From respiratio originates animal heat; sor it is ollanown that the rapid conversion os oxygen an carbo into carboni ac id gas, is always attende by an extricationi heat in the livinianimal, when in a healthystate; and this animal heat, at iis fource, is prevente from einthuris ut, b reason of the halitus o vapou whicli alWay accompanies the processos respiration. For it is,eli nown that the more frequently we respire, the more rapidiswe shali generate animal heat whilst the vapou keeps pace in quantity with the increased rapidit os respiration.
