Meteorological Committee, 1900. 57 
Committee venture to suggest that the Club should pass a vote 
of condolence with the families of the deceased observers ; and 
to the observers who have ceased recording, for their great 
services so ungrudgingly rendered in the past. 
Appendix I. to this Report contains a list of the observers, 
with particulars relating to the stations and gauges, and also the 
monthly tables of daily rainfall, of which a sufficient number have 
from month to month been pulled for the use of the Club. These 
printed tables contain the records of all observers, with the ex- 
ceptions already mentioned, reporting to the Committee. 
Appendix II. contains a record of all falls of rain of 1-00 in. 
and upwards, extracted from the monthly tables in Appendix L., 
and the records of the other stations at the end of this Report. 
It will be noticed that there is only one fall of 2:00 in., and that 
there are only six days with falls over 1 in. 
The Committee do not propose to discuss the rainfall of the 
past year beyond saying that it has been a dry year, and that the 
deficiency in the amount of rain is about 2°50 in. The reason 
of this decision on their part is, that they think that the time has 
arrived at which a discussion of the observations on which so much 
money and toil have been expended may usefully be undertaken. 
Owing to want of time, this discussion cannot be exhaustive, but 
it seems desirable to make an attempt to deal with the problems 
that are revealed by the tables. 
To facilitate this, the mean monthly and annual rainfall for 
the ten years 1891-1900 of all the stations in the district report- 
ing to the Committee have been calculated, and is contained in 
Appendix IIT. This Appendix contains the records of forty-eight 
stations, and is believed to comprise the records of all stations 
in the district having this length of period, with the single ex- 
ception of Kew Observatory. Owing to certain gaps in the records 
of some of the stations, it has been necessary to have recourse to 
interpolation. This method has been adopted with respect to 
Keston, Hayes Common, Sutton, and South Norwood, but the 
gaps in each case amounted to but avery few months. Other 
records are comprised of the figures from two or more separate 
stations either under the same or a new observer. These changes 
have been duly notified from time to time in the printed tables, 
and nothing further need be said about them, except to say that 
no records have been conjoined where the stations are more than 
one mile apart. Slight differences may occur in the elevation of 
the conjoined stations above sea-level, but it does not appear 
probable that this slight difference materially affects the ten 
years’ average. The stations in Appendix III. have been ar- 
ranged in accordance with their height above sea-level, and, 
where the stations are of the same height, in alphabetical order. 
This has been done on what seemed to be the well-founded 
assumption that rainfall up to a certain point—viz. about 1500 ft,
