[P.] Campliene [177] when heated 

 with phosphorus pentoxide gives an 

 oily product, which may contain cymene 

 (Heusler's ' Chemistry of the Terpenes/ 

 Pond, p. 59). 



[Q.] From menthene [178] by heating 

 with anhydrous cupric sulphate at 250 

 (Briihl, Ber. 25, 151). 



7. Styrene (p. 33). 



To be added to synthetical pro- 

 cesses : 



[A, p. 33.] The formation of styrene 

 from nascent acetylene and benzene in 

 presence of aluminium chloride is con- 

 firmed by Parone (Journ. Ch. Soc. 86, 

 I, 26 ; from I/Orosi, 25, 148). 



9. Dipentene and Limonene (p. 36). 



The presence of this hydrocarbon in 

 neroli oil is confirmed by Hesse and 

 Zeitschel (Journ. pr. Ch. [2] 66, 481) 

 and by Walbaum and Hiithig (Ibid. 

 67, 315)- The last-named authors (Zoc. 

 cit.} confirm also the presence of di- 

 pentene in petit-grain oil from Para- 

 guay. For further reference to the 

 occurrence of 1-limonene in verbena oil 

 from Verbena triphylla see Theulier, Bull. 

 Soc. [3] 27, 1113. 



13. Methyl Alcohol (p. 40). 



The cohobation water of oil of savin 

 from Jumperus sabina and the distilla- 

 tion water from the oil of W. Indian 

 sandal- wood contain methyl alcohol 

 (SchimmePs Ber. April, 1903; Ch. 

 Centr. 1903, 1, 1086). The presence 

 of methyl salicylate and benzoate in 

 ylang-ylang oil is confirmed (Ibid.}, 

 and the occurrence of methyl anthrani- 

 late in this same oil recorded (Ibid.}. 

 Methyl salicylate is a constituent of 

 the oil of cassia flowers from Acacia 

 cavenia and A. farnesiana (Walbaum, 

 Journ. pr. Ch. [2] 68, 235), and methyl 

 anthranilate a constituent of the essen- 

 tial oil of tuberose blossoms. This last 

 oil, when obtained by ' enfleurage ' 

 instead of by extraction with petro- 

 leum, contains" also methyl salicylate 

 (Hesse, Ber. 36, 1459). Methyl an- 

 thranilate has been found in petit-grain 



oil from Paraguay (Walbaum and 

 Huthig, Journ. pr. Ch. [2] 67, 315: 

 for estimates of the quantities of 

 methyl anthranilate and other con- 

 stituents of average oil of neroli see 

 further Hesse and Zeitschel, Ibid. 66, 

 481). 



To be added to synthetical pro- 

 cesses : 



[D, p. 44.] Formic aldehyde gives 

 methyl alcohol by catalytic reduction 

 by hydrogen in presence of finely 

 divided heated nickel at 90 (Sabatier 

 and Senderens, Comp. Rend. 187, 301). 



[P, p. 44.] For the industrial pro- 

 duction of methyl alcohol (and formic 

 aldehyde) by the electrolysis of sodium 

 acetate in presence of sodium chlorate 

 see Moest's Germ. Pat. 138442 ; Journ. 

 Ch. Soc. 84, I, 546. 



[L, p. 44.] Camphor [175] gives 

 methyl iodide among other products 

 when heated with strong hydriodic 

 acid at 200 (Markownikoff and Gor- 

 benko, Ber. 30, 1216). From methyl 

 iodide through methyl acetate followed 

 by hydrolysis, or by any of the usual 

 methods. 



14. Ethyl Alcohol (p. 44). 



Further researches on anaerobic, intra- 

 molecular alcoholic fermentation in 

 sugar-beet have been published by 

 Stoklasa, Jelinek, and Vitek (Beit. ch. 

 Physiol. u. Path. 3, 460 ; Zeit. Zucker- 

 Ind. Bohm. 27, 633), and in peas in 

 potassium nitrate solution with dextrose 

 or peptone by Nabokich (Ber. deutsch. 

 bot. Gesell., 21, 398; Ch. Centr. 1903, 

 2, 1012). Further studies of the en- 

 zymes from the cells of the higher 

 animals and plants which produce this 

 fermentation have been undertaken by 

 Stoklasa and Czerny (Ber. 36, 4058). 

 According to Cohnheim (Centr. Physiol. 

 17, No. 17) and to Batelli (Comp. Rend. 

 137, 1079) this alcoholic fermentation 

 by supposed animal enzymes is due to 

 micro-organisms. 



With reference to selective fermenta- 

 tive action in connexion with stereo- 

 chemical configuration (pp. 46-47),

 rinck and Mucor aUcrnans ferment mal-
