My dear Darwin

Let me thank you for your note and for the great pleasure I have had in even a partial reading of your new book—though it makes me feel that we must go beyond plants for a really elemental pathology—¹ I wish I knew enough of crystals to work at them— I gladly take note of your promise to come to luncheon.² Any day will do and the sooner after 1 the better for the longer time—

Sincerely your’s | James Paget.
