METEOROLOGY. 



Report of the meteorologist, L. Metcalf (Massachusetts Hatch Sta. Bpt. 1896, 

 pp. 50-52).- — A brief account is given of the work of tlio year in this department, 

 noting additions to equipment and changes in methods of observation. Apparatus is 

 being arranged "and considerable work has been done preliminary to undertaking 

 at Amherst a series of experiments bearing upon soil temperatures and moistures 

 in their relation to the growth and advancement of crops." 



Report of the assistant meteorologist, W. D. Clayton (Texas Sta. Bpt. 1896, 

 ji/t. 921, 922). — A monthly summary is given of observations during 1896 on atmos- 

 pheric pressure, temperature, rainfall, and prevailing wind, together with the annual 

 averages of temperature and rainfall for 6 years (1891-'96). The average atmospheric 

 pressure for 1896 was 29.73 in. ; average maximum temperature 87.5°, minimum 43.8°, 

 mean 67.7°; total rainfall, 39.65 in. 



The meteorology of 1895 (Trans. Highland and Agr. Soc. Scotland, 5. ser., 8 (1896), 

 pp. 340-347). — A table "gives a comparison of the winds, temperature, rainfall, and 

 sunshine of 1895 as compared with the averages of previous years,'' and the weather 

 conditions during eacli month are discussed in detail, with brief notes on the character 

 of the principal crops of the year. 



The meteorology of 1896 ( Trans. Highland and Agr. Soc. Scotland, 5. ser., 9 (1897), 

 pp. 363-371). — A tabic "gives a comparison of the winds, temperature, pressure, 

 rainfall, snow, and sunshine of 1896 as compared with the previous 40 years' aver- 

 ages," and the weather conditions of each month are discussed iu detail, with brief 

 notes on the character of the principal crops of the year. 



Meteorological observations, L. Metcalf and J. L. Bartlett (Massachusetts 

 Hatch Sta. Met. Buls. 100-102, pp. 4 each). — The usual summaries of observations at 

 the meteorological observatory of the station during the mouths of April, May, and 

 June, 1897, with general remarks on the weather and crop conditions of each month. 



On three French balloon ascensions, G. Hehmites and G. Besancon (Comjit. 

 Bend. Acad. Sci. Paris, 124 (1897), No. 21, pp. 1180-1182). 



The effects of a hailstorm, A. Forel (Compt. Bend. Acad. Sci. Paris, 124 (1897), 

 No. 26, pp. 1549, 1550). — Brief notes on phenomena observed during a hailstorm 

 which did considerable damage, especially to glass. 



The diurnal oscillatory movement of the atmosphere, M. Dechevrens (Compt. 

 Bend. Acad. Sci. Paris, 124 (1897), No. 25, pp. 1479, 1480). — A brief note on observa- 

 tions during several years at Zikawei, China (latitude 31°), which shows that the 

 general air movement at that point is from west to east in the morning, north to 

 south in the middle of the day, east to west in the evening, and south to north in 

 the middle of the night. 



The tornado of June 18, 1897, at Asnieies and the storm phenomena 

 observed on that day, J. Jaubert (Compt. Bend. Acad. Sci. Paris, 124 (1897), No. 25, 

 pp. HS0-1482,fig. 1). 



The tornado of June 18, 1897, L. Teisserenc de Bort (Compt. Bend. Acad. Sci. 

 Paris, 124 (1897), No. 25, pp. 1483, 1484). 



Summary of results of recent studies on atmospheric electricity, J. Elster 

 and II. GrElTEL (Naturw. Rundschau, 12 (1897), Nos. 28, pp. 349-352; 29, pp. 365-367;
