shade, absorbs so much heat, that, notwithstand- 

 ing- the nocturnal radiation toward a sky without 

 clouds, the earth and air have not time to cool 

 very sensibly from midnight to sunrise. At 

 Calabozo % the heat of the day, in the month of 

 March, was from 31° to 32*5° ; of the night, 

 from 28° to 29°. The mean of this month, 

 which is not the hottest in the year, appeared to 

 be nearly 30*6° ; which denotes an enormous 

 heat for a country situate within the tropics, 

 where the days are almost constantly of the 

 same duration as the nights. The mean tern- 



* At Calabozo, in the shade, and very far from the ground, 

 or walls, on the 15th of March 1800, at l h Reaumur's therm, 

 was 24*2° ; the whale-bone hyg., 86° : at seven in the evening, 

 th. 25°; hyg. 35-2°: at 12 h th. 23*2° ; h. 35-4°. The 16th of 

 March, at 17\ th. 22-7°; h. 36° : at 23\ th. 24-2°; h. 37° i 

 at0\ th. 23 8°; h. 35* : at 2 h , th. 26°; h. 34-3° : at 4j\ 

 th. 25-5° ; h. 33'5°: at T , th. 24-6°; h. 33 5°. The 17th of 

 March, at 16 h , th. 26 3° ; h. 34* : at 12" , th. 22 4° ; h. 35-3*. 

 The 18th of March, at 23 h , th. 23-2°; h. 36°: till 11\ at 

 night, not a variation of 05° in the two instruments. I think 

 that the climate of Calabozo is still hotter than that of Cu- 

 mana. Having engaged Mr. Rubio, to make observations in 

 this port during my absence, I am enabled to compare the 

 same days. At Cum an a Reaumur's therm, kept from the 

 15th to the 18th of March, from 7 h in the morning to 11 in 

 the evening, between 20° and 24°. At Calabozo/130 leagues 

 distant from the eastern coasts, at the same hours, it was 

 from 23* to 26°. At Cumana, the temperature of the month 

 of March, 1800, was 22 2° ; at Calabozo, nearly 245»
