Attraction on Clouds and Vapours, 61 



On the 16th, I was in sight of Madeira, and crossed the 

 tropic of Cancer on the £4th, in longitude 24° 30' west 

 of Greenwich; the ship's course being S. S.W. The for- 

 mer part is consequently on the verge of the trades ; as the 

 latter is of the torrid zone. At this season of the year 

 the winds are variable, but generally strong.

Ilavannah is situated but a few miles south of the tropic 

 of Cancer, and^the land about it moderately high. It is 

 sheltered by the hills of the Cavannah from all winds be- 

 tween N.E. and E.S.E., and these are by far the most 

 prevalent. In the evening, however, it often shifts to the 

 north, or even a point or two to the westward. At this 

 season of the year the weather is intensely hot, with f re* 

 quent and violent storms of rain and thunder, which usually 

 take place between the houis of two and six in the after- 

 noon.
