REMARKS. 
Third Month.—19. A moderate gale at SW in the early morning, with muck 
cloud carried by the wind. About 10, the wind changing suddenly to NW, the 
whole mass of cloud to the southward became an immense Nimbus, the base reach- 
ing from the SW to the NE, with a lighter sky visible beyond; at the same time 
Precipitation was going on overhead, and we had soon a smart shower mingled 
with hail: the whole ended in a uniform veil of Cirrostratus, and at night we had 
the SW wind again pretty strong. 20, The wind changed again to NW, a.m. 
with much cloud, and some drops of rain. 21.- Fine day: a smart breeze froia 
NW. 22. Fine day.- 23. A trifling shower. 24. Wet, wind, morning: fair day. 
25. A shower with hail at mid-day: a large Nimbus passed, and a distant peal of 
thunder was heard to the NW. 26. Chiefly Cumulostratus : a very little rain,_ 
p-m. 27. Windy, with much cloud, and two or three showers. 28, Clondy: a 
gale through the day. 29. Cloudy, 30. A rainbow at nine, a. m,: squally, with

was sensibly elliptical, the longer diameter being the perpendicular ; it continued 
two or three hours. 3. Large Cirri, with Cumuliz: much dew: very fine day. 
4, Cumulostratus. 5. Fine morning: the hoar frost remained at seven, a.m. on 
some tufts of Saxifraga cespitosa, &c. (as heretofore noticed) long after it had dis- 
appeared elsewhere in my garden ; proving that the warmth which melted it came 
in great part from the earth. 6, Large. plumose Cirri, with Cérrostratus, a.m. 
7. The maximum of temperature for the past 24 hours at nine this morning: thun- 
der-clouds ensued, which soon passed to a quiescent mixture ef different modifica-

rain, p.m.: at evening the wind changed to NW, with a rainbow and a turbid 
mixture of different clouds, 9, Fine, with Cumulostratus: wind N,p.m. 11. The 
clouds this evening were tinged with a strong Jake colour, on the bases of Cumulo- 
strali, beneath Cirrus: some rainattended. 12, Wet, most of the day, 13. Rain, 
a.m, 14, Cumulostratus: in the evening streaks of Cirrus from SW to NE, fol- 
lowed by wind and rain. 15. Clouds followed by rain in the night, as before.
