pseudo-phellandrene 
From the phellandrene formula shown, the author still deduces 
the formulae of phellandrene nitrite and nitrophellandrene, on the 
further examination of which he is still engaged. 
Menthadiene. Wallach had on a previous occasion i), by distilling 
dihydrocarvylamine hydrochloride, obtained a mixture of cymol and ter- 
pinene. But when Harries 2) recently distilled the phosphate of this base, 
a new menthadiene was formed, which contained only traces of cymol. 
Harries produced the carvoxime which served as crude material, 
by mixing 100 grams carvone with a solution of 50 grams hydroxylamine 
hydrochloride in 400 cc. methyl alcohol, and leaving this mixture 
standing for 3 to 4 days at the temperature of the room. It was 
then poured into double the volume cold water, when the oxime 
immediately separated out in the form of crystals, in the theoretical yield 
of 98 to 99 per cent. The carvoxime was converted by Wallach's^)
