intervals diiring tu d iv. At 7 p.in. several Nimbi, and some thunder 
to the S W. which, with occa.sional lightning passed by S. to N. E. 
At 9 p. in. the air was so loaded with vapour as to deposit w ater on a 
gla.ss vc.ssel cooled only to U now began to lain heavily ; 
Ceasing at 10, witn thim.ier and 'ightning still in the N. 29. Cirrus, 
Cirrostratn.s and Ciiimilostratus. /Vboiit one p. in. a heavy storm et' 
rain ami hail, witli .several electrical discliarges. ;}(). In the forenoon 
heavy rain, ushered in by a pecidiur hollow sound in the M'ind, then 
soutlu'rly ; wet at intervals, p. in. A part of this day’s rain was taken 
by e.stiinatioii, tlie giiage having been left under cover. 
Sevfiilh Mouth, ;J. .After an appearance of two distinct orders of 
cloud during the forenoon, inosrnlalioii took place suddenly, about one, 
and the Ciiiniilostratus, with a brisk wind, prevailed till suii M't. 4. .A 
slight shfitver p. m. rroiii the .5tli to the Pth several kinds of eloiid 
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. Ill that quarter, on tlie evening of Ptli we had several distant 
Nimbi, with the usual appe.araiiers of a strong eleelric charge. .A 
single (lash of lightning and some r.iin, just discernible in the horizon, 
were tlie only results, l.j. After repeated exhibitions of the Ciiniulos* 
tratiLs, which continued to pass over to the N. we liad Uiis night a few 
•Imps of rain. 1 1. Dripping at intervals ; the dust laid. 15. A wet 
day. The vulgar notion, that i-ain on this day (by tlie Popbh cahmdar 
given to .St. Switliiii) is followed by the .same daily for forty days, if 
tried at any one station in this part of the islaid will be foumi falla- 
cious. There is in perhaps a majority of seasons, a general tendency 
to rain during this period, 'whicli in Ireland and on the western roa.sts 
«f llritain may, in some, produce the effect in question : and the pre- 
judice hence arising may have travelled into a climate ■where itdoes not 
hold good. 16. Tliiiiider p. III. during a shower, 17. A slight shower 
p. ni. ilcw on the grass. 18. A fine day : the Cnmulostratus prevailed 
•ud the evening was very clear, with dew. 19. Showers.
