TO GUAHON. 22.5 



the least indication of land being near. I still 

 continued my course to the west, either to come 

 up to the island of Hogelon, or perhaps to make 

 some new discovery, as this part has not, to my 

 knowledge, been examined by any navigator. The 

 water had already, for some days past, become of 

 a blueish colour, and has since become a hun- 

 dredth part Salter than usual. During the night 

 we had violent rain, gusts of wind, and lightning. 

 . The nth: latitude 9" 19' 56"; longitude, ac- 

 cording to the chronometers, 201° ^5'. We were 

 now at the place on which Hogelon*s Island was 

 said to lie, but looked about for it in vain, and I 

 believe I may affirm that it does not exist. As 

 well on the 11th, as on the 12th, a number of dis- 

 tances were taken between the sun and moon ; the 

 longitude calculated from which, exactly agreed 

 with the longitude by the chronometers. 



The 13th, at noon, we were in latitude 8" 59' ; 

 longitude, according to the chronometers, 204 "* 

 24". The water is still uncommonly blue. I sup- 

 pose that the sea, from the Ralick chain to this 

 place, and perhaps still farther to the west, is of 

 less considerable depth than east of Radack. The 

 Six-thermometer, which I let down to-day, during 

 the calm, gave the temperature of the water in 

 the depth of the sea much colder than it is 

 on the other side of Radack, and in all other 

 parts under the tropics which lie in this latitude.
