can be packed and preserved in the same way as the fresh juice. The reduc- 

 tion of the juices to a dry material, while possible, is considered hardly to be 

 commercially practicable. 



A flavoring oil can be prepared from the peel of the Florida orange by dis- 

 tillation with steam at reduced pressure. The colorless oil so obtained, colored 

 by means of the pigment present in the thin outer peel of the orange, is entirely 

 suitable for marketing. Grapefruit peel was found to contain a similar oil, but 

 in such small amounts that its production would not be profitable. 



It is indicated that the juice of decayed fruits, drops, etc., after being 

 sterilized can be fermented for the production of alcohol and the residue used 

 for producing citric acid. The residue from the pulp after the removal of the 

 juice is considered to be suitable for use as stock food. The waste seeds, ground 

 peel, etc., are practically valueless. 



The action of ultraviolet rays on the alcoholic fennentation of India fig 

 must, KoMOLO and Kemo de Fazi {Ann. Chim. Appl. [Rome], 6 (1916), No. 9-12, 

 pp. 221-2Ji6, figs. 13). — The fermentation of fig must by Saccharomyces opuntUe 

 was found to be more vigorous through the action of ultraviolet rays if the 

 time of exposure to the rays was limited. Prolonged exposure caused a gradual 

 diminution of the action of the organism. In the ordinary fermentation of the 

 fig must a heavy film forms on the surface which gradually increases as the 

 fermentation proceeds. No trace of such a film was evident, however, where 

 the fermentation took place under the influence of ultraviolet rays. 



Data are submitted in detaile<l tubular and graphical form and discussed. 



The value of supposed household remedies for vinegar disease in wine, 

 W. J. Babaqiola and F. Braun {Landw. Jahrb. Schtceiz, SO (1916), No. 5, pp. 

 509-525). — Data obtained in a study of the value of veal, carrots, and charcoal 

 as remedies for vinegar disease in wine are reported in tabular form and 

 discussed. The authors strongly advise against the use of these materials, 

 as results indicate that they are ot no value in curing the disease. 



METEOROLOGY. 



Climatological data for the United States by sections (U. S. Dept. Agr., 

 Weather Bur. Climat. Data, S (1916), No. IS, pp. SS9, pis. 2, figs. 5/).— Sum- 

 maries and detailed tabulated statements of climatological data for the year 

 191G are given for each State. 



Meteorological observations, J. S. Stevens (Maine Sta. Bui. 257 (1916), 

 pp. 357, S5S). — A monthly and annual summary of observations at the Univer- 

 sity of Maine on temperature, precipitation, cloudiness, and wind movement 

 during 1916 is given. The mean temperature for the year was 44.83° F., as 

 compared with an average of 42.77° for 48 years; the total precipitation was 

 41.2 in., the snowfall 115 in., the number of clear days 213, the number of 

 cloudy days 101, and the total movement of wind 49,818 miles. 



Meteorological summary, F. Brown (Wyoming Sta. Rpt. 1916, pp. 95-98). — 

 Monthly summaries are given of observations at Laramie, Wyo., during 1915 

 on temperature, pressure, precipitation, humidity, sunshine, and wind move- 

 ment. The highest temperature was 84° F., July 14 ; the lowest —14°, Jan- 

 uary 16. The total precipitation was 12.92 in. The highest relative humidity 

 was 1(X) per cent, January 5 ; the lowest, 27 per cent, July 12. The greatest 

 velocity of wind was 43 miles per hour, November 19. The first killing frost 

 was October 3.
