21. Breeze: sunshine.

22. The same.

23. About sunset, a body of shallow Cumulostratus, with an abrupt boundary forward, advanced from the E. 24. Cloudy: breeze. 25. The same. 26. The same. 27. The same. 28. Breeze stronger, unsteady: Cumulus. 29. Breeze: Cumulus passing to Cumulostratus, which cleared off at night, leaving a little Cirrus above. 30. Close Cumulostratus, a. m. resembling drapery, as frequent in cold spring weather: p. m. more open sky. 31. Large Cumuli, a. m.: wind SE, gentle: the temperature was 45° at 10 a. m.: the roads are now dusty to an extreme: Cirrus passing to Cirrostratus at evening.

Fourth Mo. 1. Hoar frost: sunshine: Cirri, with haze above.

2. Cirrostratus, with Cirrus: breeze much stronger. 3. Windy: hoar frost Cirrus. 4. Hoar frost: sunshine: Cirrus, with Cumulus: drains emit an offensive gas. (This is a very common circumstance after long settled weather, before a change, and depends unquestionably in great measure on renewed electrical action on the general surface.) 5. White frost: misty from the N: the wind NE: sunshine: at night a lunar halo of the largest diameter: Cirrostratus. 6. The higher atmosphere filling, a, m.: Cirrus, Cirrocumulus, &c.: wind N: a smart breeze: then SW: wind and rain in the night. 7. Dripping a.m.: sleet: cloudy: windy: Cumulostrati, succeeded by numerous Nimbi, letting falling showers of large opaque hail, followed by rain: three distinct peals of thunder, p.m.: one N, another S, and a third near at hand, with lightning. 8. Cloudy: windy. 9. Windy at N, and more so in the night, seemingly from the westward: rain. 10. Cumulostratus: some dripping: rain by night. 11. Obscurity early a. m., with Cirrostratus beneath to S: rain and wind chiefly from the NE: p. m. moderate weather. 12. Sky as yesterday, but the Cirrostratus to NE: rain at mid-day: in the night a gale from NW, with snow for two hours. 13. The high ground to the W and NW is white with snow, a. m.: with us none remains. 14. White frost (8 a. m.), yet cloudy overhead, and a group far to the N, in which were Nimbi: in an hour's time this group reached us, and we had showers of heavy granular snow by intervals. 15. Clear morning: dew: fair, though with Nimbi in sight: very high tides, and much water out in the marshes. 16. A moderate gale at S and SW: some rain by night. 17. Cloudy a. m.: calm: mild. 18. Cumulus, Cirrus: sunshine, with cool breeze.

The mean temperature of this period is full 8° lower than that of the corresponding portion of 1815. It has accordingly presented a striking contrast to the latter in its effects on the vegetable kingdom; not a single day having occurred in it of that which cultivators emphatically denominate "growing weather," when a moist air cooperates with a rising temperature to stimulate vegetable life, and make way for the unfolding of its products.

NOTES. Fourth Mo.

19. Cloudy a. m.: cool dry wind. 20. Warm forenoon about noon, a murmuring S wind, with traces of a solar halo. 21. a. m. Obscurity above, with rudiments of the Cumulus beneath it after this, thunder clouds in the S horizon: rain followed these appearances, and continued during most of the forenoon: swallows appeared to-day: the hygrometer went to 70°. 22. Fine: Cirrus, Cirrocumulus, &c. 23. Very fine day: blue sky, with large Cumuli, and the lighter modifications above. 24. Warm forenoon: a smart easterly breeze p. m.: the hygrometer went to 35°: Cirrus predomi

nated. 25. Brisk wind at NE and SE: the sky clear and pale. 26. Fine day steady breeze. 27. Much dew: clear morning: then Cumulostratus, with a breeze. 28. Dew: clear morning: Cirrostratus appeared, passing afterwards to Cumulostratus: at sunset, Cirrus appeared above. 29. Little or no dew: the sky full of a confused mixture of Cirrus, Cirrocumulus, &c.: some drops of rain, followed by more in the night. 30. Overcast: dripping.

Fifth Mo. 1. Fair. 2. Cloudy at intervals, with a few drops: much Cirrostratus to the westward. 3. Rain at intervals, chiefly in the night. 4. Completely overcast a. m., with Cirrostratus: a wet day. 8. Very rainy p. m., after a little hail about noon. 9. A little rain a. m.: some sunshine p. m. 10. Rainy the whole day. 11. Fair in the evening. 13. A little rain p. m. 17. Very fine day: cool evening. 18. Fair, but cold.

RESULTS.

Prevailing Winds Easterly in the fore part, and Westerly, with rain, in the latter part, of the period.

During this period the leafing of the more forward trees has proceeded, for the most part, under the retarding influence of cold breezes. Twice, the temperature having risen for a few days, the accumulation appears to have gone off in local thunder storms. In travelling on the 17th of fifth month from Bristol to Southampton, I had the opportunity of observing, from a convenient distance, the gradual formation and discharge of a prodigious Nimbus, forming part of a series of clouds, which for several hours continued to pour a flood of rain, accompanied by large hail, thunder, and lightning, on the country about Andover and Winchester. As the sun, which was declining, strongly illuminated these clouds, they reflected a lively copper tint above the indigo ground which marked the heavy rain: the electrical light which fills the striking cloud at each discharge was, therefore, with the stroke itself, imperceptible: but I assured myself of the above-mentioned effects from subsequent information, as we passed over the tract thus plentifully irrigated.

NOTES.-Fifth Mo. 19. Hoar frost: a fine day. 20. Clear morning. 23. Cloudy a. m.: much wind at N. 24. Misty: small rain at intervals. The hygrometer, these two days, noted at 7 a. m. 25. Overcast a. m.: wind at SW: rain, evening and night. 26. Cumulus cloud by day: Cirrostratus at evening. The hygrometer noted at half-past 6 a. m. 27. A wet morning, succeeded by close Cumulostratus through the day. 28-31, inclusive. Fair days.

Sixth Mo. 2. A fine breeze: large Cirri and Cumuli. 3. Cirrostratus prevails, with a cooler atmosphere. 5, 6. Showery. 7-10. Rain. 12. The hygrometer receded to 30°: Cumulus prevailed, and was suc
