In considering the experiments of Buccich (6) on propagation of sponges by cuttings, two main questions present themselves:—
(1) If a sponge be divided into many fragments, will the total increase of such fragments and their progeny be greater than the increase of the intact sponge and its progeny would have been in the same time; the conditions of water, &c., being identical?
(2) Are sponges, grown as recommended by Buccich, more or less favourably situated than those on the sea-bottom?
