MR. CHANTEY'S EXPERIMENTS. 359 



Our distinguished countryman, Mr. Chantry, has very 

 recently exposed himself to a temperature still higher 

 than any which we have mentioned. The furnace which 

 he employs for drying his moulds is about 14 feet long, 

 12 feet high, and 12 feet broad. When it is raised to its 

 highest temperature, with the doors closed, the thermo- 

 meter stands at 350, and the iron floor is red hot. The 

 workmen often enter it at a temperature of 340, walking 

 over the iron floor with wooden clogs, which are of course 

 charred on the surface. On one occasion Mr. Chantry, 

 accompanied by five or six of his friends, entered the 

 furnace, and, after remaining two minutes, they brought 

 out a thermometer which stood at 320. Some of the 

 party experienced sharp pains in the tips of their ears, 

 and in the septum of the nose, while others felt a pain 

 in their eyes.
