Mr. J. Glaisher's Remarfcs on (he JVeatlicr. 517 



Latimer, Leeds, Beckingtoii, Aylesbury, &c., and the least 

 occurred at Brighton, Liverpool, Scarva, Torquay, &c. 



The highest reading during the quarter was at Greenwich 

 and Lewishani, which was 71°"5, and the lowest was at Dur- 

 ham, which was S°-8. The extreme range of temperature in 

 England, during the quarter, was therefore 67°'7. 



The average quarterly range of the reading of the thermo- 

 meter in Cornwall and Devonshire was 35°-6; at Brighton, 

 Liverpool and Whitehaven, was 38°' 1 ; at those places situ- 

 ated between the latitudes of 51° and 52° was 51°-3 ; and be- 

 tween the latitudes of 52° and 55° was 4'8°-3. 



The mean direction of the wind was S.W. At Exeter it 

 was N., but this is probably wrong. 



From the numbers in the ninth column, the distribution of 

 cloud seems to have been the same in amount nearly at all 

 parts of the country, and such as to have covered about three- 

 fourths of the sky. The actual amount I believe to have been 

 greater than three-fourths. 



The fall of rain during the quarter has greatly exceeded 

 the average amount for the season, and it has fallen on a 

 greater number of days than usual. At Highfield House, it 

 fell on 71 days; at Helston, on 67 ; at Leeds, on 63; at Fal- 

 mouth, Truro and Saffron Walden, each 60. The places at 

 which rain fell on the least number of days were Hereford, 

 Durham, Thwaite, Newcastle, &c. The places at which the 

 largest falls have taken place, are Whitehaven, Stonyhurst, 

 Truro, Falmouth, Helston, Derby, Newcastle, &c. ; and the 

 places where the fall has been the least in amount, are Wal- 

 worth, Cardington, Saffron Walden, &c. ; generally the fall 

 has been much smaller on the east coast than on the west coast. 

 The average amount for the quarter in Cornwall and Devon- 

 shire was 12 inches, at places situated between 51° and 53^ 

 was 8'2 inches, and at places N. of 53° was 10-7 inches. 



Columns 12 to 16 contain the mean hygronietrical results, 

 and they are as nearly identical as can be expected from un- 

 compared instruments. At Beckington the air seems to have 

 been near saturation. At Hartwell the results cannot be 

 correct; these instruments, however, are to be shortly com- 

 pared with standards. At Leeds the results are evidently 

 erroneous ; the instruments here are to be replaced by new 

 ones. Omitting the results from these places, we find that the 

 mean weight of vapour in a cubic foot of air for England (ex- 

 cepting Cornwall and Devonshire) in the quarter ending 

 March 31, 181-8, was 2*7 grains. The mean additional weight 

 re(|uired to saturate a cubic foot of air in the quarter ending 

 March 31, 1848, was 0*3 "rain. The mean degree of hu-
