If the promised pub lication has not yet appeared, I should like myself to prepare such an one, with the addition of some unpublished writings by Galileo, Valarianus Magnus, and Pascal, along with my observations on the universal part of the Principles of Descartes. I simply want a large number of free copies. " Among the copies made by Leibnitz, there were besides notes on the " Principles," physical, physiological, and anatomical observations, mathematical writings, and especially passages from that notable diary which Leibnitz called, "Cartesii cogitationes privates. " They were not published. They passed from Leibnitz s librarjr to that of Hannover. prev next |
