twelve points, the heights of which were deter- 

 mined by barometric measurements *. I have 

 often earnestly wished, that my levelling should 

 be repeated and rendered correct by some well 

 informed traveller, who may visit this country, 

 at once so picturesque and so interesting to the 

 natural philosopher. 



When in the season of the great heats we 

 breathe the burning atmosphere of La Guayra, 

 and turn our eyes toward the mountains, we 

 are strongly affected by the idea, that, at the 



* The following are the barometrical observations, and 

 their results. Maiquetia, 335*0 j therm. 25*6°. La Venta, 

 a large inn on the northern slope of La Cumbre, or the Cerro 

 de Avila, bar. 294*1 5 therm. 19'2°. El Guayavo, or the 

 little Venta de la Cumbre, 285*3 ; therm. 18'7 0 . Fort of 

 La Cuchilla, 381*5; therm. 18*8°. Venta chica de San- 

 chorquiz, 284*2 3 therm. 18*7°. Near the spring of San- 

 chorquiz (la Fuente), 286 4; therm. 18*6°. Last little 

 Venta, before arriving at the Cross of La Guayra, 284*1 5 

 therm. 18*8o. The Cross of La Guayra, 292*2 ; therm. 19*6°. 

 The Custom House of Caraccas, Aduana de la Pastora, 

 barom. 301*3 5 therm. 15*1°. Caraccas at the Trinidad, 

 barom. 303*7 ; therm. 15*2° (See my Obs. Ast.> Tom. i, p. 

 296 et 367). The results calculated are perhaps somewhat 

 too little. The barometrical heights have been reduced to 

 the same time, by an exact knowledge of the effect of the 

 small atmospheric tides. The absolute elevation of the 

 barometer at the level of the sea here indicates less than 

 the same instrument gave, when carefully rectified in the 

 point 0 of the scale. The differences only are the question 

 here.
