jQ^ Mr. George Corden. 



The most noteworthy features of the year were the fall of 

 i-q. inT (or nearly two inches) in 19 hours on the loth and 

 iith of April, and the remarkably heavy thunderstorm of he 

 l\rd o June when, in 2i hours there fell at this station the 

 enorr^ous quantity of 1-84 ins. (hail and ram). Some idea of 

 thenature'of the downpour of rain on ^h- occasion may be 

 gathered from the fact that between 2.20 and 2.35 p.m., or in 

 ?5 mmutes, 0-41 ins. was deposited-equal to i-6o ins. per hour, 



'^-^aSn^th^faut ofTain of less than an inch in their regular 

 sequence as to date, we have, on March 28th, a heavy snow 

 storm yielding 0-83 ins. On June 8th, durmg a thunder 

 storm' rain felffor an hour at the rate of 8-64 ms. in 24 hours 

 On July 26th, during another thunder storm, for ef^ minutes

METEOROLOGICAL REPORT FOR 1879. 

 In drawing up this report and the tables which accompany 

 it I have made use of the observations taken at Addiscombe, 

 aAd kindly placed at my disposal by Mr. Edward Mawley 

 F M.s! hi^meteorological station being, for the purpose I 

 have in view, the best equipped in this neighbourhood. 

 Position of the Instruments, &c. 

 The cistern of the barometer is 210 feet above sea-level 

 The shade temperature thermometers are suspended in a 

 Stevenson's screen, 4 feet above grass, m a freely exposed 

 position. The solar^radiation thermometer is mounted on 

 the top of a post 4 feet above grass, with its bulb directed 

 owards the I.E. The terrestrial-radiation thermometer is 

 Ix^osed on the most open part of the lawn, w^th its bulb jus 

 touching the blades of grass. The temperature of the soil s 

 taken wkh a Symon's earth-thermometer, the bulb of which is 

 one foot below the surface of the lawn. The funnel of the 

 rain-gauge is 9 inches above a level piece of grass, in a clear 

 site, and 202 feet above sea-level. The cups of the self- 

 recording anemometer are 50 feet above the ground, and 15 

 eet above the roof of the house. Jhesunshme recorder s
