80 Mr. Howard's Meteorological Journal. [July, 1818. 



REMARKS. 



Fourth Month. — 28. Much dew : at nine a. m. a brisk wind carrying Cumuli, 

 above which appeared beds of Cirrus and Cirrncumulus, moving from SE: a fine 

 day ensued, with Cumulostratus. 29. Fine. SO. Overcast early, with the wind 

 NE; after which wet till evening. 



Fifth Month. — 1. A fine day, save a shower or two. 2. Large Cumuli rose, 

 which in the E especially mingled and inosculated with Cirrostratus above; I sus- 

 pected thunder in that direction: at sunset, Cirri from N to S, above Cirrostrati 

 ranging E and W: rain by night. 3. Drizzling, a. m. : fine, with Cumulus, and 

 Cirrus at mid-day : in the evening, heavy showers appeared to the Nand NE, with 

 much Cirrostratus overhead. 4. Very fine, with Cumuli, and large, plumose Cirri 

 stretcning E and W ; the clouds, though heavy, dispersed at sunset. 5. Sunshine 

 at six a. in. with a few Cirri, &c. : before seven, a sudden mist came on from the 

 E and NE, which obscured the view of the Solar Eclipse during the middle half 

 hour of the time; the dew lay on the grass till noon, in the sunshine, and large 

 Cumuli formed, inosculating with the clouds above: at two p. m. some heavy 

 showers fell, but so local, that the road, half a mile off to the S, remained dusty: 

 in the evening, Nimbi appeared in thunder-groups to the SE and S, and, finally, 

 more extensive rain came on, with the wind SE. 6. Rain, a.m., and at night.

Having left home on a journey on the morning of the 8th ult. I did not witness a 

 very uncommon fall of raiu which took place in this neighbourhood. It com- 

 menced early in the evening of that day, and lasted about 12 hours. Near an inch 

 and a half of water descended in the above space of time, which, taking the 

 shortest course from the higher ground to the hollows, filled the latter several feet 

 deep, and overflowed the roads, in several places not usually subject to this acci- 

 dent. Much inconvenience, and some loss of property, ensued, the particulars of 

 which were detailed in the papers of the subsequent days. This heavy rain spems 

 to have been connected with a change in the general current, which, after a few 

 days further continuance of unsettled weather, became established from the north- 

 ward, the batometer assuminga high level, and the earth drying rapidly. Il wa9, 

 indeed, a singular spectacle to behold the ground saturated with water, and every 

 spring running up to so late a period in the season as the middle of the fifth mouth, 

 when our fields are commonly dry enough, in every situation, to admit of the soil 

 being pulverised by the harrows.
