CHAP. 8. VARIETIES OF WEATHER. 241 



With such Skies, I have known cold South 

 Winds ; and on other occasions, with different 

 kinds of clouds, hot Northerly Winds in spring. 

 The peculiar appearances which attend these 

 exceptions to the usual coincidence of phae- 

 nomena ought to be particularly attended to. 



I have slightly mentioned these circumstances, 

 from a belief, that in general the particular 

 order and arrangements of the clouds are not 

 sufficiently attended to. It is to be hoped, in 

 future, that more attention will be paid to this 

 part of the subject.* 



* There are many minute differences in the appearance of 

 the clouds, under different circumstances, which I have not 

 described, as every meteorologist must have observed them 

 for himself. Sometimes there is a wavy appearance of the 

 under part of a cumulostratus passing over, which looks like 

 the white foaming billows of the Ocean. This is generally a 

 symptom of variable weather, as is also the curling inward of 

 the fleecy protuberances of the cumuli, as they pass along in 

 the Wind. 



I have often thought it worth while to examine whether 

 the clouds did not present a different appearance, according 

 to the quarter from which the Wind blew, independent of 

 any other circumstance. The most varied and multiform 

 Curlclouds are certainly to be seen spread aloft in a calm 

 region, while Eurus is breathing his bitter and unwholesome 

 blast below; and the most regularly formed Stackenclouds 

 are those which art 1 wafted along by the Zephyr's musky
