Lichtenberg on hail. N. Hannov. Mag. Jan. 

 1793. Eixl. Naturl. 



Thinks, that hail depends on" electricity, perhaps as 

 promoting evaporation and cold. Observes, that it very sel- 

 dom hails at night ; that in wiiuer snow is much more 

 common than hail ; that it often snows or rams for some 

 days, and then hails with thunder ; and that hail often at- 

 tends volcanic explosions. Most of these circumstances 

 ire easily understood, if we consider that much of the cold 

 which congeals the hail is probably produced by evapora- 

 tion.
