I These conclusions are : 
1. Immunity in the result of the exposure of the bioplasm of 
lie animal body to the chemical products of the growth of the 
pecific microbes which constitute the virus of contagious fevers 
! 2. These particular chemical products are produced by the 
Towth of the microbes in suitable culture liquids in the labora¬ 
tory, as well as in the liquids and tissues of the body. 
3. Immunity may be produced by introducing into the animal 
ody such chemical products that have been produced in the 
iboratory. 
TREATMENT OF SPRINGHALT BY SHOEING. 
By Me. Montagnao. 
First Case. A bay gelding, three years after his purchase? 
’lowed symptoms of springhalt, and about a year subsequently 
'as brought to Mr. M. While at rest there was nothing in the 
ppearance of his hind legs to attract attention, except a slight 
intraction of the feet at the quarters and the heels. This condi- 
on was about the same in both feet. The exploration of the 
let produced no manifestation of unusual sensibility. The lat- 
ral cartilages, external as well as internal, were pressed on their 
Liperior border against the posterior face of the second phalanx, 
tod seemed to have lost their suppleness and elasticity. When 
j,i motion, the animal exhibited the characteristic spasmodic 
lovements of springhalt in an extreme degree, whether walking 
p trotting, and whether travelling in a straight line or in a 
! ircle. 
L Treatment .—The shoes having been removed, the feet were 
j.loroughly pared, and kept for eight days in a poultice of clay, 
.e was then shod with the “ Watrin ”* shoes, with directions to 
qak the feet for two hours daily and give him walking exercise, 
enewed shoeing, as required, showed an improvement to such 
i extent, that after some six months of the treatment, the 
>ringhalt has almost entirely disappeared. 
* The Watrin shoe has two little caulks on the inside of each branch of the 
oe, close to the heels, upon which they rest, and which they spread.
