Copy letter from Michael Foster, to M [Louis] Pasteur, Academie des Sciences, Paris Expresses the hopes of the President and Council of the Royal Society that Pasteur may be willing to deliver this year's Croonian Lecture. Foster explains that the subject of the lecture is of a physiological nature or otherwise connected to the problems of living beings, but that the exact topic and time can be decided by Pasteur; though on the latter point, between Easter and mid June is preferred. The honorarium is given as being 45 and 50 pounds, exclusive of the expenses associated with the lecture. 19 January 1889
