Cambridge: Cambridge University Press, 1882-4. First Edition. An attractive presentation, presumably to a graduate of Lord Kelvin's important series of lectures on "Molecular Dynamics and the Wave Theory of Light," delivered at Johns Hopkins in 1884. Thomson always referred to this cohort as his "Baltimore Coefficients," and praised them on numerous occasions, most notably in the Preface to the Baltimore Lectures, in which he writes: "...I hope it will be satisfactory to all my Baltimore coefficients still alive in our world of science, when this volume reaches their hands; to find in it dynamical explanations of every one of the difficulties with which we were concerned from the first to the last of our twenty lectures of 1884..." Though we do not find clear evidence of an A.B. Nixon in attendance at Johns Hopkins at this period, we do find several mentions of a Nixon in the finding aids to Lord Kelvin's correspondence at the University of Glasgow, including reference to a testimonial for Nixon in a letter to his older brother James Thomson in 1878. Two octavo volumes (only, of an eventual six). Original olive green cloth, lettered in gilt on spines; pp.558,(2),31; three inserted leaves of plates (folding) + x,407,32; twenty inserted leaves of plates (some folding). Volume 1 with mounted presentation on Glasgow University stationery: "To [in separate hand]: A.B. Nixon / in remembrance of the Baltimore Coefficients of October 1884 / with Kind regards William Thomson," dated Dec.3, 1884. Publisher's catalog present at rear of each volume, both dated December 1884 (making volume 1 presumably a later printing, though not otherwise indicated). Volume 1 spine nicked at base, with general light external wear; rear hinge cracked, else clean, tight and unmarked; Volume 2 in somewhat fresher condition, with thin partial crack to front hinge (internal), light external soil; Very Good.
