750 EXPERIMENT STATION RECORD. 



the name gliadin. Wheat gluten he con^iiders to l)e made up, therefore, of 3 distinct 

 proteidn well charaoteri/ed by their cleavage products, namely, gluten casein, insoluble 

 in alcoliol; gluten fibrin, slightly soluble in cold tiO° alcohol; and gliadin, readily 

 soluble in tliis reagent. 



Concerning- the precipitation of pure glycogen, Z. Gatix-Gruezwska {Arch. 

 riii/sl'J. [rjlih/cr], 100 {lOO.i), No. 11-12, pp. 034, i>o5).—X preliminary communica- 

 tion in which the author notes that pure glycogen prepared from horseflesh is pre- 

 ci}titated by alcohol from an aqueous solution in two different forms, viz, spheres 

 and rods. The character of the precipitate, in his opinion, affords a means of judging 

 of the purity <>f the glycogen. 



On a new product of the autodigestion of pancreas, F. BaUiM {Beitr. Chem. 

 riii/niol. u. Pathol, 3 {1903), pp. 439-441; <ibs. in Bui. Hoc. Chim. Paris, 3. ser., 30 

 {1903), Xo. 23, p. 12S9). — The autodigestion of pancreas was continued from 5 to 6 

 weeks at a temperature of 37° C. A new product was isolated, for which the author 

 proposes the name "scatosino" because of its probable relations to skatol. 



New studies on scatosine, R. E. Swaix {Beitr. Chem. Phy.'^ioL n. Pathol., 3 {1903), 

 pp. 442-44S; ahs. in Bui. Soc. Chim. Paris, 3. ser., 30 {1903), No. 23, p. 1289).— A 

 chemical study of the scatosine mentioned above. 



liOss of nitrogen from urine by evaporation, BtJRKi {Schvjeiz. Landw. Zisehr., 

 31 {1903), No. 39, p. 938; abs. in CenthJ. Arjr. Chem., 32 {1903), No. 12, p. 846).— In 

 evaporating to dryness the nitrogen of a sample of urine declined from about 0.8 per 

 cent to 0.08 per cent. 



Further notes on the phosphorous constitutent of plant seeds, E. Schulze 

 and E. Winterstein (Ztxrlrr. PhijsiuJ. Chem., 40 {1903), No. 1-2, j'P- 120-122).— A 

 cliemical study of a phos])horous body in the seeds of Sinapis nigra. 



Concerning the lecithins prepared from plants, I, E. Schulze and E. Winter- 

 stein {Ztschr. PJiysiol. Chem., 40 {1903), No. 1-2, pp. iW-2i5).— The authors prepared 

 and studied lecithin from lupines and from vetch, paying especial attention to the 

 portion of the lecithin which is difficultly soluble in alcohol. 



Investigation of the seeds of Polygala apopetala, E. W. Hilgard {California 

 Sta. Rpt. 1902-3, jtp. 102, 103). — The possi])ility of using for oil-making the seeds of 

 Poli/r/ala apojietala, which is a native of the lower region of California, is discussed, 

 and analyses (by G. E. Colby) of seed and partial analyses of the roots are reported. 

 The seeds were found to contain over 56 per cent of oil, which when extracted by 

 ether was found to have a strong flavor of saponin. The cold-pressed oil was of a 

 lighter color than olive oil. When washed with water, dried with calcium chlorid, 

 and filtered, the taste of saponin disappeared and the oil was bland. Comparative 

 tests showed that the oil is more liquid and less drying than olive oil. 



The author does not regard it probable that P. apopetala can be grown with profit 

 as an oil-producing jilant unless the oil is found to possess some special merits or 

 have uses not now known. 



Miscellaneous analyses, G. E. Colby {California Sta. Rpt. 1902-3, pp. 98, 99). — 

 Brief statements are made regarding the examination of a number of samples of 

 oranges, wines, olive oils, gluten foods, poisoned foods, etc. 



Report of the Agricultural Chemical Institute at Bern, 1902 {Landw. Jahrh. 

 Schweiz, 17 {1903), N'o. 10, j)p. 543-553). — Analyses were made during the year of 

 2,299 samples of fertilizers, 1,247 of feeding stuifs, 199 of soils, and 139 of miscel- 

 laneous substances. The results of the analytical and inspection work during the 

 year are suminarized and a brief outline is given of the experimental work conducted. 



Report of the Agricultural Chemical Institute at Zurich, 1902 {Landw. 

 Jahrh. Sehweiz, 17 {1903), No. 10, pjp. 5.5-^-,5C5).— This is an extract from the annual 

 report of the institute and consists of a sunmiary of the results of analyses of 1,801 

 sanq)les of fertilizers, 1,043 samples of feeding stuffs, and 283 of miscellaneous 

 materials.
