THE MIcROSCOPE. ook 
Haushalter have been experimenting with flies to show they 
may be the carriers of the Bacillus of Tuberculosis.* They 
captured some flies from the vessels containing the expector- 
ations of patients suffering from Tuberculosis. These flies soon 
died, and examination showed the presence of abundant Bacilli 
of ‘Tuberculosis both in their excrement and in their abdominal 
cavities. Since the flies die and crumble to dust in odd corners, 
the Bacilli may readily be liberated, and the germs may also be 
landed along with the excrement on articles of food and cloth- 
ing. While it is not yet known how the life within the fly may 
affect the vitality of the Bacilli, it seems at least advisable that 
the precaution should be taken of covering and of sterilizing the 
expectorations of Tuberculosis. 
The Med. Times quotes from the address of Dr Sternberg, 
which was delivered at the College of Physicians, a large number 
of degrees of heat at which certain pathogenic organisms die. 
This address of Dr Sternberg’s reflects great credit on its author, 
being the first of its kind in this country, and carried to such a 
great extent. Among the various organisms and degrees of heat 
required to kill them we note some of the more important:

At the late German Medical Congress at Wiesbaden, Dr Hanau, 
of Zurich, showed microscopic and macroscopic specimens illus- 
trating his success in inoculating cancer from one rat to another.
