minable, and may, with very slight variations, he calculated

Secondly. That the phenomena or symptoms included under 
the term inflammatory fever, when divested of all obscurity, 
when traced to their cause, are phenomena resulting from 
accumulation or increment of animal heat, and are differing 
phenomena according to the degree of increment and the 
rate of its progress towards the fatal degree. 
VACCINATION DIRECT FROM THE COW. 
It is a matter of much regret that so little has been done in 
England towards the determination of the value of the practice 
of what is known as ‘^'animal vaccination.^^ We learn from Dr. 
H. Blanc, who has made personal inquiries upon the subject 
on the Continent, that experimenters abroad seem at length to 
have satisfactorily vindicated the superiority of the mode of 
protecting the human subject against smallpox by transmit¬ 
ting to him cow-pox direct from the heifer, and that animal 
vaccination is now’ generally encouraged in Paris, Brussels, 
Naples, Marseilles, and other places, on that account. As 
in this country we are, one and all, dissatisfied with the 
scanty supply of lymph, and its indifferent character, in the 
face of the greater need of a large extension of vaccination 
and revaccination, and a widespread prejudice in the public 
mind as to the possible transmission of serious idisease by 
these operations, we should earnestly ask ourselves whether 
we cannot at once profit by the doings of our Continental 
brethren, and rid ourselves of our present inconvenient posi- 
sition in regard to the general question of vaccination. It 
may be that animal vaccination has not been practised, 
merely from the want of opportunity, and not simply from 
disinclination to adopt it. Dr. Blanc, we believe, is now 
prepared with heifers affected with vaccinia, from whom a 
supply of lymph may be obtained; and he is himself seeking 
to carry out the practice of animal vaccination extensively. 
The advocates of the new practice urge, not only that its 
adoption at once prevents the possible transmission of dia¬ 
thetic diseases and other ailments arising from the use of 
degenerated lymph, but that the prophylactic properties con¬ 
ferred upon man by vaccination are lessened in direct propor¬ 
tion to the more or less complete abstraction of lymph from
