 species proves to be 8. sodiroana Hack, de- 

 scribed from Ecuador, tbe determination hav- 

 ing been confirmed by Professor Hackel him- 

 self: 



This is by no means an isolated case of the 

 occurrence of identical species in Ecuador and 

 Guatemala, but it has peculiar interest from the 

 marked character and rarity of the plant con- 

 cerned (p. 50 ) .

MONTHLY WEATHER REVIEW 



Nos. 5 and 6, Monthly Weather Review, 

 1907, contain the following articles of the 

 most general interest: 



" Guilbert's Rules for Weather Prediction," 

 by Dr. Oliver L. Fassig. Guilbert prepared 

 a paper for the competition organized by the 

 Belgian Astronomical Society, " in order to 

 bring out the present state of the art of pre- 

 dicting the weather." 



"Principles of Forecasting the Weather," 

 by Gabriel Guilbert, of Caen. This sets forth 

 the method followed by the writer, which is 

 based on the principle of the normal wind. 

 Those who are interested in weather forecast- 

 ing, either practically or theoretically, will 

 find this discussion worthy of serious atten- 

 tion. 



" The Eelation of the Movements of the 

 High Clouds to Cyclones in the West Indies," 

 by J. T. Quin; a further contribution to the 

 discussion by the late Father Benito Vines, 

 prepared for the Chicago Meteorological Con- 

 gress of 1893. 



"Memorandum on the Gulf Stream and 

 the Weather," by Professor Abbe; a sane 

 statement of the extent to which the Gulf 

 Stream does not affect our weather. 



"The Cold Spring of 1907," by Professor 

 A. J. Henry; a review of the weather map 

 features which produced the cold weather of 

 last spring, coupled with the following : " The 

 underlying causes of the recent cold weather 

 are probably obscure and deep seated." 



" Value of Weather Forecasts to Natural 



Gas Companies," in which the importance of 

 forecasts of colder weather, with increased 

 need of gas, is emphasized. 



"Tornado at Wills Point, Texas, May 25, 

 1907," illustrated by two snap-shot photo- 

 graphs. Such photographs, although still 

 rare, are fortunately becoming more nu- 

 merous. 



"Eelations of the F. S. Weather Bureau 

 to the Eailroad Man," an address delivered 

 by H. W. Eichardson, local forecaster at 

 Duluth, Minn., before the Northern Eailway 

 Club; contains notes on many interesting 

 phases of the relation between weather and 

 railroading. 



" Legal Decisions as to Cyclones," being the 

 opinion in full, of Judge Philips, of the 

 United States Circuit Court of Appeals, . 

 Eighth Circuit, Minnesota. 



" Hythers and the Comparison of Climates," 

 by W. F. Tyler; a discussion of the question 

 of sensible temperatures. 



"Foehn in New South Wales," an extract 

 from an account published in 1837. 



« The St. Swithin's Day Fallacy," by J. H. 

 Morrison. " It would seem to be almost use- 

 less to say anything further regarding the 

 absurdity of the old superstition, with such 

 an array of tell-tale figures all set against the 

 legend." 



" The Santa Ana of California," quotation 

 from Professor Geo. E. Hale (An. Vol. Car- 

 negie Inst., 1906). 



"Equinoctial Storms," by Professor E. B. 

 Garriott. " There is no one special storm to 

 which the term 'the equinoctial' should be 

 applied." 



FORESTS AND RAINFALL 



Dr. J. Schubert, director of the meteor- 

 ological section of the Prussian Forestry 

 School at Eberswalde, has recently published 

 the results of his continued studies on forest 

 influences in two papers. In one of these 

 ("Der Niederschlag in der Setzlinger Heide," 

 1901-5; Zeitschr. f. Forst und Jagdwesen, 

 1907, No. 8) it is pointed out that of seven- 

 teen stations in forest, on the forest edge and 

 in the open, the forest stations show a greater 

 precipitation (1901-5), and the stations in the
