the melting point 203 to 204 ; a substance of the same composition 

 and the same melting point was formed when damascenine-S was 

 treated in the same manner. Consequently damascenine is also converted 

 into the isomeric amido acid when boiled with acetic acid anhydride. 

 No new compound was obtained when methyl iodide was allowed to 

 act on the acetyl product. But Pommerehne had already found that 

 the isomeric amido acid from damascenine reacts with methyl iodide. 

 Keller's examination showed that an addition-product 

 C 9 H 10 NO 3 .CH 3 .HI + H 2 O 



of the melting point 172 to 173 , is here formed, which is identic 

 with the one obtained direct from damascenine. Damascenine, there- 

 fore, is also converted by methyl ioide into damascenine-S. From 

 the above compound the new base C 9 H 10 3 • N • C H 3 (melting point 

 1 1 8° to 1 1 9 ) was isolated with sodium carbonate; this base again 

 absorbs one molecule methyl iodide with formation of a compound 

 C 9 H 10 O 3 .N(CH 3 ).CH 3 I + H 2 O, 



which crystallises with one molecule water. 



Both damascenine-S, and the isomeric amido acids, when treated 

 with sodium nitrite in hydrochloric solution, yielded the same nitroso 

 acid C 9 H 10 3 N • N O of the melting point 151 to 152 . 



When damascenine-S was heated for two hours with hydriodic 

 acid of the boiling point 127 and phosphorus to 150 , an amido 

 phenol was formed which melts at 170 , and which is therefore 

 identic with o-amido-phenol. From these results the following 

 formula may be deduced for damascenine-S: — 



/CH3 

 C 6 H 3 ^-NH.CH 3 



in which the methylated amido-group is in ortho-position towards the 

 methoxyl-group. For this reason the isomeric amido acid formed 

 from damascenine is nothing but an o-anisidine-carboxylic acid 

 methylated in the amido-group. 



Nutmeg Oil. In a nutmeg oil recently distilled by us, a higher 

 specific gravity and lower rotatory power were determined than usually. 

 Whereas the properties of nutmeg oil are generally as follows: 

 d 15 o 0,870 to 0,920; « D -j- ii° to -)- 30 ; soluble in 1 to 3 vol. 

 90 per cent, alcohol, — the oil in question had a specific gravity of 

 0,9220 at 1 5 , and an optical rotation of — j — 7 5 2^; moreover it was 

 already soluble in 0,5 vol. 90 per cent, alcohol. These differences must 

 be attributed solely to the quality of the nutmeg worked up; in the 

 present case the quality was particularly good, contrary to the usual 

 distillation quality which consists chiefly of light worm-eaten nuts. The
