XL VII. Further Experiments and Obfervatmis in an 
heated-Room, By Charles Blagden, M. D. F,R. S, 
Redcle, July 6, tlic third of April, nearly the famepar- 
775 ty as before r-’;, together with Lord SEA- 
FORTH, Sir GEORGE HOME, Mr. DUNDAS, and Dr. NOOTH, 
went to the heated room in which the experiments of the 
23d of January were made. Dr. fordyce had ordered 
the fire to be lighted the preceding day, and kept np all 
night; fo that every thing contained in the room, and 
the walls themfelves, being already well warmed, we 
were able to pufli the heat to a much higher degree than 
before. In the courfe of the day feveral different fets of 
experiments were going on together; but to avoid confu- 
fion, it will be necelfary to relate each feries by itfelf, with- 
out regard to the order of time; beginningwiththatferies 
which ferves as a continuation of our former experiments . 
Soon after our arrival, a thermometer in the room 
rofe above the boiling point ; this heat we all bore per- 
fedlly well, and without any fenfible alteration in the 
temperature of our bodies. Many repeated trials, in fuc- 
ceflively higher degrees of heat, gave ftill more remarka- 
ble proofs of our refilling power. The lafl of thefe expe-
