been in milk about three weeks. The first pock was seen on 
the udder, and on the fifth day was the size of a pea, standing 
about two lines above the skin, flat, apex rounded, moderately 
red, with a small areola, which increased in size. Two or three 
days afterwards the pocks were reduced to the size of a hemp- 
seed, pale-red and firmly adherent to the skin. On the tenth day 
they were quite dry and covered by a thick brown crust, which 
on the eighteenth day fell off, leaving a cicatrix. The disease had 
much more resemblance to cow-pox than to sheep-pox. Spinola, 
in 1847, witnessed a similar outbreak, the eruption being most 
visible on the udder. In September, 1832, the disease appeared
