It remains for us to fay a few words in refpeét to the cir- 
enfitances under which the great‘abitraction of eo heat 
may be unfafe: for although the abfurdity of the humoral 
dine s may be confpicuous, and the danger ‘of repelling 
the materics morbi from the furface to the internal parts may 
be gratuitous and vifionary in a great degree; yet there are 
varieties of dif e and: ftates o the contin = which

in’ febrile difeafes is only unfafe, when the heat | is not pre- 
ternaturally great ; when it is not fteady, but fluctuating, 
or alternating with chills’; when it is only partial ; when it 
is accompanie by general or profufe perfpiration ; "aad even 
when the heat, as meafured by the thermometer, is preter- 
naturally t, if the patient be acutely fenfible to impref- 
fions of cold on the furface, the application of cold will be 
unfalutary. Ina word, whenever the faculty of cooling
