at our disposal a negative of the fine portrait, which forms the frontispiece to Volume II. For the opportunity of making facsimiles of diagrams in certain of the letters, we are once more indebted to Sir Joseph Hooker, who has most generously given the original letters to Mr. Darwin's family.

OUTLINE OF CHARLES DARWIN'S LIFE.

BASED ON HIS DIARY, DATED AUGUST 1838.

References to the Journals in which Mr. Darwin's papers were published will be found in his "Life and Letters" III., Appendix II. We are greatly indebted to Mr. C.F. Cox, of New York, for calling our attention to mistakes in the Appendix, and we take this opportunity of correcting them.

Appendix II., List ii.—Mr. Romanes spoke on Mr. Darwin's essay on Instinct at a meeting of the Linnean Society, December 6th, 1883, and some account of it is given in "Nature" of the same date. But it was not published by the Linnean Society.

Appendix II., List iii.—"Origin of saliferous deposits. Salt lakes of Patagonia and La Plata" (1838). This is the heading of an extract from Darwin's
