from the cessation of this inequahty, the superior atmo- 

 Fphere having become warmer, the interior colJer : attend- 

 ed with a decrease of the superficial evaporation. It be- 

 gins to form some hours after sun-rise, because the vapour 

 requires that space pf time to become elevated by the gra- 

 dual accession from below. When a stratus covers the 

 ground at sun-rise, however, we often see it collect into 

 cumuli upon the evaporation of that part of it which is im- 

 mcdiatelv contiguous to the earth : and this effect ought to 

 happen ; for the cloud is then insulated, the vapour plane is 

 established, and every thing in the same state, except in 

 point of elevation, as in the ordinary mode of production 

 of the cumulus. 



Lastlv, the cumulus, however dense it becomes, does not 

 afford rain, because it consists of drops similarhj electrified 

 and repelling each other, and is moreover contmually eva- 

 porating from the plane of its base. The change of form 

 which comes on before it falls in rain, and which indicates 

 a disturbance of its electrical state, will be noticed hereafter.

LXV. Account of a Spaniard who can endure, without 

 ieing incommoded, the greatest Degrees of Heat. Bi/' 

 J. C Delamethkuie*. 



A. NATIVE of Toledo, in Spain, about 23 years of age, 

 who arrived lately at Paris, has made different experi- 

 ments to show that he is capable of enduring the greatest 

 degrees of heat without being incommoded. We shall hfere 

 give an extract of those made at the school of medicine be- 

 fore several of the professors, about three hundred of *the- 

 pupils, and several other persons. 



Care was taken to examine him before, and it was found 

 tjiat his state exhibited nothing different from that of a man 

 in good health. His pulse beat about 75 or 78 times a 

 minute. 



Exp. I. A vessel containing oil heated to 85'^ of Rcau- 

 nuir being prepared, he opened his hand and apphed the 

 palm of Tt several times to the oil ; he then washed his 

 hands and face in the oil, and applied the soles ot his feet 

 to it. At the end of the experiment the heat of the oil was 

 5till from 7G to 78 degrees. 



Exi'. n. A bar of 'iron from 18 to 20 inches in length
