1. Squalls of Wind on the African Shores. — It is well known 

 that on the African shore violent squalls of wind and rain are 

 very often met with by ships on the coast. They are almost 

 always accompanied by the most vivid electrical phenomena ; 

 and though perhaps less dangerous in their effects than the 

 thunder storms which occur in colder climates, exhibit appear- 

 ances vastly more magnificent. The following particulars I 

 have heard my father relate frequently concerning these squalls ; 

 and their connection with some of the recent discoveries in elec- 

 tricity will at once be perceived. The approach of the squall is 

 generally foreboded by the appearance of jet black clouds over 

 the land, moving in a direction towards the sea, at the same lime 

 that a gentle breeze blows towards the shore. In these circum- 

 stances, the precautions which my father usually adopted, was 

 to take in immediately all sail, so as to leave the ship under bare 

 poles, and send the whole of the crew below decks. As the 

 tornado approaches nearer, the rain is observed to be gushing 

 down in torrents, and the lightning darting down from the 

 clouds with such profusion as to resemble continued showers of 

 electric matter. When, however, the squall comes within the 

 distance of about half-a-mile from the ship, these electric appear- 

 ances altogether cease ; the rain only continues in the same man- 

 ner. As the tornado is passing over the ship, a loud crackling 

 noise is distinctly heard among the rigging, occasioned by the 

 electric matter streaming down the masts, whose points serve
