19154-5 carbon form, with 50539-5 oxygen, carbonic acid. 

 2672'7 hydrogen do. 21415-8 do. water.

 Deduct oxygen present"!

Remain ... 64103-3 grains of oxygen, required 

 for the complete combustion of 4*8 Ibs. of dry blood. 



It is assumed, in this calculation, that 24 Ibs. of blood 

 yield 4-8 Ibs. (20 per cent.) of dry residue. The re- 

 mainder, 80 per cent., is water.
