15. — Thr Rainfall in 1875. 



[Summary of Quarterly Reports read 10th June and llth Nov. 1875, and 13th Jan. 1876 ] 



The following table shows the monthly fall of rain, in 1875, as 

 recorded at Watford House by Dr. Brett, at Har wood's Farm by 

 Mr. Swanston, at Cassiobury House by the Earl of Essex,* at 

 Oaklands, Hempstead Iload, by Mr. Edward Harrison, and at Nash 

 Mills, Hemel Hempstead, by the President, Mr. John Evans, F.ll.S. 

 The localities are grouped, firstly, under the river-basins, in 

 accordance with the botanical districts into which Mr. 11. A. Pryor 

 has divided the county ;f and secondly, according to their distance 

 from Watford and their proximity to each other, — an arrangement 

 the advantage of which will be more apparent if reports are 

 received from more distant parts of the county. The reports for 

 the first quarter of the year, previously published in the ' Transac- 

 tions,' J are incorporated, and the mean monthly fall at Nash Mills in 

 the decade 1860 — 69, computed as before, is given in the last 

 column. 



*Absence from home havinj^ prevented the Earl of Essex furnishinf^ returns 

 for the first four mouths in the year, the means of the amounts recorded at 

 IJarwood's Farm and Oaklands for these mouths are inserted in brackets.
