Note 151 — Chapter XI · THE WRITING OF THE 'ORIGIN OF SPECIES.'

This passage was published as a footnote in a review of the Life and Letters of Charles Darwin which appeared in the Quarterly Review, Jan. 1888. In the new edition (1891) of Natural Selection and Tropical Nature (p. 20), Mr. Wallace has given the facts above narrated. There is a slight and quite unimportant discrepancy between the two accounts, viz. that in the narrative of 1891 Mr. Wallace speaks of the "cold fit" instead of the "hot fit" of his ague attack.
