Bacteriologists are not in a position to disregard the limitations recognised by the physiologists. Precise data which are not available from experiments are far from sufficient to explain the properties of living matter; they must be supplemented by vaguer conceptions about the functions of a cell, its internal organisation and its susceptibility to stimulative or inhibitory agencies—conceptions which cannot yet be translated into recognised chemical substances and physical properties. One must therefore start by recognising that bacterial virulence, being dependent on vital processes, cannot be fully explained in chemico-physical terms.
