XII. Experiments and Obfervations in an heated Room. 
By Charles Blagden, M. D. F. R, S. 
vitation from Dr, geoPv.ge fordy ce, to obferve the effedts- 
of air heated to a much higher degree than it was for- 
merly thought any living creature could bear. We all 
rejoiced at the opportunity of being convinced, by our 
own experience, of the wonderful power with which the 
animal body is endued, of relifting an heat vallly greater 
than its own temperature ; and our curiolity was not a 
little excited to obferve the circumllances attending this 
remarkable power. We knew, indeed, that of late feve- 
ral convincing arguments had been adduced, and obfer- 
vations made, to hiew the error of the common opinions 
on this fubejdt; andthatDr. FORDYCEhad himfelf proved 
the miftake of Dr. BOERHAAVE^‘'^'and mofh other authors, 
by fupporting many times very high degrees of heat, in 
the courfe of a long train of important experiments ; 
with which, and his moll philofophical conclulions from 
them, every lover of fcience mull earneftly wifh that he 
may foon favour the public. In the mean time time, I 
am happy in an opportunity of laying before this So-
