REMARKS. Fourth Month.-A summer-like day, with a breeze of wind: Cirrus formed about noon, and continued after sun-set, passing to Cirrostratus: some rain followed. 2. Overcast, a. m. apparently with Cirrostratus from Cirrus : during the middle of the day this gave place to Cumulòstratus. 3. a. m. Overcast, calm, with dew on the grass: showers followed: after which Cumulus and Cirrus. 4. Much dew: Cirrus, followed by Cirrostratus: a few large drops about sun-set. 5. Much dew: Cirrus. 6. The same: low Cumuli prevailed afterwards, some of them capped with Cirrostrati: then a shallow bed of Cumulostratus, ending at sun-set in Cirrostratus: the evening twilight opake, dewy, and suffused with red. 8. Cu mulus, beneath Cirrocumulus: a strong breeze: a mixture of Cirrostratus and Cirrus gave the clouds an appearance of active electricity; but the whole ended in Cirrostratus. 9. A confused mixture of the modifications, as yesterday, with the addition of haze: some drops by 10 a. m. and a shower, p. m. 10. Heavy showers, a. m.: cloudy, p.m. 11. Wind, a. m. S. W.: the clouds, mingled with the smoke of the city, came back from the E. at sun-set. 12. a. m. The clouds gathered pêle mêle, the Cumulus capping : p. m. the Nimbus appeared, and after some distant thunder to S.W. we had a shower. 13. à. m. Ĉirrus, Cirrocumulus: much dew, the large drops of which sparkled in the sun with the prismatic colours: various modifications of cloud followed: about one p. m. it thundered, N.: then nearer, with lightning, S.: the wind shifting to that point, we had a heavy shower from W. with hail: wind and rain at night. 14. a. m. Cloudy, windy: Cumulostratus: a little snow: swallows skimming the meadows. 15. Cumulus, succeeded by Cumulostratus: the wind moderate. 16. The same: there were indications of hoar frost this morning. 17. Hoar frost: Cumulostratus: at night Cirrostratus, and a lunar corona. 18. a. m. A few drops during the union of soine clouds, which became Cumulostratus. 19. a. m. Loose Cumulus: at night Cirrus, and afterwards a very large white lunar halo. 20. Overcast, dripping: a hail shower, p. m.: at night a lunar halo, very small, the prismatie ring touching a Corona within. 21. Much cloud and wind: wet forenoon and night: the greatest depression of the barometer that has occurred in the present year. 22, 23. Much cloud, windy: rain at intervals. 24. Windy: cloudy: rain, a. m. with a little hail: in the evening the Cumuli dispersed rapidly, with Nimbi and Cirrostrati in the horizon. 25. Various clouds, ending in rain, of which, however, very little till night. 26, 27. Windy, variable: some dripping. 28. A little rain early: then Cumulostratus. 29. Cumulostratus: strong breeze: dripping: the Cirrocamulus appeared, transiently, as for several days past: a Stratus at night. 30. Cirrocumulus, which passed to Cirrostratus: p.m. (upon the wind becoming S. E.) rain. RESULTS. Winds variable, but for the most part Northerly. Barometer: Greatest height......
