Methylheptenone. In connection with a short theoretical con- 

 templation of the base CgH^N 1 ) which he had previously obtained 

 from methyl heptenylamine and described, O. Wallach 2 ) reports on 

 a new base C 8 H 16 :NH, isomeric with coniine, which had been pro- 

 duced from the same crude material. It is formed, besides a hydro- 

 carbon C 8 H 14 , by the addition of hydrogen chloride or hydrogen 

 bromide to methylheptenyl amine, and subsequent dry distillation of 

 the addition product. The base has the following properties: boiling 

 point 150 to 15 1°; d 0,823; n D20° 1 A39^] melting point of the hydro- 

 chloride 218 to 220 , of the chloroplatinate 221 to 23 3 . It yields 

 a quaternary iodide of the composition C 8 H 16 N(CH 3 ) 2 I (melting 

 point 242 to 2 43 ), a nitroso compound and a sulphone amide of 

 the melting point 76 to 7 8°. The constitutional formula of the base 

 is probably

Cyclohexanone. O. Wallach 3 ) describes a series of derivatives 

 of cyclohexanone of which the bromine substitution products have 

 already been referred to in our last Report 4 ). The splitting up of 

 cyclohexanone isoxime 5 ) previously described in £-amido-n-caproic 

 acid, could be confirmed by conversion of this acid into normal adipic 

 acid. The reduction of the isoxime with sodium and amyl alcohol 

 led, in addition to acids formed by splitting up the isoxime, to a 

 mixture of bases, from which cyclohexylamine C 6 H 11 NH 2 (boiling
