Abstract

PROF. J. B. S. HALDANE in his new book entitled “The Causes of Evolution”, p. 89, quotes the late Prof. Weldon as his authority for the statement that when the breakwater was built across the mouth of Plymouth Harbour, “the water inside became muddier, and the shore-crabs developed roomier gill-chambers”. This is a complete mistake—in fact, a double mistake. Prof. Weldon did not assert that the branchial cavities of the shore-crabs had become larger, and what he did assert was shown by myself at the time to be incorrect. The subject is discussed in detail in my “Modern Biology” (1928), pp. 189–199.
