with Clare Island Survey. This report contained 
tables giving the annual and monthly means and 
extremes of barometric pressure, temperature, and 
rainfall for the district, together with summaries deal- 
ing with humidity and sunshine. An_ exhaustive 
analysis of the wind records kept at Clare Island 
Lighthouse was made, with some interesting results.

Academy of Sciences, January 19.—M. P. Appell in 
the chair—H. Deslandres and L, d’Azambuja: The 
exact study of the second group of nitrogen bands in 
the magnetic field. Recognition of the nature of the 
displacements. The experiments were carried out in 
a magnetic field of 35,000 Gauss. The deviations, for 
A about 4oo, corresponded to a maximum of 1-40 mm. 
for one Angstrém. Four diagrams are given showing 
the changes observed in different portions of the band

cast is taken of the original phonogram, and this is 
enlarged by- hydration and reduced by drying, with 
fixation in each case by aqueous solutions of formalde- 
hyde.—M. de Broglie: The spectroscopy of the Ront-

and uranyl salts. A mixture of uranyl- salts with 
oxalié acid absorbs the ultra-violet rays much more 
strongly than the sum of the ‘constituents. ‘ Details 
of the quantitative study of the absorption are given.

dehydration of glycerol.. An organism has been ex- 
tracted from Dijon water identical in its morphological 
and biochemical characters with Bacillus amaracrylus 
from bitter wines. It can form acrolein from glycerol 
in aqueous solution.—Auguste Lumiére and Jean

an insoluble sulphate. The therapeutic and antiseptic 
properties of this and the analogous chlorine and 
iodine compounds have been  studied.—Gabriel

boric acid in food substances, normal or added. 
Utilising the colorimetric method of estimation de- 
scribed in an earlier communication, figures are given 
for the amounts of boric acid present in a large 
number of animal and vegetable foods.—H. Heérissey
