Borneol. In our Report of April 1908, p. 150, we referred to 

 the mode in which 1-borneol was prepared in Tonquin from Blumea 

 balsamifera D. C. (N. O. Compositse). This process has been suggested 

 in several quarters as suitable for the preparation of synthetic camphor. 

 Bacon 1 ) states that the plant occurs profusely in many parts of the 

 Philippines and that attempts have been made in order to obtain 

 camphor therefrom. From the leaves 0,1 to 0,4 °/ of a yellow oil 

 was distilled, which had a camphoraceous odour, consisted of almost 

 pure 1-borneol, and may value from 50 to 75% °f tne pnce of 

 camphor. The tree flourishes very luxuriantly and it is said that the 

 leaves can be collected four times yearly. Experiments in Indo-China 

 have shown that a yield of 50000 kilos of leaves can be obtained 

 per hectare, from which from 50 to 200 kilos of borneol can be pre- 

 pared. It remains to be seen whether, in view of the fact that labour 

 is not cheap in the Philippines, the cultivation and distillation can be 

 carried on there at a profit. 



Fenchyl alcohol. Most investigators have obtained only liquid 

 chlorides from fenchyl alcohol. Kondakow 2 ) alone has succeeded in 

 isolating from it a solid chloride, m. p. 9 2°, which is regarded by 

 Wallach 3 ) as an impure bornyl chloride. In a further article Kon- 

 dakow 4 ) now returns to the question of the haloid-combinations from 

 fenchyl derivatives. * He did not succeed in converting the chloride 

 (m. p. 9 2°) into camphene, and he regards this as a further proof 

 that this chloride is derived from fenchyl alcohol. 



From 1- fenchyl alcohol he has obtained several solid chlorides. 

 One monochloride possessed the following constants: m. p. 22°, 

 d2o° 1,004, Md20° — 8,89°, % 1,4802, mol. refr. found 48,84, 

 calc. 48,88. With alcoholic potash liquor this chloride is converted 

 into a fenchene (b. p. 155 to 160 ; di 8j 5o 0,869; M D — 29,49°; 

 n D 1,468802; mol. refr. 43,57) and into a mixture of liquid alcohols 

 containing fenchyl alcohol or /^fenchyl alcohol. In addition a se- 

 cond monohydrochloride with a b. p. io° higher was formed. The 

 fenchene obtained from the latter possessed the following constants: 

 b. p. 155 to 161°, di 7)5 o 0,868, [«] D — 23,27°, d d 1,468505, mol. 

 refr. found 43,59, calc. for C 10 H 16 /~~ 43,53. Apparently, these chlorides
