The duration of the immunity has not been accurately deter¬ 
mined, bnt it appears to be sufficient to carry the animals through 
the season. 
The serum has been used entirely in herds in which the 
disease had already appeared. In some cases only a few ani¬ 
mals in large herds had shown the disease, while in other cases 
a considerable proportion of the herd was dead before the remedy 
was applied. As would naturally be expected under such cir¬ 
cumstances the results of the treatment vary considerably in dif¬ 
ferent herds. In some large herds 95 to 99 per cent, have been 
saved, while in others not more than 40 to 50 per cent, were 
saved. Altogether about 2000 hogs in diseased herds have 
been treated, and of these about 80 per cent, lived. 
In neighboring herds similarly affected and which could not 
be treated on account of an insufficient supply of serum, about 
85 per cent, of the animals in the diseased herds died. This 
indicates that the difference between a death rate of 20 per cent, 
in the treated herds and of 85 per cent, in the herds not treated 
represents the saving to be attributed to the serum treatment. 
The hogs which recover under this treatment thrive and fatten 
well. A form of treatment which is easily and cheaply applied 
and which gives such results as' this can only be regarded as a 
great success and as solving, from the point of view of the sci¬ 
entific investigator, the question of what to do with hog cholera. 
There are still important questions as to the practical applica¬ 
tion of the treatment which will be considered in a subsequent 
communication.

Notwithstanding the great many advantages that are offered 
by the use of the operating table in securing horses for opera-- 
tions, its cost, the necessity of ample space to establish it, will 
always be an objection to its admission into general practice, 
and on that account will always remain more or less practicable 
for large institutions, extensive establishments or horse-shoeing 
places of importance. To the ordinary practitioner, to the 
country veterinarian, hobbles, old fashioned or of improved 
style, are likely to be more commonly resorted to and for that 
reason those that are presenting the least chances for accidents 
and injuries are deserving of special attention. 
Our attention was called lately to a Danish apparatus modi¬
