of foreign breeds to cross with the indigenous breed takes 
place. 
In consulting the archives of the Haute-Garronne, we find 
that in the years 1852 to 1857, 1306 sheep were attacked 
with variola, and eighty died, which is about six per cent. 
It is also remarked that in certain years the mortality is 
not more than two per cent., while in others it amounts to 
forty per cent. 
The same difficulty exists in the results furnished respec¬ 
tively in inoculation. JVI. Delafond gives a mortality of 
three per cent on 10,416 sheep, these belonging to flocks 
already invaded by the malady. But he affirms that in the 
severest epizootics, the mortality from inoculation performed 
on healthy sheep, in flocks where the malady already appeared 
was only one per cent. These results are the more sur¬ 
prising, as they are in direct contradiction to what is stated 
by the majority of other observers, who almost all agree that 
variola is fatal in proportion to its intensity and extent, and 
that the virus inoculated in this case, whatever may be the 
source from whence it has been obtained, is always more 
dangerous than when the epizootic is milder. 
On the other hand, there are statistics of a later date 
which upset these of M. Delafond. M. Mariage, veterinary 
surgeon, of Bouchain, has observed a mortality of seventeen 
per cent, among 2984 sheep inoculated in 1846 in the North 
of France; which is higher than that of the malady itself in 
the French breed of sheep, which was only six per cent, in 
the same number attacked. 
It is found that the results obtained by M. Guillaume, 
veterinary surgeon, of Issondon, are greatly in favour of 
inoculation, inasmuch as in the years 1822 and 1824, in 9443 
sheep inoculated, which formed part of twenty-seven flocks, 
in which the malady had broken out, fourteen only died ; 
which was one in 674; while, in the same flocks which 
were attacked by the malady, the mortality amounted to ten 
per cent. 
One advantage from inoculation is, that it shortens the 
duration of the disease. It should, therefore, only be re¬ 
commended when the flocks are already attacked by the 
malady. 
In imitation of vaccination, it has been recommended to 
inoculate lambs some little time after their birth, as a 
hygienic measure. To appreciate the value of this, it is essen¬ 
tial to appeal to statistics. JVI. Lebel quotes an instance in 
which 508 lambs were inoculated, and the loss was twenty. 
In Austria, in 8000 cases not one died. At Brabancais’,
