I {hall not therefore dwell any longer on a fubjed which is fo much more eafily contro- verted than underftood, but proceeding to the Experiments themfelves endeavour to examine their accuracy, and from thence determine how far they may be depended upon as conclufivc in favor of any hypothefis. In almoft the whole of Dr. C’s Experiments water is employed as an ingredient. The ab- brium, I imagine fome bodies are better fitted by nature to be conductors of that fluid than others.—Thus, if a body which is a good conductor of fire readily receives it into its fubltance and conducts it through the whole to all the parts* as metals and waters do, and if two bodies both good con- ductors, one heated the other in its common flate, are brought into contaCt with each other, the body which has molt fire readily communicates it to that which had leaft, and that which had lead readily receives it till an equili- brium is produced.” Dr. Franklin’s Philofophical Works, p. 351.—5th Edit. folute](https://iiif.wellcomecollection.org/image/b21513958_0016.jp2/full/800%2C/0/default.jpg)
