of total seizure to prove the virulence of the blood in the first 
instance, and the mass of muscles secondarily. 
At the Fifth International-Veterinary Congress, held in 
Paris in 1889, M. Butel, who may be said to have initiated the 
crusade in favor of total seizure, submitted a table showing 
the results of the experiments published at that date regard¬ 
ing the virulence of the blood in tuberculosis. The experi- 
ments quoted were as follows:

At the Congress for Tuberculosis (Paris, 1888) Nocard 
described an experiment which ought to have been included 
in the above list. He injected 1 cm. of a virulent culture of 
tubercle bacilli into the auricular vein of a rabbit, and four 
hours later he withdrew from the animal’s jugular 1 cm. of 
blood and injected it into the jugular of another rabbit. The 
latter when killed three months after inoculation was found 
to be free from tuberculosis. 
Since the above date Professor Bang, of Copenhagen, has 
published the largest series of experiments of this kind yet 
placed on record. He inoculated defibrinated blood from 20 
tuberculous cows into 38 rabbits and 2 guinea-pigs, the 
quantity of blood injected being in no case less than 5 cc., 
and in most cases from 10 to 18 cc. The inoculations with 
the blood of 18 of these cows yielded negative results. In 
one of the cases that yielded positive results the cow was the 
subject of acute miliary tuberculosis; in the other positive 
case only one of the rabbits had insignificant tuberculous 
lesions, and the other similarly inoculated escaped. 
If to the experiments given above in M. Butel’s table we 
add those by Professors Bang and Nocard, and the 5 by my-
