ALLISON — ON METEOROLOGY. 397 



red on the last day, but the 22nd was the warmest throughout. 

 Much more rain — 3.90 inches — fell than in this usually dry month; 

 and sixteen days were wet instead of the average eleven. The 

 chief direction of wind at last changed to S. W., with a mean 

 velocity nearly corresponding to that of June. No gale as usual; 

 but seven auroras and seven fogs were recorded, with three thunder 

 storms besides reflected lightning. Acacias blossomed on 22nd. 

 New potatoes not in market till 30th. 



In August high barometers for the season were noted. The 

 mean rising .109 above the average. It was rather a cool month, 

 though the maximum only fell short of that of July by .1, and the 

 minimum of this month was 2° higher than that of its predecessor. 

 The wind continued to prevail from S. W., with nearly the same 

 mean velocity as during the whole summer. The 4.45 inches of 

 rain were slightly in excess; but these twenty days of complete 

 dryness, thus reaching the average of August in this particular. 

 Auroral displays began to decrease, but four were observed. 

 Twice was thunder heard and lightning seen. Six fogs occurred. 

 We had one gale, which was much more violent in Cape Breton 

 and the East, but here was strong through night of 24/25. At 

 thirty-five minutes past midnight it was blowing 34.1 p. hour, and 

 at 1 a. the corrected barometer stood at only 28.867. On 24th 

 there was heavy rain early with thunder and lightning. Rain again 

 heavy from 11.30 a. to 9.45 p., and light showers all night and 

 during day of 25th. A N. gale began 24th, 6 p., veering N. N. E., 

 very strong at midnight and continued 25th till 9 a. when declined ; 

 but the wind was very high all that day, backing to N. W. in 

 evening. 



September pressure was rather great, and the month was some- 

 what cool for the season ; temperature rising however to 85^ on 

 the 28th, and never falling below 38.°5. Still S. W. winds pre- 

 dominated, with a mean velocity of but 5.52 p. hour — the least of 

 any month in the year. The rain was almost identical with that of 

 August, and again rather more than the average. Four auroras, 

 six fogs, two thunders, two lightnings, and one gale were recorded. 

 This latter was not remarkable and lasted but two hours from 

 S. S. E., on the morning of the 5th. There were heavy showers
