We bring attention to the fact that Maxwell's mean free path for a dilute hard-sphere gas in thermal equilibrium, (√(2)σ n)^-1, which is ordinarily obtained by multiplying the average speed by the average time between collisions, is also the statistical mean of the distribution of free path lengths in such a gas.
