Annual weather summary, 1893, J. (>. Lee {Louisiana Stas. Bui. 

 29, 2d ser.,p. 104ti). — A tabulated summary of observations during each 

 month at the North Lonisiana Station on temperature, rainfall, etc. 

 Tlie highest temperature, 97°, was recorded on June 20, July 20, August 

 3, and September 15; the loNvest, 18°, on January 10 and 20. The

Meteorological summary for Utah, 1893, J. Dryden {Utah 

 iSta. Kpt. IS'Jo^pp. 257-271). — Tables give (1) the daily readings of the 

 maximum and minimum thermometers and the daily range for the 

 year; (2) a daily record of the relative humidity and dew-point for 

 7 months of the year ending October 31 ; (3) a daily record of the 

 readings of the barometer and attached thermometer; (4) a summary 

 of the pressure, temperature, dew-i)oint, relative humidity, precipita- 

 tion etc., for the past 3 years; and (5) the mean temperature at 

 several diftereut localities in the State. The summary for the year at 

 the station (Logan) is as follows: Average air pressure, 24.90; highest 

 temperature, 98° F. (July 19) ; lowest, —10° (February 1) ; mean, 40.82°; 

 relative humidity, 00.22; dew-jioint, 47.42; i)recipitation, 14.51 in. 



"Tlie year is remarkable for the coldness of the month of February and the late- 

 ness of the spring, farm work being fully 2 weeks later than in 1892. The mouth 

 of December was unusually mild, and somewhat made up for the low average of 

 February. 



" The precipitation for the year amounted to 14.51 in. The summer months, or 

 growing months, were extremely dry, and this, with the lack of heat in the spring, 

 rendered the season very unfavorable to agriculture, especially to dry farming." 



Meteorology, practical and applied, .J. W. Moore {London : F. J. Hebvian, lSD4,pp. 

 44'), illd. Part 1 of a xanitarii scries). — This is atreatise on meteondogy in general, with 

 applications in part 4 to sanitary matters and diseases, the latter part including only 50 

 pages. As a meteorology it is well and pleasantly written, and is noteworthy in 

 the United States for containing the most complete account of the develoiiment and 

 work of the meteorological service of the States which has yet been published. To 

 this subject over 50 pages are devoted in the text, and in Appendix 1 is given a list 

 oJ' the regular stations of the United States Weather Bureau, and in Appendix 2 the 

 more important publications of the United States meteorological service. Although 

 printed in London, the book is adapted to the demands of the public in North 

 America also. — M. w. Harrington. 



The sun and agriculture, with an appendix on the moon, F. Houdaille 

 (Leaoleil et Vas/ricnltenr arec un appcndice siir la June. MontpelUer: 1893, pp. 542 ; S2 

 iUuHtralions). — Professor Houdaille intimates in his preface that his title is ''per- 

 fidiou;-,," and that it should read "Meteorological Ideas for Agriculturists," but that 

 he chose the title used in order to have the book read. It gives a simple and inter- 

 esting statement of the source and distribution of light and heat and their relations 

 to animal and vegetable life— as they Avere understood 10 or 15 years ago. Lunar 

 iiiliuences are discredited. The book is attractive in appearance and style, and a 

 similar book (but fresher and less diffuse) might serve a good purpose in English. —
