the barium ; while the contrary is the case with the manganese and 
the oxygen which peroxidizes it. This may be demonstrated by 
filling a bottle with chlorine and introducing some finely-powdered 
binoxide of barium mixed with a little water. An active efferves- 
cence ensues, and after a time the chlorine will be found to have 
disappeared, its place beg taken by oxygen, which, however, will 
not affect ozone paper. Another difference between the two 
metallic peroxides is also mentioned. Sulphovinic acid when 
heated with binoxide of manganese yields aldehyde; but when 
heated with binoxide of barium it yields oxygen, olefiant gas, ether, 
and sulphurous acid. Binoxide of hydrogen prepared from binoxide 
of barium is decomposed by binoxide of manganese. M. Baudri- 
mont states that he has succeeded in preparing binoxide of hydrogen 
from binoxide of manganese, which is decomposed by binoxide of 
barium. And further, the two oxygenated waters from these 
different sources when brought together mutually destroy each 
other. The author also states that when oxygenated water is sub- 
mitted to the action of the battery, equal volumes of hydrogen and 
oxygen are obtained, showing that the binoxide of hydrogen is 
decomposed in preference to the water. M. Baudrimont speculates 
reasonably enough that all bodies may exist in two allotropic modifi- 
cations. Hydrogen, for example, giving, as we have seen, two 
distinct binoxides, it is probable that it is present in distinct and 
complementary states in those oxides. 
Some new compounds of sulphur and carbon have been obtained 
by O. Loew. Sesquisulphide of carbon is an amorphous brown 
body, which decomposes into its constituents when heated to 
210° C., indicating a loose state of combination of the elements. A 
hydro-sesquisulphide of carbon is also a brown amorphous body, 
having a faint odour of garlic. When this body is boiled with 
alkahes it gives oxalic acid and lower sulphides of carbon. By 
acting on a chlorime compound of hydro-sesquisulphide of carbon 
dissolved in bisulphide of carbon, with a solution of bromine in 
bisulphide, the author obtained a body which appeared to be mono- 
sulphide of carbon, but found it impossible to procure the com- 
pound perfectly pure. 
Among the novelties in organic chemistry, we may first allude 
to the discovery by Drs. Bence Jones and Dupré of a substance 
resembling quinine in all the tissues of the body—resembling 
quinine, that is, in being precipitable by the same reagents, and in 
being possessed of the property of fluorescence. About the 
chemical composition of the substance nothing is as yet known or 
has been made public. The substance is obtained by first treating 
the animal matter with a dilute acid, then neutralizing the acid 
solution with an alkali, and subsequently extracting the fluorescent 
substance with ether. Not having as yet obtained the substance in
