412 EXPERIMENT STATION RECORD. 



decomposition occurs in water at 100° O., the limit being - reached when 

 the ratio of total phosphoric acid to combined phosphoric acid was 2.8 

 in case of monobarium phosphate and 2.34 in case of monocalcium 

 phosphate. The precipitate formed Mas in every case anhydrous 

 dibasic phosphate insoluble in acetic acid. 



A new gas, ('. F. Brush (Science, n. ser., 8 {1898), No. 198, pp. 485-494, fig. 1; 

 Jour. Amer. Cltem. Soc, i, No.12, pp. 899-912, fip.l).— A paper reail before 



thf American Association for the Advancement of Science, Aifgust 23, 1898, announc- 

 ing the discovery of a new constituent of the atmosphere to which the name 

 "etherion" is given. ''Its chief characteristic thus Jar ascertained is enormous 

 heat conductivity at low pressures." 



Classification of proteids, E. II. Chittenden | Cenfbl. Physiol., 11 (1898), p. 497; 

 abs. in Vrtljsch}\ Client. Nahr. u. Genussmtl., /? (1897), No. i, p. 493). — The author 

 calls attention to the fact that in 1894 he published a classification similar to Wro- 

 Idewski's (E. S. R., 9. p. 480). 



Nitraticn cf cellulose and of its hydro and oxy derivatives, L. ViGNON 

 (Compt. Bend. Acad. Sci. Paris, 126 (1898), No. 23, pp. 1658-1661). — This is a continua- 

 tion of previouswork see p. 407), in the course of which it was shown that cellulose 

 aud hydrocelluloae Yielded small quantities of furfurol and the nitro-oxycellulose 

 large quantities. 



On the determination of phosphoric acid, H. Lasne (Compt. Bend. .lend. Sci. 

 Paris, 127 (189S), Xo. 1, 2>P- 62-64). — The author reports determinations of water- 

 soluble and citrate-soluble phosphoric acid in mineral, raw bone, and degelatinized 

 bone superphosphate which show that small amounts of citrate-soluble phosphoric 

 acid may ho accurately determined by precipitation in the extract it' the solution is 

 allowed to stand 16 hours before nitration. 



Formation of furfurol from starch and its derivatives, F. Sestini (L'Orosi, 21, 

 pp. 109-113; abs. in Jour. Soc. Chem. hid.. 17 (1898), No. 9, p. 861).— Starch heated 

 dry at about 200° C. and in the presence of acids at 100° C. is said to yield furfurol. 



On the Lindo-G-ladding method of determining potash, A. L. Winton and H. 

 J. Wheeler (Jour. Amer. Chem. Sue., 20 (1S9S), No. 8,pp. 597-609).— -This is a paper 

 prepared by a committee appointed by the Association of Official Agricultural Chem- 

 ists of the United States with a view to meeting certain criticisms of the Liudo- 

 G lad ding method of determining potash, notably those of Vogel and Ilaefcke (E. S. 

 R., 8, p. 457). 



Determination of sulphuric acid in wine and vinegar, F. Bimbi (Bol. Chim- 

 Farm., 37, p. 133; abs. in Bui. Soc. Chim. Paris, 3. ser., 20 (1S9S), No. l->. p. 575).

 Heintze (Chem. Ztg., 22 (1S9S), No. 63, p. 632).
