eugenol and its esters were exposed to light no polymerisation was ob- 

 served. When to a solution of ethylisoeugenol in acetic anhydride potas- 

 sium nitrite was added it yielded, after prolonged standing, needles with 

 m. p. 85°. The corresponding treatment of diethyldk'soeugenol in glacial 

 acetic acid solution resulted in dk'sonitrosoethyHsoeugenol. 



Wassermann's 1 ) experience with regard to the polymerisation of 

 ethyleugenol is explained by Puxeddu by a previous transposition of 

 eugenol into tsoeugenol. Ethyleugenol is produced when ethyl sulphate 

 is allowed to react with a solution of eugenol in a 10 p. c. potash solution. 

 It occurs as an aromatic oil, b. p. 254 to 255°. d 0O 1,0260. When ethyl- 

 eugenol is heated in a reflux condenser to 270° there results a polymeride, 

 m. p. 140°, which is not identical with diethyldiisoeugenol. 



Myristicin. isomyristicin dibromide, a characteristic, derivative of 

 myristicin, has been treated by E. Scandola 2 ) in concentrated methyl- 

 alcoholic solution with sodium methylate, the result being the production 

 of the «-ketone of isomyristicin (m. p. 90 to 91°; m. p. of the semi- 

 carbazone 180°). When isomyristicin dibromide is heated upon the water 

 bath with aqueous acetone solution it first yields «-hydroxy-/?-bromo- 

 dihydroisomyristicin, which in turn, when heated with alcoholic potash 

 liquor, gives rise to a glycol (CuHi 4 5 ). The latter, when warmed with 

 glacial acetic acid with the addition of a few drops concentrated sulphuric 

 acid, yields the /^-ketone of isomyristicin (m. p. 55°; m. p. of the semi- 

 carbazone 143 to 144°). 



When a solution of isomyristicin is boiled in glacial acetic acid with 

 the addition of a few drops of concentrated sulphuric acid, it gives rise 

 to a small yield of a crystalline body, m. b. 232 to 233°; perhaps a poly- 

 meride of isomyristicin. 



Similar reactions of ?sosafrol have been investigated by Hoering 3 ).

A paper by J. Bredt 4 ) dealing with cis- and ^raws-camphoric acid 

 diamide, chlorocamphor nitrilic acid and camphoric acid dinitrile cannot 

 be dealt with in detail here owing to want of space, and we must there- 

 fore restrict ourselves to a brief synopsis. Bredt, by acting with ammonia 

 upon camphoric acid dichloride, obtained 1. camphor-sec. -terf.-nitrilic acid 

 (a-camphor nitrilic acid) (m.p. 152°) and 2. cis-trans-camphorlc acid diamide 

 (m. p. of the hydrated product 132°, of the anhydrous body 160°). Treat-
