170 Report of the Meteorological Sub- Committee /or 1888. 



Greenwich. On and near a continuous but somewhat irregular 

 line drawn between Leatherhead and Greenwich the rainfall for 

 the month exceeded 7 in. ; being at D'Abernon Chase, 7*22 in. ; 

 Kenley, 9 in. ; Purley, 7'82 in. ; Beddington, 7"15 in. ; Park 

 Hill Rise, Croydon, 7-36 in. ; Dingwall Eoad, Croydon, 7-73 in.; 

 Addiscombe, 7*39 in. ; Bickley, 7*12 in. ; and Greenwich, 

 7"04 in. North-west and south-east of the narrow band in 

 which these large falls were measured the amount diminished to 

 5-24 in. at Surbiton in a westerly direction, and 4-42, 4*54, and 

 4-61 in. on the western boundary of the district at Esher, Rich- 

 mond, and Kew respectively. A deficiency of stations, which 

 will be remedied this year, does not enable similar definite 

 information to be given of the rainfall on the eastern boundary. 

 The smallest depth recorded on that side of the band was 

 5-70 in. at Woolwich. The copious rainfall on the 26th of June 

 was the product of two distinct thunderstorms, the first of which 

 spread over the extreme south of the district, about Caterham ; 

 the other, which occurred between 6 and 8 p.m., passed over the 

 south of London, and was felt most severely in the north-east. 

 The large rainfall on the 1st of August was also associated with 

 a thunderstorm, the brunt of which was experienced at Up- 

 minster, in Essex, some five miles outside our area, where the 

 fall of rain was more than 4J in. Besides June and July the 

 rainfall of March and November was considerably in excess. 

 That of the other months was deficient, being less than half the 

 average in January, May, September, and October. 



Satisfactory progress has been made in the last twelve months 

 in the more even distribution of the stations, but much remains 

 to be done. The Committee trusts that any person willing to 

 aid in the work will communicate with Mr. Bayard, and endeavour 

 to establish rain-gauges at places unrepresented at present. The 

 following may be specified: — Box Hill, Walton-on-the-Hill, 

 Woldingham, BotleyHill, Tatsfield, Cudham, Shoreham, Chels- 

 field, Swanley, Bexley Heath, Erith, Battersea, and Barnes.
