potassium permanganate. The identification of pinene and dipentene was uncertain. 

 The fraction 156 J:o 160° yielded directly a nitrosochloride of m. p. 103° (pinene nitroso- 

 chloride melts at 103°). Dissolved in chloroform and reprecipitated by methyl alcohol, 

 the body had, however, assumed a melting point of 93 to 94° and gave a nitrolbenzyl- 

 amine of m, p. 103 to 104° instead of 122°. This circumstance points to the simul- 

 taneous presence of a second terpene, possibly dipentene, the nitrolbenzylamine of 

 which melts at 110°. 



In the distillation of the Spanish Rosemary Oil, use was frequently made also of 

 other labiates, like spike lavender and sage. The circumstance may account for the 

 varying quality of this oil which in the pure state is said to be better than the French 

 and Dalmatian product. Dorronsoro investigated the authenticated rosemary oils 

 obtained from fresh herbs in blossom from the provinces of Granada, Jaen, Malaga 

 and Murcia. The oils, which had been prepared in the years 1911, 1914, 1915 and 

 1916, had been preserved in well-closed vessels protected from the light. Of the 

 samples, six were feebly dextro-rotatory and two feebly laevo-rotatory: — di 5 o 0.8864 

 to 0.9083; « D i5o — 4°0' to +6° 56'; « D of the first tenth of the distillate —5° 28' to 

 + 5° 30'; n D15 o 1.4672 to 1.5402; soluble in 0.3 vol. to 0.8 vol. 90 per cent, alcohol, 

 in 0.5 to 15 vol. 80 per cent, alcohol (6 oils were insoluble in 70 per cent, alcohol); 

 acid v. 0.57 to 2.08; ester v. 4.6 to 11.8; ester v. after acetylation 28.27 to 81.21; bornyl- 

 acetate 1.61 to 3.88 per cent; total alcohol 7.94 to 28.42 per cent. ; free alcohol 5.39 to 

 25.02 percent. 



The distillation (708 mm.) of an oil from Albunuelas yielded the following fractions: — 

 152 to 163°, 24.3 percent.; 163 to 166°, 17.10 percent; 166 to 170°, 14.6 percent; 

 170 to 180°, 16.6 per cent; 180 to 190°, 9.4 per cent; 190 to 200°, 4.6 per cent; 200 to 

 210°, 5.9 per cent; residue 7.5 per cent The first two fractions gave a good yield of 

 pinene nitrosochloride, m. p. 103°. The fractions 4 and 5 gave the cineole reaction 

 distinctly. From the seventh fraction camphor could be obtained, which soon turned 

 solid. Other products present were acetic acid and isovaleric acid, probably also 

 thymol and linalool. 



The source of the Spanish Oil of Lavender,- as gained particularly in Andalusia, 

 must ascording to Bias Lazaro be found in Lavandula latifolia, Will. (L. spica, L. var. 

 latifolia). Eight lavender oils from Albunuelas, Valencia, Granada, Jaen and Murcia 

 had the following constants: — d 150 0.903 to 0.9161; « D15 o — 3° 28' to + 10°54'; n D150 1.4650 

 to 1.4718; acidv. 1.06 to 3.2; ester v. 5.32 to 14.2; ester v. after acetyl. 90.3 to 106.2; 

 linalyl acetate 1.86 to 4.97 per cent.; total alcohol 26.5 to 31.72 per cent; free alcohol 

 28.85 to 27.95 per cent.; soluble in 1.7 to 2.2 vol. 70 per cent, soluble in 2.7 to 4.3 vol. 

 65 per cent, alcohol. 



From the mountains of Granada, Albunuelas, came an authenticated oil of Lavan- 

 dida Stoechas. L. (cantueso). The product was transparent, reddish-yellow, had a pleasant 

 smell of camphor and the following constants: — di 6o 0.9485; « D -j-36° 10'; n D15 o 1.4768; 

 soluble in 2.6 vol. 70 per cent., in 1 .5 vol. 80 per cent, and in any proportion in 90 per cent 

 alcohol; ester v. 20.95 (corresponding to 7.33 per cent, of bornyl acetate); ester v. after 

 acetyl. 32.4 (corresponding to 3.18 per cent, of free borneol and 9.13 per cent, of total 

 borneol). In the Ladenburg flask at 710 mm. the following fractions were obtained: — 

 180 to 183°, 6 per cent; 183 to 190°, 37 per cent; 190 to 200°, 35 per cent; 200 to 

 210°, 13 per cent; 210 to 215°, 4.5 per cent; residue 4.5 per cent Most of the last 

 fraction solidified; to judge by the form and smell of the crystals the substance was 

 camphor. Dorronsoro further distilled 500 g. of oil at 16 mm. He could not find any 

 terpene in the 5 g. of distillate passing below 100°, nor were there any terpenes
