1863 H. Watts Dict. Chem. I. 724 A camphene often yields several isomeric modifications by treatment with different acids, or by repeated treatment with the same acid. The new camphenes thus produced are called camphenes of the second order, or sometimes campherenes. Another class, called camphenes of the third order, or sometimes camphilenes, are obtained by the action of lime or baryta at high temperatures on the hydrochlorates of other camphenes.
