I?49 ’ is fituate in 10 Degrees, 25 Min. 
481 Seconds of North Latitude. The Weather there 
is aiways fultry hot. A Thermometer conftruded 
by Monf. de Reaumur gave, on the 19th of Novem-

of the Warmth of the Air 1025 Divifions and a 
half; and this with little Variation, both Night and 
Day. The greateft Height to which the Spirit af- 
cended at Raris the fame Year, by a Thermometer 
graduated in the fame Manner, was 102 y and a half;
