with tuberculosis or intestinal disease. 
For these reasons the ‘“uviol” process, 
which destroys disease germs, but spares 
the acidifying organisms in milk, has been 
developed. ‘The process is based upon the 
power of violet and ultra-violet rays to 
paralyze the growth of vegetable organ- 
isms. The bactericidal efficiency of these 
rays is now universally recognized. By the 
“uviol” process the germs of disease, chiefly 
tubercle bacilli and pus-forming bacteria, 
which the milk of a cow may contain, even 
before the veterinary inspector can detect 
the disease and remove the animal from the 
herd, are killed without altering the nat- 
ural state of the raw milk. 
In the industries dependent on fermenta- 
tion, also, the “uviol” process will soon find 
important applications, as yeast and mold 
fungi are likewise destroyed, though less 
rapidly than bacteria, by ultra-violet rays. 
The success which has been attained in 
purifying water with ozone has naturally 
led to attempts to sterilize milk by means 
of the same agent. The experiments soon 
proved, however, that the conditions in 
the two cases are entirely different. In 
water, the destruction of organic matter is 
desirable, but in milk this must be avoided, 
if the milk is to remain fit for use as food. 
The quantities, both of organic matter and 
of bacteria, which the two liquids contain. 
also differ widely. Even the results ob- 
tained in ozoning water, however, appear 
to indicate that milk cannot be perfectly 
sterilized by direct action of an electric 
current, because the ozone generated by 
the current passes through the liquid in 
large bubbles, making unfit for use those 
portions of the milk which it touches and 
exerting no germicidal action on the rest of 
the milk. In order to sterilize milk com- 
pletely without injuring it, the ozone must 
pass rapidly through it and come into con- 
tact with every particle. 
For this purpose Dr. Emil Wiener has 
made experiments with atomizers produc- 
ing sprays of exceeding fineness, in which 
the diameters of the drops range from 12 
to 20 millionths of an inch. As these drops 
are little larger than bacteria, any bacteria 
which they contain are fully exposed to 
the action of ozone coming into contact 
with the drops, and are instantly killed even 
by greatly diluted ozone. The ozone is 
then quickly removed from the milk by the 
same apparatus by which it is applied. In 
this apparatus the milk is atomized by a 
jet of compressed air, mixed with ozone. 
The milk falls to the bottom of a glass ves- 
sel, from which the ozonized air escapes by 
an orifice above the level of the liquid. Be- 
fore the milk is drawn off it is thoroughly 
aerated by a current of compressed air 
which has been filtered through glass wool, 
calcium chloride and soda lime. In this 
way Dr. Wiener succeeded in freeing milk 
completely from disease germs and toxins 
and improving its “keeping” qualities, with- 
out affecting its taste, odor, or chemical 
composition.—Umschau.
