The author was led to his conception of a working unit by the energy quantum theory of Planck. So he takes the cell, together with its interaction with its physical and chemical environment as a physiocellular or functional or biologic working unit. The relationship of this biologic working unit (B) to its two determining factors, the cell or rather its minute morphologic structure (m) and the stimulating physical agent (including chemical), is expressed in an equation B = axm. In contrast to the quantum, which is a constant, all the members of the equation are variable. It is hardly likely that such a conception will find much favor. The fine composition of the cell
