161-229). — In this artic'le the author reviews the i)reseiit status of the use of 

 sulphurous acid in wine making, particularly in the manufacture of red wine, 

 introducing into his discussion facts obtained in laboratory investigations and in 

 commercial experience. The first part of the discussion is devoted to a <oii- 

 sideration of the antiseptic action of sulphurous acid on the vitality of the 

 yeast, and the second part to its action upon the alcoholic fermentation and the 

 (piality of the wine. Attention is also given to forms in which the acid may be 

 useii, the economy of the process of sulphiting, and some of the causes of fail- 

 ure. An api)endix reports results of experiments relative to the action of sul- 

 phurous acid on the color of wine. 



Handbook of potato drying, E. Pabow (HandbKch der KartoffeltrockncrcL 

 Berlin, nm, pp. VIII +210, />/.s\ 9, flun. .')).— 'Phe iwtato harvest in Germany for 

 years has been increasing more rapidly than the consumption in usual ways 

 as food, for production of starch, brandy, etc. A considerable portion of the 

 excess yield is now dried, the dried product being used as a feeding stuff and 

 in various technical industries. 



This volume presents and discusses a large amount of information on the 

 industry of potato drying. A large section is devoted to descriptions of pro- 

 cesses and apparatus employed, and another to consideration of the results 

 of investigations by numerous authors on the value of the dried potatoes for 

 food, feeding stuff, raw material in technical industries, etc.

 {Handbmik ten dienste van de i:iuikerriet-Ciiltuur en de RietHuiker-Fabrirdj/c 

 op Java, Amsterduni, 1901, pt. 3, pp. XXIV-\-Ji.'i9+XX). — This volume coni- 

 1 irises part 3 of a handbook for use in the culture of sugar cane and the 

 manufacture of cane sugar. Part 1 includes chemical methods of investigation 

 of the Java cane sugar industry, and part 2 a discussion of the enemies of 

 sugar cane (E. S. R., 19, p. 552). In the present publication the author pre- 

 sents a summary and discussion of chemical knowledge regarding sugar, its 

 raw material, and its manufacture. 



Evaporator scale, S. S. Peck (Hatcaiian t<ugar Planters' Sta., Div. Agr. and 

 Cliem. But. 21, pp. 31). — An attempt has been made to ascertain whether data 

 obtained in research by various investigators on the solubility of phosphates of 

 lime, alumina, and iron, and of sulphate of calcium, in water and salt solutions 

 under various conditions could be put to practical application in lessening the 

 amount of scale formed in or on the tubes of the effects in the mills of Hawaii. 

 The results obtained, as reported in this bulletin, offer no precise solution to 

 the problem, but they explain some of the phenomena of scale formation. 



Chinese albumin manufacture, W. Martin {Daily Consular and Trade
