[John James Rickard Macleod, Scottish biochemist who received a Nobel Prize for the discovery of insulin.] Autograph Letter Signed ('J. J. R. Macleod') to the physiologist Luigi Luciani, proposing to translate his festschrift with G. A. Barricelli.

1p, 4to. In fair condition, aged and creased. Folded twice. Headed by Macleod 'Physiological Laboratory' and addressed to 'Professor Luigi Luciani'. He begins by explaining that '[t]hrough Dr G. A. Barricelli [i.e. Giovanni Alfonso Barricelli (1873-1934)] of this city' he has received 'the most interesting collection of "researches on Physiology and allied Sciences" published in honour of your 25th year as Professor in Rome'. He thanks Luciani for the publication, which he will 'prize [...] as a most valuable addition' to his library, 'well worthy of the noble object for which it was compiled'. Barricelli has told Macleod that he intends 'to undertake the translation into English of [Luciani's] "Physiology of Man", and he has asked me whether I would collaborate with him, and incorporate in the translated edition the recent work with which I may be acquainted'. Macleod has agreed to, as long as there is no other translation, and Luciani agrees to Macleod's 'adding what I think necessary of the more recent work published since the Italian edition', and that Barricelli's translation of the first hundred pages 'proves satisfactory'. In pencil on the reverse is a translation into Italian of Macleod's three conditions, presumably in Luciani's autograph.
