396 ON THE FORMATION OF CLOUDS. 



o^ {\\e greatest portion of the vacant space in which 

 no cloud appeared, to be on the east side of the 

 Lune, whilst a strong easterly breeze was blowing 

 the supposed warm column of air, in the opposite 

 direction. And in the case of the insulated cloud, 

 which kept its stationary position for some hours, 

 with a bright sky on every side, and the land wes- 

 terly as high as at Biggins, the idea of radiation 

 will not apply in any way. 



If no satisfactory explanation has hitherto been 

 given for phenomena of this class, the question will 

 be an interesting one ; and I should like to hear 

 the opinions which such a problem might elicit 

 from our Manchester Meteorologists. 



I am, my dear Sir, 



Yours very truly, 



W. Sturgeon.
