All fractions showed optical Isevorotation , with the exception of the 

 last one which was dextrorotatory. The fraction in its boiling point 

 corresponded to the terpen e fractions, briskly absorbed bromine, with 

 slight evolution of hydrobromic acid. A more detailed examination 

 of the individual fractions was not made. 



Oil of Pittosporum undulatum. F. B. Power and F. Tutin 1 ) 

 report on the constituents of the essential oil from the fruit of Pitto- 

 sporum undulatum Vent, indigenous to South-Eastern Australia. The 

 crushed fruit yielded 0,44% oil which changed when kept for a prolonged 

 time; d 15 o 0,8165; «r> -f"74°4 / ; insoluble in 10 vol. 70 percent, alcohol. 

 The fractional distillation yielded up to 165 4% d-pinene (nitroso 

 chloride; nitrolbenzylamine, m. p. 123 ). Between 173 and 180 , 

 75°/ limonene passed over (tetrabromide, m. p. 104 ), and between 

 200 and 2 2 5 a body which must probably be regarded as an alcohol, 

 yielding on oxidation a ketone C 9 H u O with a coumarin-like odour. 

 Finally, between 263 and 274 there distilled an optically inactive 

 sesquiterpene C 15 H 24 (di5oo,Q 10; n D2o° 1*5030), fr° m which not a single 

 solid derivative could be obtained, and which is not identical with any 

 of the hitherto known sesquiterpenes. The molecular refraction showed 

 that it is dicyclic, and has two ethylene linkings. There could further 

 be detected traces of palmitic and salicylic acids, and a not determined 

 phenol with a eugenol-like odour, and finally traces of esters of valerianic, 

 formic, and other acids. 



Rose Oil, Bulgarian. This year's distillation commenced at 

 an exceptionally early date and has been accomplished under the most 

 favourable weather -conditions, so that the fears, to which expression 

 was given at the end of the previous season, have fortunately not 

 been realised, and this time again the harvest has given an abundant 

 result. The weather was throughout cool and not too dry, and 

 as a consequence the distillation period lasted a very long time, 

 which, as we know from our own experience, is very advantageous 

 for the yield and for dealing with all the flower-material. According 

 to our informants, this year's production reaches nearly 4600 kilos, 

 which means about 470 kilos more than in 1905. Other reports 

 speak of only 3761 kilos as compared with 3523 kilos last year. A 

 fact is, that after the usual manoeuvres for fixing the prices had been 

 completed, the quotations have been maintained at the same level as 

 in 1905, the producers doing everything possible to compensate themselves 

 to some extent for the continuously growing manufacturing expenses. 

 With the support of the Government, the manufacturers induced the 

 Chamber of Industry and Commerce at Philippople to convene a con-
