The thermometer, (division of 

 Reaumur) is reduced to that of the cel- 

 lars of the observatory at Paris,which, 

 according to researches made after 

 my return to Europe, was found 

 0.37° cent, too high. The hygro- 

 meter was of whalebone. These in- 

 dications are not corrected by the 

 temperature. On the night of the 

 17th of August, when the thermome- 

 ter sank rapidly to 18", at the same 

 instant (by the cooling of the upper 

 layers of the air) a fine halo was 

 formed around the moon. On the 

 25th of August, during a furious 

 north-east wind, the thermometer 

 sank at 9 h in the evening to 17. 5° R. 

 This was the beginning of the small 

 rains which form what the people of 

 Cumana call the winter season. 



Days considered as excessively- 

 hot at Cumana, 1799, and 1800, 

 27 Aug. at noon 24.0° Reaumur. \

 When the thermometer at Cuma- 

 na, has been at 23°-25° (hygr. 48° 

 Deluc) , during three days, we expe- 

 rience a feeling of cold when the 

 thermometer descends after a storm 

 of rain, to 18o— 19o R. (hygrometer 

 62o Deluc) . See above, Vol. ii. p. 

 252.
