SMALL-POX IN SHEEP. 
tuting a total of 10,568 sheep, 1183 sheep (rather more than a 
tenth of the whole number) already had got the disease, of which 
number 638, or more than the half, died. Nevertheless, M. Guil- 
laume inoculated 9443 sheep that were exposed to the contagion ; 
and out of this number but 14 died — about l in 674. 
To these we will add examples taken from foreigners. In Prussia, 
in the case, too, of epizootic sheep-pox, out of 66,716 sheep inocu- 
lated, 1674 have died, 65,042 recovered ; bringing the loss to 24 per 
cent. 
In Austria, in 1810, inoculation was practised upon 8000 lambs 
and 2000 sheep, without any loss whatever. 
These researches appear to afford positive demonstration that ino- 
culation (clavelisation), introduced into flocks already infected with 
the disease, in its first or second stage (bouffte), in situations 
even where the disease prevails epizootically, is an operation which, 
GENERALLY, is attended with no other than the happiest results. 
And that if, in any case, inoculation has, in sheep already con- 
taminated, and under the influence of the fever of incubation, given 
rise to a malignant and fatal pox, such cases ought to be regarded 
as rare exceptions. 
In respect to the inoculations of flocks in good health, but threat- 
ened with inevitable contagion from some vicinity, the loss is very 
small indeed. 
From 1815 to 1819 were inoculated 16,000 sheep, of which 
10,000 were lambs, belonging to the fine flocks of the Marquis of 
Braban^ais ; and the loss, at the most, did not exceed 1 percent. 
Farmer Dupreuil had his flocks inoculated, in consequence of 
their being threatened with small- pox contagion. 1700 ewes, 
three months gone in lamb, were inoculated ; 21 died after taking 
cold. The loss here is but 1 per cent, under such very unfortunate 
circumstances. 
The same year, rather later, the same farmer had 480 sucking 
lambs, and 550 lambs from six to seven months old, inoculated, 
making together a total of 1030 ; and the loss amounted to no more 
than 1 in 500, or thereabouts. 
In general, in prophylactic inoculations, or in such as have been 
instituted at the moment of danger of contagion, we may reckon 
that, whatever be the situation, the season, the breed, the age, the 
condition of the female — in lamb or giving suck — the loss will not, 
under the most unfavourable circumstances, exceed 1 out of 200 
inoculated. Now that experience has shewn the expediency of 
separating the inoculated sheep from those that have caught the 
disease naturally, in order to avoid double inoculation, a natural as 
well as an artificial ; of airing, ventilating, in a word, ptfrifying the 
habitations of the inoculated ; of making use of no other virus save
