26 EXPERIMENT STATION RECORD. 



A gas or saturated vapor thermo-regulator, H. Parent v ;iud R. Bkicaud {Compt. 



Bend., 122 (ISOi'!), Xo. 17, pp. 'J19-'J22). 



A new method of converting sulphates into chlorids, P. Jannascii {Ztachr. 

 aiioryait. Clwm., 12 {ISUG), No. 3, pp.222, 224). — Tho sulphate is fused with boric 

 aiihydrid until fumes of sulphuric acid are uo longer given off, the fusion being dis- 

 solved in hydrochloric acid. 



On the composition of the red pigment of Amanita, A. 15. Giuffiihs {Compt. 

 Mend., 122 {IS'Jo), No. 23, p. 1342). — Tho results of analysis indicate the formula 

 Ci.iHisOh. The name Anianitin is proposed. 



On a new reaction for asparagin, L. Moulix {Jour, rharm. et Chim., ser. 3, IG 

 {1S9(>), No. 11, p. r,43). 



Detection and separation of the acid principles of plants, L. I^indet {Compt. 

 Bend., 122 {1S96), No. 20, pp. 1135-1137). 



A new cooler, R. Lasne {Ann. Chim. anal. appUq., lS9i'>, p. 145 ; aha. in Chein. Ztg., 

 20 {1S96), No. 42, Repert., p. 149, fuj. 1). 



Device for maintaining constant level of liquids in receptacles, A. Matiiot 

 {Jour. I'liann. et Chim., ser. 3, 16 {1896), No. 12, pp. 594, 595, Jig. 1). — A balanced T-tube 

 connected with a water supply, one arm emptying iuto a waste pipe, the other iuto 

 the receptacle. From the latter a float is suspended, from the former a weight. When 

 water Hows through the tube it will empty into the receptacle until the float rises 

 and tilts the tube, when it will flow into the waste pipe, and rice versa. 



A w^ashing apparatus for the determination of nitric nitrogen according to 

 Kiihn, O. Forster (6'/(em. Ztr/., 20 {1S9G), No. 39, p. 3S3, Ji;/. 1).—A sipbou-tube device 

 for preventing alkali from being carried over in distillation. 



Handbook for the biochemical laboratory, J. A. JMandel {New York: J. Wiley 

 and Sons, 1S9C,). 



Short introduction to the analysis of raw^ materials and manufactured prod- 

 ucts of agricultural and fat industries, W. Kai.man {Kurze Anleilung ziir chemisclien 

 Untersuchung von Bohstoffcn und Producten dcr LandwirtschaftUchen Gewerhe nnd der 

 Fettindastrie. Leipsic and Vienna: F. Deutick, 1S96, pis. 3). 



Proceedings of the tw^elfth annual convention of the Association of Official 

 Agricultural Chemists, H. W. Wiley ( U. S. Dept. Agr., Division of Chemistry BuJ. 47, 

 pp. 172, figs. 2). — This is a detailed account of the proceedings of the convention held 

 at Washington, September 5, 6, and 1, 1895. A brief account of this meeting has 

 already been given in the Record (E. S. R., 7, p. 169). 



Seventh report of the agricultural chemical experiment station at Tabor, 

 Bohemia {pp. 172, pis. 3). 



BOTANY. 



On the action of different colors upon plants, O. Flammarion 



{Bui. Min. A(/r. France, J 5 {1S9(j), Xo. :2, pp. ;273-377, Jig. i).— The effect 

 ofgrowiug various plants under red, green, blue, and clear glass lias 

 already been partially reported by the author,' but the results are given 

 in greater detail in this bulletin. The following experiments were not 

 referred to m the previous publication. 



Maize was planted under the different-colored glass mentioned above, 

 and the growth in height and weight per plant was, under white glass, 

 1.2 meters, weighing 111 gm.; under red glass, 0.0 meter, weight 7.5 

 gm.; under green glass, 0.25 meter, weight 3.5 gm.; while under blue 

 glass there was no growth.
