Reading edition

Mr. Lockwood believes (as quoted in ‘Quart. Journal of Science,’ April, 1868, p. 269), from what he has observed of the development of Hippocampus, that the walls of the abdominal pouch of the male in some way afford nourishment. On male fishes hatching the ova in their mouths, see a very interesting paper by Prof. Wyman, in ‘Proc. Boston Soc. of Nat. Hist.’ Sept. 15, 1857; also Prof. Turner, in ‘Journal of Anat. and Phys.’ Nov. 1, 1866, p. 78. Dr. Günther has likewise described similar cases.
