Gerber's salt method, ( '. Beger i M'dchw. Zentbl., : 1906 . No. ■'. pp. 1%0-J 

 The author reports favorably upon the use oi this new.method of determining tat 

 in milk. 



The influence of acetic acid and alcohol in gravimetric determinations of 

 the total solids in milk, A. Segin i M'dchw. Zentbl., .' 1906 . No. • •'. pp. 115-119). — 

 The author uses the covers of porcelain crucibles from which the small central han- 

 dles have been broken off, measuring into each cover about 2.5 cc. of milk, and 

 rapidly weighing the sample. The milk is then evaporated over a water bath ami 

 the residue dried to a constant weight in a water oven at 100° C, which requires 

 about 4 hours. No absorbent material is used. 



The time required for drying to a constant weighl was increased by the addition 

 of acetic acid and alcohol and higher results were usually secured. The direct drj ing 

 in small porcelain dishes is recommended as one of the mosl accurate, convenient, 

 and reliable methods for determining solids in milk. 



On the watering- of wine and milk, 1 . Si rre I Ann. Chim. AnalyL, 11 i 190.6), 

 No. 5, pp. 163-165C). The methods given for the detection of added water depend 

 upon the diphenylamin reaction for nitrate-, which is not given by these mat. -rials 

 when pure. 



Collaborative work on tannin analysis, 1'. 11. Small [Jour. Soc. Chem. Indus., 

 .'.-, | 1906), No. 7, pp. 296-298). — This is a brief review of the work of several associa- 

 tions on the methods of estimating tannin. A fairly satisfactory method, the. 

 principles of which are given, has resulted, according to the author, from this 

 collaborative work. The various lines of work of the American heather Chemists' 

 Association now in progress are outlined. 



Miscellaneous chemical analyses made in 1901, A. M. Peter and I.. 0. 

 Beatty {Kentucky Sta. Rpt. 1901, pp. 263 295). — Analyses are reported of 49 samples 

 of sorghum juice, 22 of butter, 27 of sugar beets, 17 of soils, 7 of feeding stuffs, 9 of 

 common salt, 4 of crude petroleum, 1 of marl, 2 of phosphate rock, 4 of clay, 4 of 

 ashes, 2 of tobacco stems, 1 of a tobacco by-product, 5 of tobacco extract, 3 of Paris 

 green, 1 of a commercial substance recommended.for use in curing tobacco, 5of Ken- 

 tucky asphalt rock, 1 of iron ore, and 24 of mineral waters. Determinations were 

 also made of the arsenic in 6 samples of sprayed cabbage. 



Miscellaneous chemical analyses made in 1902, A. M. Peter, L. « ». Beatty, 

 and s. I). Averitt {Kentucky Sty. Rpt. 1908, pp. 283-335). — Analyses are reported of 

 16 samples of sorghum juice, 31 of sugar beets, 10 of butter, 27 of soils, 1 of old wood 

 ashes, <il of grasses and forage plants, t> of soybeans, I of mushrooms, 2 of cotton-seed 

 meal, 1 of a calf food, l of distillers' corn bran, 1 of dried distillers' grains, 5 of dis- 

 tillery slop, 5 of clay, 2 of inter earth. 1 of dissolved hone. I of agricultural lime, 1 of 

 cow manure, and 4l' of mineral waters. 



Miscellaneous analyses, ('. II. Jones and I". M. Hollister | Vermont Sta. /i/'t. 

 1905, pp. 339, 840). — Analyses of a number of miscellaneous materials, including 

 nitrate of soda, dried blood, tankage, hone ( raw and steamed |, acid phosphate, mu- 

 riate of potash, wood ashes, muck, and mixed fertilizers, are reported.
