MOVING PICTURE CAMERA, AS A 
HAND-CAMERA, BY USING A 
GYROSCOPE 
T a recent meeting of the Société de 
Physique, of Paris, an interesting 
method of taking moving picture 
views was presented by M. De Proszynski. 
Heretofore such a camera had to be 
mounted on a tripod to keep it quite steady, 
and it was generally turned by a hand-crank. 
The inventor succeeds in making a hand- 
camera for use in taking such views. He 
keeps it steady by using the principle of the 
gyroscope in an ingenious way, so that 
holding it in the hand causes no trembling. 
But the problem was how to drive the gyro- 
scope and also the film machine, as an elec- 
tric motor with a battery is not practical, 
neither is a spring motor. He uses a small 
compressed air motor devised for the pur- 
pose, and it is very compact. It gives no 
shocks when running, which is, of course, 
an essential point. A unique feature is that 
an ordinary bicycle pump is used to fill the 
air cylinder of the motor, so that the whole 
can be made in the form of a hand-camera 
about the size of a large kodak, and it is 
thus self-contained. The inventor showed 
what the camera would do by projecting 
some street views on a screen. These were 
taken when moving the camera about in the 
hand very rapidly, and the images were 
remarkably sharp. 
MEDICINAL PLANTS 
HE researches presented by Prof. 
Bourquelot to the Paris Academy of 
Medicine appear to show that the 
medicinal qualities of plants are greatly 
modified by drying them for use, and this 
action is much greater than may be sup- 
posed. The chemical as well as therapeutic 
qualities are found to be changed by the dry- 
ing. Considerable experimental work was 
done in order to bring out these facts, and 
it is shown that when the plant is dried there 
is an interaction of the various bodies it 
contains so that some of these destroy oth- 
ers, and in this way many of the active prin- 
ciples of the plants are destroyed or made 
insoluble. However, it is of interest to 
note that this action can be avoided, or at 
least in part. By rapidly sterilizing the 
plants, by dipping them in strong alcohol at 
the boiling point, the author was able to pre- 
vent any further destruction of the soluble 
ferments. Owing to this method, he could 
separate out the chemical principles which 
existed in the living plant, and thus have a 
great advance in analysis of vegetable sub- 
stances, which is always a difficult matter. 
He also prepared new pharmaceutical sub- 
stances which will be likely to give very 
good results for medicinal purposes. It will 
be seen that these results are far- reaching 
and may be very valuable in the interests 
of future researches. 
FORAGE CROPS TESTED 
ANY new forage crops from all parts 
of the world are being tested every 
year. Only a few of these possess 
sufficient value to compete with the crops 
now grown. Four such plants, however, re- 
cently introduced, have given such admir- 
able results that there can be little question 
that they will prove of great value. Ex- 
perience of the last three years has shown 
that Rhodes grass is especially adapted to 
the Gulf coast region. In southern Florida 
three cuttings have been made during the 
winter months and as many as six during 
the entire season. This grass has fine up- 
right stems and good seed habits, and should 
be extensively cultivated in this region,
