434 METEOROLOGICAL OBSERVATIONS. 



FROZEN SLEET. 



January 2oth. Mr. H.'s man says that he caught this d?yin a 

 lane near Hackwood park, many rooks, which, attempting to fly, 

 fell from the trees with their wings frozen together by the sleet, 

 that froze as it fell. There were, he affirms, many dozen so dis- 

 abled. WHITE. 



MIST, CALLED LONDON SMOKE. 



This is a blue mist which has somewhat the smell of coal smoke, 

 and as it always comes to us with a N.E. wind, is supposed to 

 come from London. It has a strong smell, and is supposed to 

 occasion blights. When such mists appear they are usually fol- 

 lowed by dry weather. WHITE. 



REFLECTION OF FOG. 



When people walk in a deep white fog by night with a lanthorn, 

 if they will turn their backs to the light, they will see their shades 

 impressed on the fog in rude gigantic proportions. This pheno- 

 menon seems not to have been attended to, but implies the great 

 density of the meteor at that juncture. WHITE. 



HONEY DEW. 



June 4th, 1783. Fast honey dews this week. The reason of these 

 seem to be, that in hot days the effluvia of flowers are drawn up 

 by a brisk evaporation, and then in the night fall down with the 

 dews with which they are entangled. 



This clammy substance is very grateful to bees, who gather it 

 with great assiduity, but it is injurious to the trees on which it 

 happens to fall, by stopping the pores of the leaves. The greatest 

 quantity falls in still close weather; because winds disperse it, and 

 copious dews dilute it, and prevent its ill effects. It falls mostly 

 in hazy warm weather. WHITE.
