37'1' Mr. J. Glaisher's Remarks on the Weather. 



the air passed in this direction over the western and midland 

 counties, the air at the same time passing in al] directions on 

 both sides of this current, particularly on its south side, where 

 it was mostly calm with fog. The 7th, 8th and 9th may be 

 classed as calm days. The 10th being Sunday, I have but 

 few observations. The 11th was calm. On the 12th the air 

 was for the most part in gentle motion, except over the southern 

 counties, where it was chiefly calm. The 13th and 14th days 

 were calm. On coming to the 15th, I find there was a gentle 

 breeze from the N.E. passing over those parts of the country 

 extending from the south coast to Sunderland; north of this 

 place the direction was E. Calm and fogs were registered at 

 Lanark, Glasgow and Dundee. The temperature of the air, 

 which till this day had been mostly above the average for the 

 season, declined considerably below it. On the 16th the pre- 

 vailing direction was N. W., but the air was deflected in many 

 places. The temperature of this day was several degrees below 

 its average, and at night the reading was below 25° at most 

 places. On the 17th the direction of the wind was mostly N.Ei 

 and E. The day was very severe; its temperature at most 

 places was 10° or 11° below the average for the season; and 

 from this time to the end of the month the temperature of the 

 air was low. On the 18th the air was passing in all directions, 

 but chiefly from the N. On the 19th the directions were 

 N.W. and N., and in many places a strong breeze was re- 

 corded. On the 20th there was a westerly current in ex- 

 treme north, a N.W. wind in the northern English counties, 

 and which dispersed in all directions in its progress to the 

 south. On the 21st the air was passing from the N. On the 

 22nd the principal direction was from the W. On the 231x1 

 there was a hard wind from the N.W., storms at some places, 

 with snow and hail falling at others. On the 25th the direc- 

 tion of the wind was N.W., with a sharp frost. On the 

 26th the whole mass of air north of Liverpool passed from the 

 E., and below this latitude its direction was from the N.W. 

 On the 27th the air was in gentle motion from the E. and 

 N.E. at southern places, and from the W. and N.W. at 

 northern places. Snow was falling at several places in the 

 south on the 28tb, the directions were chiefly N. and N.W. 

 On the 29th and 30th the principal directions were S.E. and 

 E., passing with gentle motion on the former day, and there 

 was a gale on the latter. 



The mean of the numbers in the first column is 29*847

 barometer due to the pressure of air; the remaining portion, 

 or that due to the pressure of water, is 0*224 inch. The sum
