Storm on Fune 23rd, 1878. 33 
of smaller hail and rain. Ina few minutes the roads were rushing 
rivers; the hilly streets became like mountain torrents, the beds of 
which were torn up and deposited on the level ground at the bottom, 
a notable instance being seen in Coombe-street, where the surface of 
the road was totally destroyed and converted into a series of deep 
trenches and hillocks of sand and stones. 
At 3.45, or 40 minutes after this portion of the storm commenced, 
I emptied the gauge again, and found that there had fallen in that 
time 0°89 of an inch. 
After this I only measured 0°02, which fell in the form of slight rain, 
while the fourth and last part of the storm exerted its fury in the S.E. 
The total fall of rain in the 23 hours from 1.30 to 3.45 p.m. was 
1°82 inches, and o'o2 from 3.45 to 4.45 made a total of 1°84.

The fall fron 2.5 to 3.45 p.m., a space of 1 hour and 4o minutes, 
was 1°67 inches. 
I find that at Waddon House (P. Crowley, Esq.), 2°15 was 
registered; at Tanfield Lodge, Southbridge (J. Weston, Esq.), 1°90; 
and at Addiscombe only 1°41, or a difference between Waddon and 
Addiscombe of 0°74 of an inch. 
The tremendous force of such an enormous weight of water 
falling in so short a space of time will be best realised by comparing 
it with the heavy fall on the roth and 11th of April last, when a 
great deal of flooding was caused by a fall of 1°95 inches in 19 
hours. On this occasion we have had nearly as much in two hours 
and a quarter. 
On the 3oth of July, 1872, there fell 1°14 inches during a storm 
which lasted half-an-hour ; on the 23rd of the same month 0°55 fell 
in 20 minutes, and on the r1th of the same month 0°46 in 20 minutes. 
On the 24th of September, 1875, there fell in 14 hour during a 
thunderstorm 1°13 inches. 
On the 25th and 26th of July, 1867, in 24 hours there fell 2°58 inches. 
On the r1th and rath July, 1868, in 24 hours there fell 2‘03 inches. 
; a the 23rd of September, 1871, there fell in the night 1°55 
inches. 
During the whole of this remarkable storm the horizon to the 
south of Croydon appeared to be almost clear, and I understand 
that at Caterham Junction, two miles to the south, no rain fell. 
At Camden Town, N.W. of London, full three inches of rain fell 
in the three hours.

16, Wandle Road, Croydon, 
June 25th, 1878. 
At Nantwich House (Park Hill Rise) the fall was only 1°28, whilst 
that at the Filter Works at Brimstone Barn, to the west of the town, 
was 2°22 or a difference of nearly an inch.
