comes deep brown, changing in a few minutes to brownish black; or if 
chlorine water be added to another portion, it changes from yellow to a 
bright green. The distillation need not be long continued as the kinone 
is very volatile-—Proceed. Chem. Soc., part 10, p. 226. 
11. On the decomposition of Salts of Ammonia at the ordinary tempera- 
ture; by H. Bence Jones, M. D.—Dr. Jones shows that evaporation, 
even at the ordinary temperature, of salts of ammonia, causes their de- 
composition by the escape of the ammonia. A solution of the sulphate 
of ammonia, at first neutral to the test liquids, after a while changed lit- 
mus to pink; other salts produce the same result. A solution of the urate 
after standing for a while, presented minute tufts of crystals of uric acid 
along the edge of the liquid Proceed. Chem. Soc., part 10, p. 244. 
12. Styrole.—The oil of storax was named styrole, by E. Simon, who 
obtained it from the liquid storax of the shops by distillation with water. 
Its properties have been investigated by J. Blyth and Dr. A. W. Hoffman 
at Berlin. It is colorless, with a burning taste, and aromatic odor, re- 
sembling a mixture of benzole and naphthaline. It evaporates at all 
temperatures, and boils at 1453°C. A wick dipped in it burns with a 
brilliant smoky flame. This substance consists, according to their analy- 
ses, of 2 equivalents of carbon and 1 of hydrogen, and has analogies with 
benzole and cinnamole.—F'rom the Proceed. Chem. Soc., paré 13, 1845,

13. Salicine; by M. Prrta.—Salicine is a natural combination of 
grape-sugar and of saligenine; the saligenine again is a substance which 
is very readily altered by chemical reagents. Weak acids convert it into 
saliretine, concentrated sulphuric acid into rutiline, nitric acid into carba- 
zotic acid, oxidizing agents into hydruret of salicyle, potash in a state of 
fusion into salicylic acid. 
When salicine is submitted to the action of any agent whatever, two 
cases may occur:—l. If the agent is sufficiently energetic to decompose 
at the same time the saligenine and the sugar, altered products of these 
two substances are obtained, asif the experiment were made on a mixture 
of saligenine and grape-sugar. 2. If, on the contrary, a weak agent is 
employed, the saligenine only is decomposed and the sugar remains unal- 
tered, but it combines with the modified saligenine. Thus chlorine first 
converts it into chlorosalicine ; then into bichlorosalicine ; lastly, into per- 
chlorosalicine: these are combinations of sugar with the saligenine, in 
which chlorine has replaced 1, 2, 3 equivalents of hydrogen. 
Dilute nitric acid changes salicine into helicine. This results from the 
combination of the sugar of the salicine with the hydruret of salicyle 
derived from the oxidation of the saligenine. When helicine is submitted
