378 " Miscellanies. 



hydrogen may be considered as a base capable of uniting with water 

 and acids. These resuhs have met with some objections, not in re- 

 lation to the facts themselves, but with respect to the general theory 

 which serves to group them. I now furnish a new example in con- 

 firmation and extension of the laws then deduced. 



There exists in artificial camphor a new carbonated hydrogen dis- 

 covered by M. Oppermann. One volume of this body which I de- 

 signate by the name o^ camphogene, includes ten volumes of carbon, 

 and eight volumes of hydrogen. 



One volume of camphogene and half a volume of aqueous vapor 

 produce essence of turpentine, a combination which in this respect re- 

 sembles sulphuric ether. 



One volume of camphogene and one volume of hydrochloric acid 

 produce artificial-camphor, a composition which thereby resembles 

 hydrochloric ether. 



Camphogene may be combined in various proportions with oxygen. 



One volume of camphogene, united with half a volume of oxygen 

 constitutes ordinary camphor, a combination analogous to the pro- 

 toxide of azote with respect to the mode of union of their elements. 



Common camphor is a base. 



One volume of common camphor and one volume of hydrochloric 

 acid form a neutral hydrochlorate of camphor. 



Four volumes of common camphor and a proportion of nitric acid, 

 constitute the oil of camphor of the old chemists, the bibasic and an- 

 hydrous nitrate of camphor. 



Sulphuric acid agitated with camphor forms more complicated pro- 

 ducts. Chlorine exerts a strong action on camphor, but I have not 

 been able to develop the nature of the products. 



Two volumes of camphogene and five volumes of oxygen pro- 

 duce camphoric acid. 



The form of these determinations would be somewhat changed if 

 the analyses of MM. Liebig and Oppermann should be preferred to 

 my own results. In researches of so delicate a nature, it is difficult 

 to decide. The body which I name camphogene would be formed, 

 according to their analyses, of twelve volumes of carbon and nine 

 volumes of hydrogen. In this case, cholesterine would be a hydrate 

 of that body, the capric and capro'ic acids would be combinations 

 ana-logous to the deutoxide of azote and to nitrous acid. If I am not 

 mistaken, these bodies will belong on the contrary to a new series 

 analogous to that of camphogene.
