most of the lightning rises in the west and extends towards 
the east. Numerous observations have been made on the ef- 
fects of lightning o]| trees of different kinds. Experienced

The Natural History Society of Halle proposes to publish 
a hail-chart of Germany, with the view of shewing its ex- 
tent, position, and magnitude during a series of years. It is 
also proposed to publish a series of maps representing the direc- 
tion lightning takes in different parts of the world, particu- 
larly in Europe.
