On albuminoid substance extracted from maize seed, E. Donard and H. 

 Labbe {Compt. Rend. Acad. >Sd. Park, 1.35 {1902), No. 18, pp. 7 44-7 4(i).— The method 

 of preparation and the chemical properties of a maize proteid, "mazaine," are here 

 described, and an elementary analysis reported. The author states that corn con- 

 tains 4 to 4.5 per cent of tliis proteid. 



On musculamine, a new derivative from muscles, A. Etard and A. Vila 

 {Compt. Jiend. Acad. Vci. Paru, 135 {1902), No. 17, pp. 698-700).— A brief note 

 describing a base prepared from muscular tissue for which the name "musculamine" 

 is {proposed. 



Experiments with Wollny's refractometer for milk analysis, S. Hals 

 {Aarsbr. Offent. Foranstalt. Laudln: Fn-mme, 1901, pp. 402-409). — The WoHny refrac- 

 tometer Avas compared with the Adams method for the analysis of fresh milk, gravity 

 and separator skim milk, watered milk, and adidterated milk of various kinds, in 

 a study of the applicability of the refractometer in milk control stations. It was 

 found that the results with the Wollny refractometer were more accurate than those 

 obtained with the Gerber butyrometric method, and as a rule differed from the gravi- 

 metric results by less than 0.1 per cent. Owing to the great care required in the 

 manipulation of the method, the many different steps, the expense of the reagents, 

 etc., the refractometer is not recommended in preference to the Gerber method in 

 milk analysis where a large number of samples are to be tested daily, as, for example, 

 at milk control stations. — f. \v. woll. 



Proceedings of the first annual meeting of the Association of German 

 Food Chemists {/l^chr. Untt'r.'<ucli. Nahr. n. < lcnu!<.^iidl., 5 {1902), No. 21, pp. 993- 

 1111). — Among the subjects considered at the meeting, which was held at Eisenach 

 in August, 1902, were the examination of Italian pastes and similar materials, the 

 detection of margarin in butter, the detection of fluorin in plants, (|uantitative 

 examination of aqueous solutions by the innnersion refractometer, the (juantity and 

 determination of boric^ acid in plants, the direct gravimetric determination of boric 

 acid in foods, lactic acid in wine, the lecithin content of fats, weed seeds, especially 

 cockle, in meal, and changes in beeswax due to bleaching with chemicals.

 total number of samples examined at the station during the year was 873, including 

 feeding stuffs, fertilizers, soils, and foods. The results of the analyses are given and 

 discussed. Accounts are also embodied in the rei)ort of 7 different series of fertilizer 

 experiments on farms located in the vicinity of Trondhjem. — v. w. woll.
