METEOROLOGY — WATER. 115 



Analyses of mixed paints, E. F. Ladd and Alma K. Johnson (North Dakota 

 8ta. Paint Bui. 5, pp. 57-71). — This is a statement of the composition of com- 

 mercial paints of various brands, which in some instances were obtained on the 

 open market, and in others direct from the manufacturer. Analyses of the 

 pigment and the vehicle are given, and the results are discussed. 



Manufacture of cereal vinegars, W. Hoffmann (Deut. Essigmdus., 14 (1910), 

 Aos. 50, pp. 369, 370; 51, pp. 377, 378). — A description of the processes involved 

 in the manufacture of cereal vinegars, with particular reference to malt vinegar. 



Alcohol formation during sauerkraut fermentation, C. Wehmeb (Coitbl. 

 Bulct. Vctc], 2. Abt., Rcf., 2S (1910), Xo. J,-5, pp. 97, 98; abs. in Chem. Ztg., S'l 

 (1910), No. lJt2, p. 5S5). — It is observed that during the fermentation of cab- 

 bage a certain amount of alcohol is prodi:ced with the lactic acid. 



Potato alcohol in Russia, J. H. Grout (Daily Cons, and Trade RjHs. [U. S.], 

 I'l (1911), No. 22, p. 3'f8). — A report in regard to the progress made in the pro- 

 duction of potato alcohol in Russia. 



Information for distillers and yeast manufacturers, R. Kusserow (Pure 

 /'roduci-s, 6 (1910), \o. 11. pp. (i ',9-652). — This article deals with the im- 

 portance of the proper solution of the nitrogenous substances in mashing and 

 its influence on fermentation, and further, the effect of the addition of sugar 

 to a fermented wort. 



Preparation of caramel, J. J. Hazewinkel (Meded. Proefstat. .Java^Suiker- 

 indus., 1910, No. J/O, pp. Ji97-52Ji). — Tests in regard to the preparation of cara- 

 mel from sugar (molasses, etc.) with llio aid of lime are reporti'd and discussed. 



The report of the agricultural experiment station of the Duchy of Baden 

 at Augustenberg, 1909, F. Mach (Bcr. Grossh. Bad. Landw. Vers. Anst. Au- 

 guHtcnb., 1909, pp. 15 'i). — This is a report of the station activities for the year 

 r.)09. It also contains a history of the station for the last 50 years. 



Agricultural-chemical laboratories in Germany, Holland, and Belgium, 

 I. Lugner (MeddcJ. K. Landtbr. Styr. [Siceden], 1910, No. 5 (152), pp. 29, figs. 

 3). — A brief description of the al)ove-named laboratories, with notes in regnrd 

 to some of the investigations being conducted in them at the present time. 



METEOROLOGY— WATER. 



Meteorological observations, F. A. Stockdale (Rpt. Bat. Card. Brit. Guiana, 

 1909-10, pp. 18-25). — Observations on pressure, temperature, and rainfall at 

 the Botanic Gardens, Georgetown, and at various other places in British Guiana 

 during 1909 and a number of previous years, are recorded and brielly discussed. 



A new sand evaporimeter, A. Demolon and G. Brouet (Sta. Agron. Aisne 

 Bui., 1910, pp. 66-72, fig. 1).—The sand evaporimeter used consisted essentially 

 of a metal cylinder 114 mm. in diameter holding about 3 kg. of sand, which 

 was inclosed in a somewhat larger cylinder containing the water supply and 

 provided with a graduated gauge for measuring the rate of evaporation. 



Observations with this evaporimeter in comparison with a Piche evapori- 

 meter during 7 months are recorded. These show a uniformly higher rate of 

 evaporation from the sand than from a water surface in the Piche evapori- 

 meter. The rate of evaporation was reduced by rainfall and increased by east 

 winds. ■ The evaporation as measured both by the Piche and sand evaporimeters 

 was decidedly greater than the rainfall during the warmer months of the year. 



On the dissolved matter contained in rain water collected at Lincoln, New 

 Zealand, G. Gray (Separate from Canterbury Agr. Col. Mag., 2-', (1910), Nov., 

 pp. 12). — This article reports the results of investigations on this subject during 

 the two years ended June 30. 1909, the investigations being similar to those 

 made by the author in the years 1SS4 to 1SS8.
