REMARKS. 



Eleventh Month. — i. Misty morning; cloudy: shower at night. 5. Overcast, 

 a.m. : wet afternoon and evening. 6. The drops of dew were frozen, but so 

 clear as not to appear like hoar frost : a tine day, with large Cirri, and afterwards 

 Cirrcslratus and Cumulus : a. stre&ked orange sky at sun-set. 7. Hoar frost, 

 followed by cloudy sky : some rain after dark. 8. Clear morning : hoar frost : 

 about four p. ni. the s!-y became very dark, and there. was a storm of rain, 

 attended by a single loud explosion of electricity. It is remarkable that on the 

 same day of the month last year, at the same hour, and in the same direction, 

 (south-west,) we had a similar storm. 9. Cirrus, with the compound modifica- 

 tions: several shooting stars this evening: windy afterwards. 10. A steady 

 breeze from the N.W. : Cirrostratus appeared over the Thames at sun-rise : ice a 

 quarter of an inch thick, and permanent: a brilliant twilight; first lemon 

 colour, surmounted by purple ; then, by the blending of the two, a riclj deep 

 oran"-e. 11. Hoarfrost. I observe this often continues an hour longer on some 

 tufts of saxifraga caspitosa than any where else in my garden : the plant grows 

 on close spongy masses of fibre, which are bad conductors of heat. 12. It wa» 

 stormy last night ; and is said to have thundered and lightened about three a. m. 

 Wet this morning; but the day fine: twilight orange, delicately varied with dusky 

 horizontal strite. 13. Cloudy and raining at eight a. m., but fine afterwards, 

 -with a smart breeze. 14. Cloudy. 15. Cirrostratus, a.m.: then Cirrus nimbi- 

 formis, depending and curling beneath: a turbid sky ensued, and wind in the 

 right. 16. A wet stormy morning. 17. Much wind by night. 18. Small rain, 

 a. m. : wet and stormy at night. 20. Hoar frost : a little rain at intervals. 

 gl. Overcast. 22, 23. Hoarfrost: miFty. 24. The same: near sun-set a holloflp. 

 ■wind from S. W., and rain in the night. 25. Wet day. 26. Some rain, a. m. 

 27. Clear morning, with evaporation: but before noon cloudiness was coming 

 on from the W., and it rained steadily from sun-set till late at night. 28. Wet 

 again in the night. 30. Large elevated Cirri, with Cirrostratus. 



Twelfth Month.— \> Brisk wind at N. : iu the night a slight sprinkling of mow. 

 3, Wet morning.
