304 METEOROLOGICAL OBSERVATIONS. 



FROZEN SLEET. 



JANUARY 20. Mr. H.'s man says that he caught this day, in 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 

 disabled. 



MIST, CALLED LONDON FOG. 



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 

 followed by dry weather. 



REFLECTION OF FOG. 



WHEN people walk in a deep white fog by night with a lan- 

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

 their shades impressed on the fog in rude gigantic proportions. 

 This phenomenon seems not to have been attended to, but 

 implies the great density of the meteor at that juncture. 



HONEY DEW. 



JUNE 4, 1783. Vast 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 dis- 

 perse it, and copious dews dilute it, and prevent its ill. effects. 

 It falls mostly in hazy warm weather.* 



MORNING CLOUDS. 



AFTER a bright night and vast dew, the sky usually becomes 

 cloudy by eleven or twelve o'clock in the forenoon, and clear
