Generally speaking, the values given above lie within the limits which 

 had been previously observed in the various copaiba balsam oils by the 

 firm in question. Only in isolated cases of Cartagena oils was the optical 

 rotation much lower this time. The authors attribute this to the botanical 

 derivation of the balsams, as no adulteration was discoverable. 



Heliotropin. When heliotropin (piperonal) is dissolved in acetic 

 anhydride with the addition of a drop of cone, sulphuric acid, there 

 results, according to Blanksma 4 ), a compound called by him piperonylidene 

 diacetate, consisting of colourless crystals, m. p. 80°, which also occurs 

 in a highly labile modification, melting at 51°. 



Menthol. According to a report by Dr. Miiller, interpreter at the 



Imperial German Consulate General at Yokohama 2 ), the export of menthol 



from Japan in the year 1909 amounted to 102411 Kin, value 490525 Yen 

 (1908 = 55406 Kin, value 262937 Yen).

The above figures show at a glance that in the course of the past year 

 the exports have sensibly increased. In the view of our correspondents 

 this is principally due to the fact that, especially in the second half year, 

 the musk brought to market was of particularly good quality, as a result 

 of which a strong demand was experienced, in the first place from Paris, 

 the leading centre of the perfumery industry, and, in the next, from London 

 and New York. Hence the traders in the interior sent large parcels of 

 their better qualities to market. The natural consequence of increased 

 business has been that prices have become firmer, a condition which will
