some comparative trials of different methods made before they 
discredit modern science and modern laboratories by publicly 
expressed doubts ? Moreover, the facts do not warrant the state¬ 
ment that the method of diagnosis in general use is lacking in 
conclusiveness to a majority of scientific minds. 
Permit me to relate briefly a typical case of rabies which 
occurred in the District of Columbia. A dog broke the chain 
with which he had been fastened and escaped from its owner’s 
premises in Georgetown about n A. M., April 27, 1900. It ran 
for about two hours, covering six or eight miles. During this 
time it attacked fourteen persons and succeeded in biting two. 
It bit two horses and four dogs and attempted to bite several 
other animals, and was finally killed by a man whose brother it 
was viciously attacking. The post-mortem examination of this 
dog indicated rabies. Inoculated rabbits died of rabies. One 
of the horses which was bitten in the nose was taken to the ex¬ 
periment station of the Bureau of Animal Industry for safe 
keeping. This horse developed rabies June 4, after an incuba¬ 
tion of 38 days. The disease was very intense, the animal 
violently kicking, pawing, and tearing its flesh with its teeth. 
It died June 5. Two sheep were inoculated with an emulsion 
of the medulla of this horse. With one the virus was injected 
at the base of the ear, with the other it was injected into the 
connective tissue behind the right shoulder. The former sheep 
remained well ; the latter showed symptoms of rabies July 1, 
after an incubation of 26 days. The first day of its illness this 
sheep was very vicious, attacking everything that came into its 
stall; if sticks were held towards it, it would strike them with 
its head so violently as to knock them from the hands of a 
strong man ; it also snapped and bit at sticks very much as 
would a vicious dog. The second day it was down 011 its side, 
paralyzed and unable to get up. It died July 2. 
If this disease, which developed in a dog, which was com¬ 
municated by biting to a horse and which was inoculated by 
virus taken from the medulla upon rabbits and a sheep, was not 
rabies, what was it? Will those who express doubts as to the
