It seems peculiar that the hydrocarbon 216° Canadian petroleum which 

 gives analytical values corresponding to the formula C10H24 should 

 have the same boiliug point as the corresponding constituent of Penn- 

 sylvania and Ohio oils, and that it should give a chlorine derivative with 

 substantially the same boiling point. Probably a better understanding 

 of this hydrocarbon will be gained in the study of the higher constituents, 

 which is now in progress.
