mentioned in { British Rainfall,' we gather that in 1872 the greatest 

 quantities for that year, as compared with the other three, fell at 

 fifty-six stations out of eighty-two, of which forty-five gave the 

 maxima for the years 1848 to 1872. Iu the year 1852 sixteen sta- 

 tions furnished the greatest falls, fifteen being maxima from 1848 

 to 1872. In 1848 the largest falls were at eight stations, five being 

 maxima as above. In 1860 there were only two stations at which 

 the falls were the greatest for the four years named ; there were 

 no maxima at any of the eighty-two stations in 1860. Mr. Symons 

 gives a supplementary Table of seventeen stations, at each of which 

 the maximum rainfall occurred on other years than the four wet 

 years discussed. The figures quoted from, and the quantities re- 

 corded in the Table of comparison mentioned show that in the 

 majority of cases 1872 was generally the wettest year on record. 



Weekly Weather Reports issued by the Meteorological Office. 



"We are glad to find that the Meteorological Office has resumed 

 the issue of "Weekly Summaries of the Weather in "Western Europe. 

 It is intended to accompany the chart issued on Wednesdays by a 

 summary of the weather during the previous week, so that each 

 day's map will be more readily intelligible when examined by the 

 light thrown upon it by the summary, the course of a depression 

 more easily traced, and the general character of the weather much 

 better understood than it can be from the mass of figures comprised 

 in the daily reports. There is, however, one feature which we are 

 desirous should be introduced ; it is a publication of monthly baro- 

 metric curves at selected pairs of stations some distance apart from 

 each other, as, for example, Haparanda and Biarritz, Christiansund 

 and Scilly, Cuxhaven and Valencia, Toulon and Stornoway. If 

 each pair of curves were projected on the same line of abscissae, the 

 ordinates would show at a glance the direction and amount of the 

 gradients for the period of projection, say, one month. We have 

 no doubt that one or two pairs of curves introduced monthly would 

 greatly facilitate certain meteorological inquiries, and indicate the 

 course to pursue in reference to other stations.
