Excerpt from Observations on the Gemmule and Egg Development of Marine Sponges, Vol. 9 The observations described in the present paper were begun more than four years ago, when as Bruce Fellow of the Johns Hopkins University I was permitted by the directors of the fellowship to spend a considerable part of the academic year in the Bahama islands.
