Concerning tea, A. D. Maurexbrecher and B. Tollens (Ber. Dent. Cheni. 

 GeselL, 39 (1906). p. SoSl : abs. in Chem. Ztff.. 30 {1906). Xo. 102. Report. .Yo. 

 55, p. Ji62). — Java tea was found to contain 5.0 per cent pentosans on the dry 

 matter basis. By extraction with hot water a trace of fructose, or cane sugar, 

 and glucose was obtained. Hydrolysis with 6 per cent sulphuric acid gave arabi- 

 nose. galactose, and glucose — so apparently araban. galactau, and glucose-yielding 

 carbohydrate are present in tea leaves. 



The carbohydrates of cocoa, A. D. Maurexbrecher and B. Tollens (Bcr. 

 Dent. CJiem. Gesell., 39 {1906). p. 3516: ohs. in Chem. Ztg.. 30 {1906), No. 102, 

 Report. No. 55, p. Ji61)- — Cocoa beans freed from fat and shell, when hydrolized 

 with 4 per cent sulphuric acid, yielded X-arabinose, 5-galactose, and 5-glucose. 

 The shells yielded X-arabinose. 5-galactose. glucose, and xylose. A chlosterin 

 isolated from cocoa butter had a melting point near that of phytosterin. 



Rice, cleaning and polishing, 11. ^IcK. Fulcjham {Bur. of the Census 

 [r. »v.] Bui. 61. pp. '19-58. (Ifjni. 1). — According to the statistical data presented, 

 the total value of the rice products produced in 1905 was $10,290,910, an increase 

 of 80.8 per cent o^•er the values for 19(X) to 1905. Pi'ocesses of manufacture, 

 historical and descriptive data, and other information are presented. 



Beet sugar, Z. C. Elkin {Bur. of the Census [V. 8.] Bui. 61, pp. 59-69).— 

 Statistical and other data regarding the present condition and distribution of 

 the beet-sugar industry in the United States are reported. According to the 

 figures presented the total value of the beet-sugar products in 1905 was 

 $24,^93,794, an increase of 28:'..l per cent over the values for 1900 to 1905. 



Canning and preserving fruits and vegetables, fish, and oysters, E. K. 

 Ellsworth {Bur. of the Census [U. S.] Bui. 61, pp. 9-'i8). — The methods 

 followed in canning fruits and vegetables, fish, and oysters are described. The 

 commercial aspect of the enterprise is discussed with relation to its total amount 

 and present development, the distrilmtion of the industries, and relatetl 

 questions. 



According to the data presented, the value of these canned products produced 

 in 1905 was $108,505,471, an increase of 80.2 per cent over the values for 1900 

 to 1905 and of 9S.7 per cent over the values for 1.S90 to 1900. 



The preservation and ripening of meats, II. Martel {Hi/fj. Viunde et Lait, 

 1 (1907), Nos. 1. pp. 1-1 'i. fifjs. 3; 2, pp. 5.i-61). — The author describes and 

 discusses the different systems of preserving meat by refrigeration and discusses 

 the composition of fresh and refrigerated meat and similar questions. 



The principal systems of preparing and preserving meat in use in the 

 Argentine Republic, S. Baliassakre {Avren. Eeon. Indus. Freddo, 3 {1906). 

 Nos. 29, pp. 997-1011; 30, pp. 1022-102',, figs. 2N).— The Argentine pacldng- 

 house system is described and statistics given regarding the extent of the meat 

 trade. 



Starch sugar (glucose and grape sugar) as a food adulterant, 11. Leffmann 

 {Jour. Amer. Med. Assoe., //,S {1907), No. //, pp. 318, 319). — A summary of data 

 on the use of starch sugar is presented. The author believes that owing to 

 possible contamination with sulphuric acid or sulphites this material may be 

 dangerous and that its use should be forbidden in all cases where it merely 

 cheapens tlie f^od or beverage. 



The microscopical examination of flours and the determination of rice in 

 wheat flour, E. Collin {.Jour. Phitrni. rt Chiin., 6. ser.. 2', {1906), No. 9. pp. 

 S85-395). — The detection by means of the microscope of rice flour, which the 

 author states is often used in the adulteration of wheat flour, is described. 

 Attention is drawn to the fact that sometimes rice flour mixed with beau flour is
