REMARKS. 



Tenth Month. — 1. Cirrus, Cirrocumuhis. 2. Cloudy. 3, 4. Cloudy: windy. 

 5. An immense collection of swallows in the evening. 6 — 8. Overcast. 9 — 11. Fine, 

 with the lighter modifications. 12. Foggy morning. The aurora horealis is said 

 to have appeared at night. 16. This day the Cirrus cloud prevailed in an unusual 

 manner, increasing in density until the oblique depending tufts showed dark against 

 a completely overcast sky above : the direction of these tufts was towards the 

 west. IT. Fine: aurora borealis in the evening. (This was observed at Totten- 

 ham by my friend William Phillips.) 18. The first hoar-frost: the tender garden 

 plants, as kidney beans, &c. killed. 19. Overcast. 20. Drizzling, p.m. 21. After 

 rain and a little sleet, it began to snow about noon, falling in very large flakes, thick 

 End rapidly for an hour, and covering the ground : some rain followed. In the 

 evening the wind rose, and it blew hard in ti;e night from about NNW. At mid- 

 night came on a second heavy fall of snow, wii'Ch continued till six, a. in. the 22d ; 

 and though at first much of it melted, it lay in the morning full three inches deep. 

 This day, of course, presenled the appearance of mid-winter, with the single excep- 

 tion of the foliage still remaining on the trees, which, mingled with an enormous 

 burden of snow, presented a very singular and grotesque appearance. The some- 

 what moist state of the snow (as happens also when it falls late in the spring) 

 caused it to be very adhesive, and the frost cementing the masses, the very walls 

 and fences remained thickly coated for some hours; while that on the trunks of 

 trees indicated with precision the quarter from whence it came. Much damage was 

 done, by the breaking down of large limbs from fruit and forest trees in all direc- 

 tions. 23. Snow remained in places the whole of the day ; notwithstanding which 

 I observed swallows about at Stamford Hill. 24. A very white frost this morning -. 

 temp. 31° at eight, a. m. at Tottenham : day w indy, bleak, cloudy. 27, 28. Hoar 

 frost. 30,31. Rainy.
