sense that it fortifies the animal for the future against at- 
tacks of the disease. May be in 54*34 subjects, on whom 
the effects of cohabitation have proved next to nothing or 
very light, 45*65 subjects contracted the disease to a degree 
more or less intense, of which 35*93 became cured, and 8*69 
succumbed to the effects of the disease. While, on the other 
part, it results from experiments on inoculation made by the 
committee : — out of the same number, 100 animals, submitted 
to the proof of this operation, 6 1*1 1 have experienced nothing 
but very benignant effects from it ; that it is more or less 
dangerous or altogether hurtful in its consequences for 38*88 
subjects ; that of these 38*88 subjects, 27‘77 have become 
cured, after having suffered gangrenous affections more or 
less grave in character, and 1 1*1 1 have sunk from gangrenous 
superventions. 
The following table presents to the eye the calculated re- 
sults afforded by the tw r o sets of experiments on inoculation 
and cohabitation instituted by the committee. 
COHABITATION. 
Number of subjects of ex- 
periment being supposed 
to be . . . 109 
Cohabitation will be nil in its 
effect, or very benignant 
for .... 54*34 
And more or less hurtful for 45*65 
In this last account, the re- 
covery will be represented 
by 36*95 
And the deaths by . . 8*69 
As a definite result, the num- 
ber of animals, departing 
from the tests of cohabi- 
tation with their health 
saved or recovered, will 
amount to from this calcu- 
lation, on an average . 91*29 
And those of the dead at . 8*69 
INOCULATION. 
Number of subjects of ex- 
periment being supposed 
to be . . • 109 
The inoculation would be 
beneficial for . . .61*11 
And more or less hurtful for 38*88 
In this last calculation, the 
recoveries will be repre- 
sented by 27*77 
And the deaths by . . 1141 
As a definite result, the num- 
ber of animals departed 
from the tests of inocula- 
tion with their health saved 
or recovered, will amount, 
after this calculation, on 
on average, to . . . 88*88 
And that of the deaths to . 11*11 
The first fact which strikes us in this table is, that inocu- 
lation has occasioned a greater mortality than the disease it 
was designed to prevent. Besides, we must take it into 
consideration that animals who have borne up against the 
gangrenous results of inoculation have still lost a great deal 
of the value they would fetch after their cure, in conse- 
quence of their not having recovered their health for a long 
while after being much reduced in condition, and remaining
