That on the one side, oil of turpentine sustains the intimate 
relation to the aromatic series here assumed, has been by ex- 
periment abundantly illustrated. I need ‘only to refer to 
th ; ‘ 
turpentine and the formation of cymol from cam 
relations, however, to the fatty series of the bodies under con- 
sideration have not been thus satisfactorily demonstrated. 
Now oil of turpentine occupies apparently a similar position 
with reference to te c acid as acetylene does to acetic acid, 
as is herewith shown

It appeared to me, therefore, to be a subject worthy of in- 
vestigation to ascertain whether the relations ge expressed 
could be proven by experimental research. I e for this 
purpose, made use of hydrated hypochlorous acid as a reagent, 
dnd have been able to obtain a ee ent toe may be regarded

If oil of turpentine (boiling point 159° ¥ is added to a dilute 
aqueous solution of hj pocklarsad acid and shaken, it at once 
becomes — thick and heavy, and soon settles to the bottom 
of the vessel. Were concentrated acid employed, the mixture 
would apuily become heated and other products be formed than 
that sought, or, under the most favorable circumstances, but 
very little of the new body would be obtained. The oil should 
be slowly added, not allowing an increas 2 of temperature, and 
ceasing when on adding a fresh portion, "bet slight change in 
color is produced, or before oe c aractersti¢ odor of the hypo- 
chlorous acid can no longer be readily recognize 
The heavy oil is aepaested from the aqueous solution by fil- 
tration, The latter contains chlorid of mercury, originating 
from the oxyd of that metal employed in the ss = 
hypochlorous acid, also an organic substance, which, 
evaporating the solution, separa arated . as an oil with more or ‘isle 
ecomposition, This is the most interesting of the products 
of the reaction, and in olen is obtain it pure from the solution 
is necessary to avoid the application of a high temperature.
