than referred to being the product of Chamaecyparis obtusa Endl., a native 

 of Japan. We are now in a position to describe the oil of a second species, 

 Chamaecyparis Lawsoniana Pari. (Cupressus Lawsoniana A. Murr.), a stately 

 coniferous tree, often found in German gardens. This oil was distilled by 

 ourselves. The distilling material, which came from Holstein, yielded about 

 1 °/o of a lemon-yellow oil of an odour reminding of oil of savin or of cypress. 

 Its other properties were as follows: di 5 o 0,9308, « D + 23° 48', n D20O 1,48844> 

 acid no. 3,7, ester no. 61,6, ester no. after acetylation 78,8, soluble in V 2 its 

 vol. of 90°/o alcohol, with 1 to 3 vols, passing turbidity. With bisulphite 

 we succeeded in isolating small quantities of an aldehyde which, judging 

 by its odour, was perhaps identical with laurinic aldehyde. 



Camphor from Cinnamomum glanduliferum. R. S. Pearson, of 

 Dehra Dun, has obtained from the leaves of Cinnamomum glanduliferum, 

 a laurel-tree growing in the districts south of the Himalayas, a camphor 

 which must probably be regarded as identical with the Japanese commercial 

 product. A sample of the crude product, which has been sent to us by 

 Mr. Pearson, possessed a m. p. of 175°, which was raised to 176° after 

 recrystallisation from dilute alcohol. The sp. rotation of the purified 

 camphor in 55,55 °/o alcoholic solution (90%) was [«] D + 46,32°; in a 

 43,91 °/o solution of xylene [«] D + 49,12°, falling to [«] D + 48,72° after the 

 solution had been allowed to stand for 10 days. The oxime melted at 

 118° and, as was to be expected, rotated in the opposite direction, that 

 is to say, to the left. When boiled with acetic anhydride no alcoholic 

 constituent, such as borneol, could be detected; the crude product, there- 

 fore, consisted only of d-camphor. 



Oil of Dacrydium Franklinii. A distillate obtained from the wood 

 of Dacrydium Franklinii Hook. f. (D. huonense A. Cunn.) has been sent to 

 us from Melbourne, Victoria. The tree, which belongs to the Conifers, 

 is known there as "Huon Tree". The oil was of a pale yellow colour 

 and had a pronounced odour of methyl eugenol, which, in fact, forms its 

 principal constituent. di 5 o 1,0443; « D + 0°6'; n D20 o 1,53287; acid no. 0,9; 

 ester no. 1,5; soluble in 5,2 vols, and more of 60°/o alcohol; the dilute so- 

 lution showed a faint opalescence. In distilling, the greater part of the 

 oil passed over between 251 and 253° [754 mm (98 to 100° at 2 to 3 mm.)] 

 and proved to be methyl eugenol, which was identified by conversion into 

 veratric acid (m. p. 179 to 180). The oil also contains traces of eugenol 

 (benzoyl compound, m. p. 70°). The methoxyl determination gave the 

 high methyl value of 164,3, from which the methyl eugenol content was 

 calculated as 97,5 °/o, but in reality it is probably a little less. 



Oil of Eugenia apiculata. In Chili a drug known locally as "arrayan" 

 is used in diarrhoea and in affections of the lungs, for which purposes it 

 is said to enjoy a high repute among the natives. According to Tunmann 1 )
