on Oil of Turpentine and Camphor. 53 
or sodium, as is the case with the alcohols.* The true chem- 
ical structure of camphor must be determined by a further 
study of its derivatives. 
While a dilute solution of hypochlorous acid acts readily 
and rapidly on oil of turpentine, its action on camphor is ex- 
ceedingly slow. In the first experiment I allowed camphor to 
remain in a weak folhtion of hyponitrous acid for eight days, 
and thereupon one day in a concentrated solution. The pro- 
duct of the reaction, a white, indistinctly crystallized solid, was 
washed with water till no acid reaction remained, dissolved in 
alcohol and again precipitated by diluting with water, Itstill

The formation of this substance can be explained by the 
following eames ation:

The result i is a different and a much simpler one where cam- 
phor is immediately brought in contact with concentrated hy- 
pochlorous acid; it is at once transformed into a thick fluid, 
becomes warm, and after some time again hardens to a crystal- 
line solid. This body is the chief product of the reaction, 
though a very small quantity of another organic substance is 
found in the solution, The crystalline substance is dissolved 
in alcohol, precipitated with water and thoroughly washed with 
cold water. It is then again repeatedly dissolved in alcohol 
and crystallized therefrom until obtained quite pure. On its 
analysis I obtained the following results: 
0°2320 ave 0°5940 carbonic acid oy 0°1710 water.
