Murat: The preparation by catalysis of decahydro- 
quinoline and of decahydroquinaldine. Ten atoms of 
hydrogen can be added to the quinoline and quinaldine 
molecules by nickel catalysis, provided that the tem- 
perature of the reaction is suitably chosen and that a 
very active nickel is employed. The decahydro- 
quinaldine is new, and its properties and those of 
some of its derivatives are given._Georges Charpy :

ing on the solution of copper in nitric acid. Solutions 
of nitric acid of strengths readily attacking copper 
(30 to 48 per cent.) when at rest, lose their power of 
dissolving the metal when rapidly rotated or shaken. 
As an example, a solution of 36 per cent. nitric acid 
which dissolved 0-397 gram of copper from a given 
piece of metal at rest in fifteen minutes, dissolved 
only 0:004 gram in the same time when the metal was 
rotated at 386 turns per minute.—L. Crussard: Limits

the haemoglobin of the blood corpuscles put in contact 
with mixtures of carbon monoxide and oxygen com- 
bines with the two gases in proportions defined by 
their respective partial pressures and governed by the 
law of mass action. These experiments have now 
been extended to living animals (dogs), and the same 
laws are found to be applicable.

It is shown that - 
with a given mixture of carbon monoxide and air 
when breathed by an animal, the carbon monoxide 
is fixed by the blood up to a certain limit which cannot 
be passed. Oxygen displaces the carbon monoxide 
from the blood,.and pure oxygen constitutes the best 
treatment for carbon monoxide poisoning.—André 
Mayer and Georges Schaefier : The proportion of lipoids
