S K By Alexander Agassiz And C. O. Whitman. Read May lh, 1884. Considerable attention has in late years been paid to fish eggs / found floating on the surface, more especially since the establishment of various Fish Commissions to study the history of the sea-fishes. As early as 1868, Malm1 raised the eggs of a species of Flounder by v$t artificial fecundation, and found them to float on the surface at first, and in the later stages of development to sink gradually below the surface. Sars,2 in 1869, found that the eggs of the Cod floated on the surface. Haeckel,8 during a visit to Corsica, in 1874, also found pelagic fish eggs which he referred to some Gadoid: he subsequently found the same eggs at Nice, in 1876. E. van Beneden,4 in 1874, studied pelagic fish eggs at Villa Franca. Kupffer,6 in 1868, published some interesting investigations on pelagic fish eggs found in the harbor of Kiel. Mr. Ryder6 and Colonel McDonald of the United States Fish Commission observed that the eggs of the Spanish Mackerel were found floating on the surface. In 1879 and in 1882 A.
