108 FROM TENERIFFE TO BRAZIL. 



and head ache ; the air was extremely sultry ; and 

 our thermometer was never below 20° Reaum. 

 These sicknesses soon yielded to the skill of our 

 surgeon, without leaving any bad consequences, 

 and were entirely over when we had got to some 

 distance from the Cape Verd islands. At noon 

 we passed the latitude of the island of St. Antonio, 

 at the distance of thirty-five miles, without seeing 

 it. During the night twenty-five flying-fish fell 

 on our deck, which appeared on our table at din-

 These fish frequently fall into small ships, which, 

 like our Rurick, do not rise higher above the

 enemy j sometimes they strike with violence against 

 the ship's sides, and then fall stunned into the 

 water. As I had not seen the island of St. An- 

 tonio, I directed my course so as to come in sight 

 of Brava, the southernmost of the Cape Verd 

 islands, to try the going of my chronometers. A 

 fresh trade wind carried us rapidly forward. 



At ten o'clock, at noon, we discerned the island 

 of Brava, rising above misty clouds, at the dis-

 the longitude of this island, 10' more to the east 

 than marked in Horsburg's chart ; and I have rea- 

 son to believe my statement to be the more 

 correct, because numerous astronomical observ- 

 ations, which were made before and after we saw 

 this island, always gave the same longitude as the
