    • • • lin'd with different fubftances, and in that ftate producing no fenfible effeT upon the thermome- t-er : this lie calls abfolute heat. He next aliens, that the capacity for contain¬ ing abfolute heat in any body, is diminiflied by the acquifition of Phlogifton, and vice verfa. , i > . i He therefore explains the produ&ion ot animal heat in this manner : The atmofpheric aii con¬ tains a great quantity ot abfolute heat, but when it is expofed to the blood in the lungs, which blood contains a quantity of phlogifton, the air having a ftrongcr affinity attrafts the phlogifton, bv which union its capacity tor containing abfo- lute heat is diminiflied, and a quantity ot that abfolute heat is depofited, proportionate to the quantity ot phlogifton imbib d. How it tms heat became fenfible, the blood in the left auricle ot the heart, would be much hotter than that in the rierht; but it is not fo : therelore, this abfolute heat, depofited by the air now phlogifticated, mult be abforbed by the blood when it parts with phlo¬ gifton. It appears theretore, that the capacity or die air for abiolute heat, is diminiflied in propor¬ tion to the quantity of phlogifton acquired : and * n' > f 4,i !-• y
