nearest the ground have been inchidecl. With this deduction, no 

 less than seventy separate records have been preserved, which 

 have been arranged on the same plan as was adopted in the 

 enquiry into the temperature, according to the elevation of the 

 station above sea-level, from the highest to the lowest. 



In the iirst table (Table VII.), the name of every station is 

 included where observations of rain have been taken at any time 

 during the five years, with a distinguishing number affixed to it; 

 then follow the height of the gauge above sea-level, the height 

 of the receiving- surface above the ground, the diameter of the 

 gauge, the total rainfall for each year, and the average annual 

 rainfall where the series has been complete. The succeeding 

 table (Table VIII.) gives the monthly rainfall from about thirty 

 stations for each year. A further selection has been made out 

 of these, where the records have been continuous and the 

 observations in other respects satisfactory. Table IX. includes 

 twenty-one stations ; it exhibits the average monthly and annual 

 rainfall of each separately and with the stations grouped in 

 zones for every 200 feet difference of elevation. The next table 

 (Table X.), which is on a similar plan, records the number of 

 days in the year on which rain fell at sixteen stations, being 

 those where this feature of the climate of the district seems to 

 have been observed with care. The number of stations is less 

 than in Table IX., as it frequently happens, where the rain is 

 the only meteorological element observed, that the fall of several 

 days is allowed to accumulate before being measured, and, 

 although the total deptli may be correct, the record of rainy 

 days is erroneous. Finally, the numbers in Table IX. have 

 been converted into ratios of the monthly to the annual fall, and 

 are given in Table XI. 



In a few instances, when the position was an important one, 

 and the 5-years' register complete aU but a month or two, 

 interpolations have been made on the same system as was 

 adopted for computing the temperature at Waddon, By this 

 method it is assumed that the fall of rain for the months when 

 observations were lacking at a station, bore the same ratio to the 

 depth of rain for the remainder of the year at that station as 

 was observed at the adjoining station or stations where the 

 register was uninterrupted. In every such case, or when any 

 alteration has been made, the figures are given in italics, as are 

 also those for the first nine months of 1881 at Waddon, when a 

 different gauge was used to what was afterwards employed, and 

 in a different position; and for the last five months of 1885, at 

 Botley Hill Farm, where the returns seem incorrect. 



An instructive instance of the importance of securing a good 

 site for the rain-gauge occurred at South Norwood. Here, in 

 1884, the comparatively small annual rainfall attracted attention,
