The fungoid theory of disease. 
In the artiele whieh appeared in the Oetoher number of 
the Veterinarian on the subjeet of aetive moleeules in vae- 
eine and variolous matter, allusion was made to the researehes 
of Professors Hallier and Du Barry, who are asserted to have 
diseovered fungi in the intestines of persons dead of eholera; 
and also in the morbid produets of other diseases. It is not 
to be presumed that any definite eonelusions ean be drawn 
from the evidenee at present available, but the apparent ten- 
deney of the inquiry is to assoeiate various diseases with the 
development of vegetable organisms in the blood and other 
fluids of the animal body. Whether future investigation 
shall confirm or negative this view of the relation of fungi to 
morbid changes in the organism of the animal, it is very 
desirable that the members of the veterinary profession 
should not be unconcerned spectators of experiments which 
have such an important bearing upon pathology. Hence, in 
the article referred to, it was proposed to record the results of 
microscopic observations upon various animal fluids at inter¬ 
vals. A comparison of the evidence obtained with that 
which may hereafter be collected by investigators will at 
least be interesting, and, possibly, not uninstructive.
