[chap. i. that it seemed probable that this gradual deposition of a line uniform organic sediment was almost universal. Then the question arose whether the animals which secreted these shells lived at the bottom, or whether they floated in myriads on the surface and in the upper zones of the sea, their empty shells falling after death through the water in an incessant shower. Specimens of the soundings were sent to the eminent. Fig. 2.— bulloides, D'Orbigny. Highly magnified. microscopists Professor Ehrenberg of Berlin and the late Professor Baily of West Point.
