A Monograph on the Sub-class Cirripedia (Volume 2 of 2)
Charles Darwin
Darwin's barnacle work continues into the sessile species, the familiar acorn barnacles of every rocky shore. Volume two examines their structure and, remarkably, their strange sexual arrangements, foreshadowing ideas he would soon make famous. Meticulous science from a mind gathering its evidence. The second half of the study that shaped a revolution in biology.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
