MISCELLANY. 
duces a white cloudiness in the red solution, and by little and little sepa- 
rates from it yellowish white flocculi. 
Chlurohydric acid when cold has no sensible action, but in proportion 
as it is heated there is produced a white cloud ; by ebullition, the liquid 
bubbles up with noise: a strong smell of petroleum is developed. After 
cooling, the liquid, which was of a milky white, becomes clear, and upon 
its surface floats a yellowish oil which gradually becomes solid. 
Acetic acid dissolves the crystals with facility when cold ; the solution 
is not troubled by water; ebullition has no further effect. 
These crystals are slightly soluble in cold nitric acid : but in proportion 
as they are heated, they are decomposed : there is formed in the acid, a 
milky white cloud, and upon the surface is to be observed drops of a yel- 
low oil; and a well marked odor is then developed, similar to that produced 
by a mixture of the oil of fennel, of anise, and naptha. The elevation 
of temperature gives place to a more vivid reaction ; the acid is colored 
yellow, nitrous gas is disengaged, and a more camphoraceous odor is de- 
veloped. The small quantity of crystals obtained did not permit any 
more experiments. The accordance of the properties described with 
those indicated by M. Buchner, shows clearly that it was stearoptene of 
turpentine, and serves to confirm anterior observations. A. G. V.
