A dash denotes, that the result is included in the next following observation. REMARKS. Third Month.-19. A moderate gale at SW in the early morning, with much 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 reaching 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 from 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. Cloudy: a gale through the day. 29. Cloudy. 30. A rainbow at nine, a. m.: squally, with showers: the bow again twice about three, p. m. 31. Cloudy: some drops of rain. Fourth Month.-2. A lunar halo at night, of large diameter, and colourless: it was sensibly elliptical, the longer diameter being the perpendicular; it continued two or three hours. 3. Large Cirri, with Cumuli: much dew: very fine day. 4. Cumulostratus. 5. Fine morning: the hoar frost remained at seven, a. m. on some tufts of Saxifraga cœspitosa, &c. (as heretofore noticed) long after it had disappeared elsewhere in my garden; proving that the warmth which melted it came in great part from the earth. 6. Large plumose Cirri, with Cirrostratus, a,m, 7. The maximum of temperature for the past 24 hours at nine this morning: thander-clouds ensued, which soon passed to a quiescent mixture of different modifications, and rain came on at evening. 8. Much Cirrostratus, with pretty heavy 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 lake colour, on the bases of Cumulostrali, beneath Cirrus: some rain attended. 12. Wet, most of the day. 14. Cumulostratus: in the evening streaks of Cirrus from SW to lowed by wind and rain. 15. Clouds followed by rain in the night, as before. 16. After a fine day with clouds, rain in the early morning. a. m. 13. Rain, NE, fol INDEX. ABERRATION of light, on the maximum of, 377.
