82 Report of Schimmel § Co. April /October 1917. 



Pharmacopoeias. 



American Pharmacopoeia. 



(The Pharmacopoeia of the U. S. of America, 9 th decennial revision.) 



The 9 th edition of the American Pharmacopoeia, which became operative on 

 Sept. 1 st 1916, unfortunately only reached us in the course of this year owing to war 

 conditions, so we had no time to discuss it in this Report, which is in so far a matter 

 of no importance, as all communications with the U. S. are interrupted. We shall 

 remedy this omission in our next Report. • , 



Supplement to the Pharmacopoeia of the German Empire. 



4 th Edition. 



We have not only undertaken the task of discussing at this point the articles 

 referring to our branch of industry, contained in the new editions of pharmacopoeias, 

 but besides we have extended this duty towards publications of a similar nature. To 

 this class belongs the Supplement of the Ph. Germ., ed. V, whose third edition we 

 also criticized from that point of view 1 ). The 4 th edition of the Supplement that appeared 

 last year is now the object of our remarks. 



In distinction to the 3 rd edition, several articles have undergone changes. The 

 following have been left out altogether: valerian oil, oil of bitter almonds, pine needle 

 oil, melissa oil and Ceylon cinnamon oil which has become official. The following 

 have been newly added: carvone, oil of cassia, cubeb oil, cypress oil, eugenol, 

 Siberian pine needle oil, helenine, heliotropine, marjoram oil, menthyl valerate, marnyl 

 salicylate, and American wormseed oil. 



One can in a general manner declare oneself satisfied with the requirements applied 

 to the various oils, 8jc. which have been enlarged by adding data, concerning rotation, 

 in distinction to the former ones; one notices that the criticisms directed against the 

 former edition have not been passed over, and besides, that the latest literature has 

 been consulted. In spite of this, of course, something is left to be desired, as will be 

 apparent from the discussion which now follows. 



The rotation constants invariably refer to an observation temperature of 20°. The 

 strength of the spirits of wine corresponds to the demands of the Ph. Germ., ed. V, 

 ,viz., spirits of wine with 90.09 to 91.29 per cent, by volume and diluted spirits of wine 

 with 68 to 69 per cent, by volume. 



Amber Oil, rectified (Oleum succini rectification). Light-yellow, brownish-yellow, 

 or olive-coloured; d 15 o 0.920 to 0.935 1 ); « D + 22 to +31°; soluble in 4 to 5 vols, of 

 95 per cent, alcohol 2 ). 



*) During recent years, we have observed, in our own distillates, specific gravities up to 0.949. 

 2 ) Up to 7 vols, are in some cases required in order to effect a complete solution.
