160 Meteorological Journal. [Aug. 1813. 



REMARKS. 



Sixth Month. — 21. Brisk wind through the day. 22. Wind more gentle. Cu. 

 ntuhstratus and Cirrostratus. 24, A shower about one p. in. 25. The wind 

 inclines to S. E. Clear twilight, somewhat orange-coloured. 27. Cirrus, 

 changing to Cirrocumulus and Cirrostratus: twilight somewhat opaque, but 

 coloured. 28. "Wind N. E. a. m. The Stratus cloud appears to have prevailed 

 in the night. Slight showers at intervals during the day. At seven p. m. several 

 Nimbi, and thunder to the S.W. which, with occasional lightning, passed by 

 S. to N. E. At nine p.m. the air was so loaded with vapours as to deposit 

 water on a glass vessel cooled only to 58-5°. It now began to rain heavily, 

 ceasing at ten, with thunder and lightning still iu the N. 29. Cirrus, CtVro- 

 ttralus, and Cumulostratus. About one p. m. a heavy storm of rain and hail, 

 with several electrical discharges. 30. In the forenoon heavy rain, ushered in 

 by a peculiar hollow sound in the wind, then southerly : p. m. wet at intervals. 

 A part of this day's rain was taken by estimate, the gunge having been left 

 undercover. 



p Seventh Month. — 3. After an appearance of two distinct orders of cloud 

 during the forenoon, inosculation look place suddenly about one, and the Cu- 

 mulostralw:, with a brisk wind, prevailed till sun-set. 4. A slight shower, p. m. 

 From the 5th to the 9th several kinds of cloud prevailed, and occasioned at 

 times considerable indications of rain; of which, however, a few drops only 

 fell, the clouds still passing away to the N. In that quarter on the 9ih, even- 

 ins, we had several distant Nimbi, with the usual appearances of a strong 

 electric charge. A single flash of lightning, and some rain, just discernible in 

 the horizon, were the ouly results. 13. After repeated exhibitions of the Cu- 

 mulostratus, which continued to pass over to the N., we had this night a few 

 drops of rain. 14. Dripping at intervals : the dust laid. 15. A wet day. The 

 vulgar notion that rain on this da's (Which the Popish Calend;irgavetoSt. S within) 

 is followed by the same, daily, for 40 days, if tried at any one station iu this part 

 of the island, will be found fallacious. There is, perhaps, in a majority of 

 seasons, a general tendency to rain during this period, which, in Ireland, and 

 on the western coasts of Britain, may, iu some, produce the effect in ques- 

 tion ; and the prejudice hence arising may have travelled into a climate where 

 it does not hold good. 16. Thunder, p.m. during a shower. 17. A slight 

 shower, p. in. -. dew on the grass. IS. A fine day : the Cumulostratus prevailed, 

 and the evening was very clear, n tth dew. 19. Showers.
