240 VARIETIES OF WEATHER. 



tlie said autumn was rather hot and dry, till 

 about the middle of October, when it became 

 damp, and rather rainy : but still there continued 

 to be an unusual appearance of the clouds 

 during the intervals of fine weather. A similar 

 kind of dry weather occurred again in the 

 spring, 1811, attended with similar phaenomena, 

 and the irregular action of the Aerial Electro- 

 scope. But the summer and autumn following 

 were remarkably fine and wholesome, and very 

 warm, though there w T ere occasionally days in 

 which similar multiform and ever changing 

 configurations of the modifications prevailed. 

 Even showery weather is characterized by very 

 different appearances of the clouds at different 

 times. The stupendous and mountainlike 

 cumuli and cumulostrati, which appear in the 

 intervals of summer Showers, have a different 

 look from those which accompany the cold 

 Snowshowers of spring, with keen March 

 Winds. Indeed, the rocklike Twainclouds, 

 which are seen before such Snow, have 

 generally a well defined, though rugged mar- 

 gin, to appearance, and a peculiar look of 

 transparency, or clearness, which is preserved 

 even when they become dark purple, or nearly 

 black.
