Meteorolog-ical observations at the Michigan Agricultural College for 

 1901 {MlchUjan Sta. llpt. 1902, pp. 83-107) .—TahuMed tlaily and monthly summa- 

 ries of observations during 1901 on temperature, pressure, precipitation, humidity, 

 cloudiness, wind movement, etc. The summary for the year is as follows: Mean

Report on the meteorological observations made at the Royal Horticul- 

 tural Society's gardens at Chiswick in 1902, E. Mawley {.Tour. Jloij. Ilort. 

 Soc. [London'\, 27 {1903), Xo. 4, pp. 1073-1081, fitj.^. 3).— The temperature, humidity, 

 and precipitation of each month of the year are reported in notes, tables, and dia- 

 grams. The air temperature is also compared with soil temperatures at depths of 

 1, 2, and 4 ft. 



Report of the Meteorological Council {Bpt. Meteor. Council [Great I>rit((lii'\, 

 1902, pp. 163, 2)1. l,fig. 1, maps 5). — An account of the work of the council during the 

 year ended ^larch 31, 1902, in the lines of ocean meteorology, weather telegrajihy 

 and forecasts, climatology, and miscellaneous investigations is given, with state- 

 ments regarding publications of the council and its library and finances. Informa- 

 tion of a miscellaneous character is given in a series of appendixes. The success of 

 8.30 p. m. forecasts during 1901-2 was, complete 58 jier cent, partial 26 per cent, 

 sum of complete and partial 84 per cent. The averages for the preceding 10 years 

 were, complete 55 per cent, partial 27.1 per cent, sum 82.1 per cent.

 observations on the atmospheric light phenomena, with a view to the study of the con- 

 nection between the optical phenomena and the state of the weather. — p. fireman. 



Rainfall and sunspots, W. J. S. Lockyer {Xature [London'], 68 {1903) Xo. 1749, 

 pp. 8-10; abs. in Science, n. ser., IS {1903), Xo. 446, p)p- 91, 92).— In a note in Science 

 Professor Ward summarizes the author's conclusions as follows: "Smoothed rainfall 

 curves for the British Isles, Brussels, Madras, Bombay, Cape Town, and the Upper 

 Ohio Valley show a long-period variation at all the stations, and further, the occur- 

 rence of the greatest rainfall generally in the years 1815, 1845, and 1878-83, with the 

 minima about the years 1825-30, 1860, and 1893-95. A continuation of the curves, 

 based on the assumption that the apparent law already recognized holds good, indi- 

 cates that the year 1913 will be at about the middle of the next wet epoch. The 

 sunspot curve shows a close correspondence with the rainfall curves. There apjiears 

 to be a long-period solar change of thirtj'-five years, the minimum of sunspots cor- 

 responding roughly with the maximum of rainfall. Dr. Lockyer concludes that 

 'since this long-period rainfall cycle synchronizes so well with the solar changes, the 

 latter may render valuable assistance in determining the epochs of these dry and 

 wet cycles.' " (See also E. S. R., 12, p. 724.)
