Using a densimeter technique, the effect of tannic acid and n-butanol on the permeability to non-electrolytes of erythrocytes of various species was studied. If both tannic acid and butanol decrease the permeability it is suggested that a carrier mechanism is involved. If tannic acid has little or no effect and butanol increases the permeability it is suggested that the penetration of such a molecule depends only on diffusion. According to this theory carriers are involved in the following systems: Urea - mouse, sheep, pig, ox and man; Ethylene glycol - man and possibly mouse; Glycerol - man, mouse, rabbit; Erythritol - mouse and possibly man; Ribose - mouse, man; Mannose, glucose, sorbose - man. No carriors are involved in the following systems: Urea - chicken; Ethylene glycol - pig, chicken, ox, sheep; Thiourea - rabbit, chicken, sheep, man, pig, ox; Glycerol - chicken, pig, sheep, ox; Erythritol - rabbit; Ribose - rabbit.
