During the three years 1810-1812, when Senor 

 Ferrer took the mean altitudes, the extreme varia- 

 tion on those days when the mercury rose or fell 

 most in the barometer, did not exceed thirty milli- 

 metres. In order to exhibit the accidental oscilla- 

 tions of each month, I present here the table of 

 observations in 1801, in the hundredth parts of an 

 English inch, according to the manuscript notes of 

 Don Antonio Eobredo.

Hurricanes are less frequent in Cuba than in St. 

 Domingo, Jamaica, and the Lesser Antilles situate 

 east and south of Cape Cruz ; for we should not 

 confound the violent north winds with the hurricanes, 

 which most generally blow from the S.S.E, or the
