"The weather in general pleasant, but marked departure from the average. For 

 the year as a whole, the minimum temperature was somewhat below the usual 

 figure, and the mean daily range a trifle high. The total rainfall was somewhat 

 above the average, as was the cloudiness. For the winter season of 1892-93 the 

 mean temperature was low; while the snowfall was heavy, especially in February, 

 the winter was dry and cisterns were emptied. During the growing season of 1893 

 the mean daily range of atmospheric temperature was a trifle above the average, 

 but that of the soil further below the average. The rainfall was not excessive, and 

 was fairly distributed; coming at haying and at spring plowing time, it retarded 

 farm operations, wliile there was some drought in midsummer. In general, the year 

 was cloudy. The hay crop was moderate, wheat good, oats a little light, and corn 

 considerably below the average, it having suffered from summer drought. In spite 

 of late planting, it matured fully as early as usual."

 subject in Russia.

 tle, C. F. VON Herrmann, and R, Nunn {North Carolina Sta. Weather Service Bui. 

 62, pp. 171-183, charts S). — The usual summaries of observations by the State Weather

 Cient. "Antonio Alzate," 8 {lS94-'95), No. 1 and 2, pp. 5-5).— This is for the year 1893, 

 uniform with similar bibliographies for preceding years by the same author, pub- 

 lished in previous volumes of this journal. 



Observations on dew and frost, R. Russell {Naturwiss. Rundschau, 1893, No. 19, 

 pp. 235-239; abs. in Ccnthl. agr. Chem., 23 {1894), No. 10, p. 6,97).— The author reports 

 independent observations which confirm the conclusions of a number of other inves- 

 tigators that dew and frost are largely produced by the aqueous vapor arising from the 

 earth, and that the aqueous exhalations of plants also contribute to dew formatioxL.
