On the evening^of the 5th, at 9:30, a very brilliant meteor fell in the west, 

 starting from*about the tail of Leo and moving vertically toward the horizon. It 

 was ten times the size of Jupiter and burned with a greenish-yellow light and 

 with a luminous train. 



There was a remarkable rainbow on the 15th, lasting from half an hour be-

 the ground of dark clouds from the retreating storm.
