edge is unfavorable to this hypothesis, and it is regarded as an¬ 
tiquated, discredited and unworthy of serious consideration in 
the absence of direct and convincing evidence. If we admitted 
the spontaneous generation of the disease, however, such a con¬ 
clusion would in no sense benefit the dog nor those interested 
in that animal. On the contrary, it would make us more sus¬ 
picious of the canine species and require all the more rigorous 
destruction of superfluous animals with the strict enforcement 
of regulations to prevent contagion.

TANNOPINE (VETERINARY). 
Manufactured by the Farben-Fabriken of Elberfeld Co. (Germany). 
Tannopine is a chemical combination of tannic acid and 
hexa-methylen-tetramine. The glucoside tannic acid is so 
well known that it requires no further explanation. Hexa- 
methylen-tetramine is the product of a basic compound derived 
from ammonia by the substitution of NH 2 for the H molecule, 
with methylen, a radical molecule of the composition CH 3 . 
Tannopine is a reddish-brown powder, odorless, tasteless, of a 
slightly acid reaction (almost neutral), insoluble in water, alco¬ 
hol, ether and dilute acids, but dissolving gradually in weak 
alkaline fluids. It contains about 87 per cent. ac. tannic and 
like the latter is incompatible with compounds of iron. On ac¬ 
count of its chemical composition it is not dissolved until it 
reaches the duodenum. Beginning at this portion of the gut it 
exerts its action as a non-irritant astringent, antiferment, and 
intestinal antiseptic throughout the entire length of the intes¬ 
tinal canal, and is of great service in the treatment of diarrhoeal 
affections, acute and chronic intestinal catarrh, and enteritis of 
horses, cattle and the smaller animals. 
Dose.—Horse, 3 ss—ii; cattle, 3 i—iv ; dogs, gr. 15-45.
