FOODS NUTRITION. 495 



In the test of the effect of the colors upon the skin only 2 were found to be poison- 

 ous, namely, Ursol (/ and Auraniin n, the effect of the former l)einji much the more 

 pronounced. In the author's opinion, with the data at present availalile no relation 

 can be traced between the chemical classification of the coal-tar dyes and their 

 physiological and toxicological properties. It should be noted, however, that he, as 

 well as other investigators, did not tind that any of the red dyes were poisonous. 



Compositioii of East Indian foods according to analyses made in the labor- 

 atory of the Colonial Museum at Haarlem, M. Greshoff and J. Sack ( Bui. 

 Kolunutal Muk. Haarlem, lyO.i, jS^o. ~\s', Sup.). — In continuation of earlier work" by 

 the authors and J. J. van Eck, analyses of 100 samples of East Indian food materials 

 are reported in tabular form, together with brief descriptions of the samples. 



The composition of Indian food materials, M. Greshoff {Chem. Zig., 27 

 {1903), No. 4~, ]ip. 499-501). — Analyses are reported of 200 food materials from the 

 Dutch East Indies, mcluding cereals, legumes, flours, starches, ])read, pastry, seeds 

 and fruits, edible fungi, preserves and pickles; fresh, dried, and preserved fish and 

 meat; oysters and other sea food; eggs of different sorts, edible birds' nests, and 

 miscellaneous food products. 



Some of the fruits, fresh and preserved, which were analyzed follow: Bananas, 

 dates, box myrtle {Myrica sapida), durian {Durio zibethinus), Indian mulberry 

 {Morinda cilrifolia), Gnetum gnenion, Arerrhoa carambola, Bouea inacropJiylla, and 

 Zalaccn edidis. These analyses were made under the author's direction by J. Sack 

 and J. J. van Eck, and the present account, which includes only analytical data, is 

 a summary of material which has been reported in publications of the Haarlem 

 Koloniaal ^Museum (see above), later figures being given in a few instances. 



Concerning plum jam, R. Wov {Ztvlrr. Oeffentl. Chem., 8 {1902), pp. 270, 271; abs. 

 ill Hyg. Rundschau, IS {1903), No. 15, p. 793). — Three analyses of plum jam are 

 reported. 



Nut menu, A. S. Flowers {Mount Joy, Pa.: Author, 1903, pp. 42, ph. 7). — A large 

 number of recipes are given for the preparation of \'arious dishes from chestnuts and 

 other nuts. The value of nuts as food is also briefly discussed. 



Cocoa and chocolate, C. B. Cochran {Penns^jlvania State Ikpt. Agr. Rpt. 1902, pt. 

 1, pp. 662-679, ph. 4 ) • — Cacao beans, chocolate, and other cacao products are described, 

 as well as their principal chemical constituents, the object being to present data useful 

 for the detection of adulterants. The author also gives information concerning several 

 adulterants of cocoa butter, ' ' chocolate glazing, ' ' and the starches used as adulterants 

 of chocolate. 



Analyses of salt {Connecticut State Sta. Rpt. 1902, pit. 4, p- 4-^4) ■ — Analyses of 4 

 brands of salt are reported. 



Some food products and food adulteration, E. F. Ladd {North Dakota Sta. Bui. 

 57, pp. 249-315). — In compliance with the State Pure Food Law, analyses were made 

 of a number of samples of camied fruits and vegetables, vinegars, and flavoring 

 extracts. The detection of sulphites and formic acid in canned goods when the man- 

 ufacturers state positively that such materials had not been added leads the author 

 to suggest that possibly these materials are added to fresh berries by producers and 

 shippers. " Future investigations must determine whether this supposition is cor- 

 rect." The use of saccharin is briefly discussed. 



Seventeenth annual report of the Ohio Dairy and Food Commissioner, J. 

 E. Blackburn {Ohio Dairy and. Food Com. Rpt. 1902, pp. 100). — In addition to the 

 financial report of the State dairy and food commissioner, statistics are given of the 

 number of foods and condiinents examined, and the results of the examination.
