Apparatus for determination of the penetration of particulate airborne material through the nose is described. The penetration of aerosols of liquid particles produced by a spray has been measured in rats, rabbits, goats, sheep and men. The penetration decreased with increase in the rate of flow through the nose.

Particles of the order of I μ diameter penetrate the nose at all rates of flow, while very few particles larger than 15 μ can penetrate except at low rates of flow.
