Meteorological Observations made at Clapton, 9235 
Windmill-street, or by applying to Mr. Brande at the 
Royal Institution. 
Mr. Singer has put to press ‘*Elements of Electri- 
city and Electro-Chemistry, including Voltaic Kiec- 
tricity or Galvanism.”? The new System of Insulation, 
discovered some time since by Mr. Singer, and mentioned 
in a former Number of this Magazine, will, we under-

Meieorological Observations made at Clapton in Hackney, 
from July 24 to August 16, 1813. 
July 24.—Showery cirrus of confused kind, cirrostratus 
-and cumuli of rocklike and mountainous appearance as 
usual. Soon after noon I observed the ewmuli in the SE 
of acopper colour; shortly after there formed a thunder 
shower, which came up from the SW ; afterwards it cleared, 
with wind in light gales, but the thunder showers came on 
again at times. 
July 25.—Rapid showers with west wind; in the clear 
intervals | noticed the usual phzenomena, cumuli sailing . 
along, and smaller ones in their vicinity lost, while the 
Jarger were augmented When very large volumes of 
cumulus came near they grew darker, drew together, and 
cumulosivatus iormed.. In a case of this kind about noon, 
the cumult so changing ceased to move on in the direction 
of the wind; portions seemed visibly attracted towards the 
centre of the mass; and cumulostratus with its denser struc- 
* ture and continuity of base was the consequence. 1 noticed 
at the same time misilike cirrus above in small quantity. 
Presently all the cwmuli which came up put on the cumu- 
lostratonus appearance, while the aforementioned denser 
mass increased in blackness, and went on to a state of 
nimbus*. In the intervals of the showers the wind blew 
rather strong in gales. Thermometer at midday 70°, at 
11 P.M. 55°. Barometer 29.65.—N.B. The showers 
today were very partial; there were none at Ewell in 
Surry, but a hard storm at Boxhil!, six miles distance. 
July 26. —Rapid and frequent showers in strong gales
