REPORT — 1866. 



Lastly, to take a short group of years, the fall at Ware, in Hertfordshire, 

 may be taken at 25 inches, we then get the following results : —

This accordance is specially satisfactory for two reasons, it proves at once 

 the safety of the plan suggested, and the reliability of these old observations. 



Eainfall 1864 and 1865. 

 Tables V., VI., and VII. continue the series of detailed rainfall tables com- 

 menced in 1860, and are arranged exactly as in previous years. The exces- 

 sive drought of 1860, and its locality of greatest intensity, are shown very 

 markedly by Tables V. and VI. Lengthened comment on the returns is un- 

 desirable, but it may be well to mention that the drought of 1864 prevailed 

 only in England and Ireland, and that its greatest intensity was in the eastern 

 counties, where many stations had less than 15 inches in the whole year. In 

 July 1864 there was considerable drought, many English stations having less 

 than a quarter of an inch ; in October, on the contrary, there was an exces- 

 sive rain in the south-east of Scotland amounting in Roxburgh to more than 

 the fall in the previous nine months. September 1865 was the driest month 

 that has occurred for some years : at 129 stations the faU was under a tenth 

 of an inch, and at 48 no rain fell at all. October, however, was wet through- 

 out the country ; the ordinary fall in that month is 11 or 12 per cent, of the 

 yearly total, in 1865 it was about 30 per cent.
