The diminution of thermoregulatory sweating during cold-reception at the skin.

Lorentz gas as a typical distribution of velocities for more than a moment. We may take the initial momentary distribution of velocities as conforming to Lorentz, but a moment later, owing to the finite distribution of the condensing wall, the ions there will have a radial distribution of velocity with v V v not equal to zero. With v * V v not equal to zero at the points we cannot make the gas a Lorenzian throughout a region by any uniform transformation to uniformly moving axes. The Lorentz gas cannot be regarded as an example for any finite region, however well it may serve as an example for an infinite region. The immediate appearance of v V v in the gas requires us to use our a' which is much larger than the 7L of the Lorentz gas.
