Meteorological Journal kept at Howichy Northumberland, above the Level 

 of the Sea 9 1 Feet, and distant One Mile. 



Mean temperature for the first ten days in March, 43'3°; for the 

 second, 43'8'^ ; for the last eleven days, 42*2°. Barometer for the same 

 periods, 29*22, 29'25, and 29"89 in. Extremes of temperature, coldest, 

 1st, 31"; hottest, 27th, 56^. Depth of rain 1-9 in. Wind easterly 18 

 days, and westerly 13. On the night of the 7th, the aurora borealis dis- 

 played a bright and agreeable aspect. Mean temperature for the first 

 ten days in April, 43'3^ ; for the second, 48*1°; and for the last ten 

 days, 45'S°. Barometer for the same periods, 29*48, 29^68, and 29'35 in. 

 E.Ktremes of temperature, coldest, 4th, 32° j hottest, 15th, 02°. Depth of 

 rain, 1*5 in. Wind easterly 20 days, and westerly 10. Several loud peals 

 of thunder on the 10th; nearest distance H mile. What does this, so 

 early, prognosticate ? There have been no storms to notice in this month. 

 We had favourable weather until the 21st, since which the atmosphere has 

 been obscured by mist and rain, with rarely a glimpse of sunshine. 



The method I have taken for noting my remarks during the last two months 

 will, I trust, correspond with Mr. Gorrie's prescribed plan, although it ought 

 to differ in substance from his, and also from Mr. Rogers's : if otherwise, 

 it will throw aside m}' theory, and render it completely useless and absurd ; 

 but trial is allowed by all to be the most indubitable proof. I am. Sir, &c.
