 (Proc. I'niiis-Mix.sdiiri Dnj J'dniiinf/ Conn., l!)()S, jifi. I!>//-20'), dfjm. 1, map 1). — 

 Tliis paper cDiitaiiis a brk'f statement of the cliaracter of the investigations on 

 the physical conditions of soil and climate in cotniection with crop production, 

 and gives some of the results which have been recently obtained on experimental 

 farms conducted by this Department in cooperation with State experiment stii- 

 tious in the (Jreat Plains area. 



Climate of the city of Buenos Aires (YearhooJ: City Buenos^ Airrft, 17 {1901), 

 pp. 3-50, (Jfjins. 13). — This report contains a brief historical review of observa- 

 tions in P.ucMos Aires, with conii»ilations of the results of these ()l)servations, some 

 of which date back as far as ISOO. The data for 1!>07 include results of obser- 

 vations on pressure, temperatnre, rainfall, humidity, velocity of the wind, sun- 

 shine, and ozone, carbon dioxid, ammonia, and organic nitrogen in the air, as 

 well as bacteriological analyses of the air and determinations of free ammonia, 

 organic nitrogen, and nitrous and nitric acids in the rain water. 



The climate of Abbassia near Cairo, B. F. E. Keeling (Survey Dcpt., Egypt, 

 Paper A'o. 3, pp. (il, pis. S). — This report summarizes observations made during 

 the 35 years ending in 100.3, giving also the mean values for this period. "As 

 far as possible the results have been summarized in the form of tables, the 

 descriptive i)art being confined within the limits necessary for exi)laining them. 

 At the end of the report are given summarized climatological tables, on the 

 plan of the model tables given by Hann in his Climatology. . . . For each of 

 the principal meteorological elements are given the necessary corrections to 

 reduce the means deduced from the present readings made three times a day, 

 to the true daily means publishetl before the closing of the observatory as a 

 first-order station. 



"Two series of charts are given at the end. The first series shows the 

 annual ctn-ves obtained from the monthly means of each of the princiivdl ele- 

 ments, the second shows the mean daily curves." 



The weather of Saxony during 1907 iJalirc^her. Lnndw. Kiiiiiyr. Saeh.'i., 1907, 

 pp. 2-23). — The weather conditions for the year at a number of places in Sax- 

 ony are summarized in notes and tables. The mean temperature of the year 

 was about normal, the highest temperature recorded being 31.9° C, August 6, 

 the lowest, — 2T..">°. .January 2.".. The rainfall was Si!) nun. as compareil with 

 a normal of <iS2 nun. The evaporation was 513 mm. The cloudiness (GO per 

 cent) was about nfU'mal. 



Damage caused by hail in Servia ( Mafrr. Sfatit^. Roj/. Srrhir. 1907. To. 7. /)/). 

 X\l-\-9H, map 1). — Detailed data (in Servian and French) regarding damage 

 caused by hail in Servia from 1X0(5 to 1!M)5 are recorded. 



Amount and composition of drainage waters collected from drain gages 

 during 1906-7, J. M. ITayman (Rpt. Cnirnparc \Iiiilitt] Ayr. Std., 1907, pp. 

 67-H2, pis. 2; ahs. in .Jour. Chnn. Snc. [London], 9', (I90S), \n. 5.12, J J, pp. H90, 

 891). — Data from June 1 to October 31 are given for rainfall, ix»rcolation, and 

 nitrates in drainage water in case of 2 three-foot and 2 six-foot uncropped 

 drain gages built in 10(«. Of the 34..3,S in. of rainfall 10.2 and KJ.T in., respec- 

 tively, percolated through the 2 six-foot gages and 1S.2 and 10.0 in. through 

 the 2 three-foot gages. .Nitrates were remove<l in the drainage in case of the 

 six-foot gages at the rate of 1.S0.3 and 2(K).5 lbs. per acre; In case of the three- 

 foot gages at tlie rate of (HJ.T and S5.<i lbs. per acre. For previous work see an 

 earlier note (E. S. R., 18, p. 815).
