Abstract
ABSTRACT During my stay at Villafranca, in August and September, 1874, I had occasion to make some observations on the development of an osseous fish. I applied myself chiefly to the study of the segmentation and endeavoured to elucidate the much discussed question of the origin and mode of formation of the embryonic layers. I found daily, in the midst of the produce of my fishing with Müller’s net small pearl-like bodies, colourless and perfectly transparent, floating freely near the surface of the water; the diameter of these little hyaline spheres scarcely exceeded that of a large Noctiluca, and it was only after I had examined them with a lens that I discovered that I had before me the embryos of an osseous fish.
