<p style='text-align: justify;'>The word 'demon' is not used by Maxwell. It first appeared in William Thomson's, 'The kinetic theory of the dissipation of energy', Nature, 9 (1874): 441-4. The book on Quaternions referred to on the last page is 'An Elementary Treatise on Quaternions' by P.G. Tait (Oxford 1867). For more details see: P.M. Harman, 'The scientific letters and papers of James Clerk Maxwell', Vol.II, CUP 1995, pp.331-333. This photograph of the manuscript was probably taken on the occasion of the Maxwell Centenary Celebration in 1931.</p>
