have been able to train theirs. Mr. L: A. Legros 
also referred to education in his presidential address to 
the Institution of Automobile Engineers on October 11, 
Never, he said, in the history ot engineering has the 
ignorance of science by the politicians, the military, 
and other authorities been so openly displayed as in 
the early stages of the war, and never has it proved so 
costly in time, in life, and in material. How, many 
lives and how many millions of pounds, he asked, 
would the country have been saved if as much study 
in time and thought had been expended on science 
as on classics by our law-makers and Iaw-givers? He 
pleaded that science should be given its proper place 
in education, and that due care should be exercised in 
providing suitable training for those women who, as 
mothers and teachers, would have charge of the 
earliest training of our future men. 
SOCIETIES AND ACADEMIES. 
Paris, 
Academy of Sciences, September 25.—M. Camille Jor- 
dan in the chair.—E, Belot: The origin of the rota- 
tions and revolutions in the forward or backward 
sense, as well as the origin of cometary orbits.—J. 
Guillaume ; Occultations of the Pleiades, observed on 
September 16, 1916, with the 16-cm. Briinner equato- 
rial of Lyons Observatory.—M. Boll and L. Mallet ; 
Determination of the practical constants of the 
Coolidge tube. The Coolidge tube is very stable, and 
the X-radiation can be maintained for a long time 
constant, both as regards emissive power and degree of 
penetration. It is easy to change from hard to soft 
rays and the reverse. The practical yield is of the 
same order as other focus tubes for soft rays. The 
radiation from a Coolidge tube is not appreciably 
more homogeneous than that of other tubes.—J. 
Bougault : The acidylsemicarbazides. A general account 
of their physical and chemical properties as a group. 
—P. Paris: Sphaeromicola topsenti, a new genus and 
species of Ostracod.—A, Lumiére: The comparative 
action of antiseptics on pus and on pure cultures. The 
experiments were carried out with three disinfectants 
of different types—phenol, sodium mercury-phenol- 
disulphonate, and sodium hypochlorite. These were 
allowed to act under similar conditions upon the con- 
centrated pus, culture of the pus, and a pure culture 
of the predominating staphylococcus from the pus, and 
also upon 1 per cent. dilutions of these. The albu- 
minoid substances present in the pus attentuate slightly 
the bactericidal effect of phenol; this action is a ‘Tittle 
more marked with the mercury compound, and _ be- 
comes very important with the hypochlorite.—R. 
Wurtz and E. Huon: The variolisation of heifers 
immunised against the vaccine.—Em. Bourquelot and 
A, Aubry: The biochemical synthesis of a-propyl-d- 
galactoside with the aid of a ferment contained in air- 
dried low veast.
