Meteorological Observations. 159 



While supper was preparing, he perceived something falling on his 

 hat like drops of rain ; but as there were no clouds to be seen, pre- 

 sumed it could not be rain. On looking on the ground near the fire 

 he saw distinctly that the falling substance instead of being rain was 

 a small winged insect, which although unable to fly had yet life and 

 motion. Tlie number rapidly increased so as to give great annoy- 

 ance by falling into the frying-pan and supper vessels, and continued 

 until the ground was covered by the shower. On the following 

 morning Sir George ascertained that this extraordinary shower ex- 

 tended at least from twenty-five to thirty miles in the direction he 

 was travelling. No information has been received as to its extent 

 in other directions. It w^as observed that soon after the shower the 

 ■weather changed suddenly from warm to cold. It is therefore pro- 

 bable that the whole of this immense swarm of insects encountered 

 the cold current, and were paralyzed and precipitated thereby. 

 They all died soon after falling. Specimens of these insects were 

 collected by the attendants of Sir George, from whom I received 

 them. In no instance however were they seen to revive after coming 

 into a warmer atmosphere. — American Journal of Science and Arts
