Note 13 — ADAM SEDGWICK, M.A., (continued 2)

Götte, at the end of a paper on The Development of the Layers in the Chick (Archiv. für Micr. Anat., Vol. X. 1873, p. 196), mentions that the so-called cells in Osseous fishes which Oellacher states to have migrated into the yolk, and which are clearly the same as those mentioned by Owsjannikow, are really not cells, but large nuclei. If this statement is correct the phenomena in Osseous fishes are precisely the same as those I have described in the Dog-fish.
