In a recent note, D. A. Lloyd has obtained a formula for the frequency distribution of time dependent errors in terms of the exponential integral

This note clarifies Lloyd's derivations by referring to a theoretically identical, though conceptually different, time-independent, physical model, relates this distribution to one described by Anderson and concludes with a short appreciation of the role of the negative exponential distribution in navigational studies.
