METEOROLOGY.

[The scite of the Bristol Institution, and the fact of its being closed on Sundays, rendering any me- 

 teorological or astronomical observations taken there both imperfect and incomplete, we avail 

 ourselves gladly of the following " Observatious," of the correctness of which our neighbours at 

 least will entertain no doubt, when we state that they were made by Mr. E. Jones, of Small 



Street.— Eu.] 



The Table for the present quarter, with the exception of the barometrical column 

 as it now stands, having previously appeared, it may be necessary to explain that the 

 barometer used for the tables already published, was situated about forty feet above 

 the river, whilst the instrument now employed is one hundred and fifty, producing a 

 diiierence of about 010 inch, in the mercurial column. 



The temperature is noted by a pair of Rutherford's self-registering thermometers, 

 placed outside a window, fifteen feet from the ground, with an open and unobstructed 

 N. E. aspect. We notice this circumstance particularly, since a comparison with the 

 tables now publishing in London, may lead to an impression that the thermometer 

 used must have been kept in a sheltered situation, from the fact of the minimum 

 temperature being so much higher than in London and its neighbourhood. AVe are 

 warranted in assuming that the climate of this part of the kingdom is much milder 

 than the vicinity of the metropolis, arising from its geographical position ; whilst 

 the same cause occasions a much greater quantity of rain to fall in this neighbour- 

 hood than in London. The difierence is so great as to lead to a supposition that 

 some error must have been committed, did we not know that the care and attention 

 bestowed on this department here, and the character and ability of the registrars in 

 London, render such a circumstance improbable. As an instance, we may mention 

 that in January last, the quantity of rain which fell in Bristol measured 6"30 inch.; 

 in London, the amount registered at the apartments of the Royal Society for the 

 same month, was 0345 inch. In February there fell in Bristol 2'19 inch. ; and the 

 Journal of the Royal Society states, that " during the present month, (February) the 

 amount of rain appears to have been too small to become appreciable in the rain 

 gauge employed."* 



The Pluviometer, or rain gauge employed, is of the kind described by Howard in 

 his " Climate of London," and was made by Bate of the Poultry. It is placed in a 

 garden, at some distance from any building, and about eight inches from the ground. 

 Its situation is N. E. of the city, in its immediate neighbourhood, and at an elevation 

 of about one hundred and fifty feet above the river. 



METEOROLOGICAL ACCOUNT FOR THE YEAR 1834. 



• Since writing the above, we have seen the whole scries of monthly tables for the year 1834, kept 

 at the apartments of the Royal Society in London, by which it appears that the quantity of rain 

 fallen diU'ers so materially from that registered in Bristol, as to make a comparison highly interesting.

i The f|nanlily which fell during December in the preceding year, was 8-93 inches. It therefore 

 appeara, that the quantity registered in London for the whole year, did not amount to so much as 

 that which fell in Bristol in December, 1833.
