Suggestions are made for the measurement of evolutionary rates of metrical characters. The unit of time may be the year or the generation. The unit for the character may be a unit increase in the natural logarithm of a variate, or alternatively one standard deviation of the character in a population at a given horizon. Examples are given from mammalian paleontology of the calculation of such rates.
