DENSITY OE OZONE. 
Dr. Andrews and Mr. Tait have made some experiments 
which lead them to the conclusion that, provided ozone is 
an allotropic modification of oxygen, its density is four times 
as great as that of oxygen. As ozone cannot be obtained 
pure, but only mixed with a very large proportion of ordinary 
oxygen, the density could only be determined by heating 
the ozonized oxygen to 448° Fahr. and upwards, and then 
observing the alteration of volume. 
By this means it w r as found that there was always an aug- 
mentation in the volume of the gas, and this was accurately 
measured. The amount of ozone in the gas operated upon 
w r as one three hundred and fiftieth its weight, when the gas 
was obtained by the electrolysis of a mixture of water with 
one eighth sulphuric acid ; and w T as about double as much 
w hen a mixture of equal parts sulphuric acid and water was 
submitted to electrolysis . — . Pharmaceutical Journal . 
INHALATION OE CHLOROEORM IN TETANUS. 
Practitioners of human medicine having successfully 
treated several cases of tetanus by causing the patient to 
inhale the vapour of chloroform, it is not too much, perhaps, 
to anticipate the like results in the lower animals. The 
practice appears to be to keep the system under its influence 
for some time, but not to produce complete insensitiveness. 
REMEDY EOR CONSUMPTION. 
The Tartars in the eastern provinces of European Russia 
use for many purposes a particular beverage called Keimyss, 
which is prepared from mare’s milk. One of the qualities of 
this beverage is that it cures diseases of the lungs, if used in 
a certain way. The Russian medical men have lately learned 
the w : ay from the Tartars, and the effect of several trials is 
said to be all that could be desired; so that hospitals are 
being established for the purpose of rendering this discovery 
as beneficial as possible.
