periments carefully and cannot get a single “ Butter Crystal ” 
from tallow, lard or oleomargarine or any mixture of them, by 
any means he can devise. He says he has “ carefully followed 
all the details given and can only get a pure tallow crystal,” 
and that other observers report likewise. From the evidence 
already before us it would seem that observers unanimously 
agree that Dr. Taylor’s methods are accurate and reliable; that 
it is possible to tell, by aid of the microscope, the difference 
between butter and other fats; that only one observer disputes 
it; and that his methods completely fail in the hands of other 
observers. 
Tur THERAPEUTICS OF Bacterta.—It would seem, at last, 
that some practical value is to come from our knowledge of 
pathogenic bacteria. It is a well known fact that some species 
of bacteria exert a very destructive influence upon the culture 
of others. Accepting this, an Italian, Dr. Cantani, went to work 
to discover some pathogenic microbe that would exert such an 
unfavorable influence upon the bacillus of tubercle. The ex- 
ceedingly common bacterium termo was found to have such an 
effect. Repeated experiments proved that inhalations of these 
microbes had no injurious effects whatever upon animals. Hence 
he proceeded to make a pure culture of the bacterium termo 
and diluted it largely with beef tea. This diluted culture the 
patient, affected with purulent sputum in which were numerous 
tubercle bacilli, was made to inhale by means of an atomizer. 
Asa result, the tubercle bacilli rapidly diminished in the sputum, 
while the bacterium termo as rapidly increased. The fever de- 
clined, the patient increased in weight and general health. Of 
course, ‘‘ one swallow does not make a spring,” but should the 
researches of Cantani be verified, we have a positive and simple 
cure for tuberculosis. Koch has lately shown that the comma 
bacillus of cholera cannot exist in the presence of septic bacteria. 
What an immense field is opening here for the diligent student. 
Is it possible we are to have positive antidotes to these dreadful 
diseases? Andif to these why not to many others? Itis almost 
too good to believe.
