359 Of a Spaniard who can endure the greatest Heat, 



and 25 inches in breadth was brought to a cherry red heat 

 at one of it:s extremities, and placed on bricks. The Spaniard 

 placed the sole of one of his feet on the red part : a portion 

 of the oil which still adhered to it immediately inflamed. 

 He applied the sole of the other foot in the like manner, 

 and this he repeated several times. 



Exp. III. The flat part of a large iron spatula 18 inches 

 in length was brought to a cherry red heat. The Spaniard 

 thrust out his tongue, applied it to the red part of the spa- 

 tula, and repeated the same thing several times. Three 

 glasses of pure water were then brought, into one of which 

 a few drops of sulphuric acid were put, and into another a 

 pretty large quantity of marine salt : the third contained 

 only water. The Spaniard was made to drink these three 

 glassfulls, and was able to distinguish perfectly the savour 

 of them. 



Exp. IV. He took a lighted candle, and drew the flame 

 of it several times over the posterior part of his leg from the 

 heel to the ham. He was examined after these trials, and 

 no part of his skin appeared to be in the least altered. The 

 sole of his foot seemed to be smokey — which ought to be 

 ascribed to the carbon of the oil — but his pulse beat from 1 30 

 to 140 times in a minute. It appears that since that time 

 he placed himself in an oven heated to 70 degrees, and re~ 

 inained in it some minutes. 



Dr. Blagden, a fellow of the Royal Society of London, 

 supported a still greater degree of heat. He heated an 

 apartment till Fahrenheit's thermometer rose to 260 degrees, 

 entered it with his clothes on, and remained in it 8 m.inutes. 

 At last he was much oppressed. Several other persons en-, 

 tered it also. His pulse when he quitted the apartment 

 li^at 144 times in a minute. 



In another experiment he entered, undressed, into the 

 same apartment heated to 220 degrees of Fahrenheit, and 

 remained in it 12 minutes without being inconmioded. 

 . In a third experiment, the chamber being heated to 250 

 degrees of Fahrenheit, he entered it along with several other 

 persons, and remained in it several minutes witiiout being 

 mcommoded. 



Some eggs and a beefsteak were placed in the same apart^ 

 jnent on a pewter dish; in twenty minutes the eggs were 

 entirely hard, and in forty-seven the beefsteak was not only 

 bajcod but almost dry.
