Sinopsis
Excerpt from The Early Development of Planorbis: A Dissertation
The investigation, the results of which are recorded in the present paper, was carried on under the supervision of Prof. C. O. Whitman, at the University of Chicago and at the Marine Biological Laboratory at Woods Holl, Mass. It is a source of gratification to acknowledge the generous treatment I have received in both these places at Professor Whitman's hands. I wish also to express my appreciation of the many suggestions I have received from Dr. E. G. Conklin, both in person and through his admirable paper on the Embryology Of Crepidula.

Excerpt from The Early Development of Planorbis: A Dissertation
The eggs of Planorbis, when brought into contact with water, swell quite rapidly, so it is best to tease them out of the cap sules directly into fixing fluid. The eggs may, however, be teased first into normal salt Solution, to which it is better to add a small quantity of the fixative, and then treated with the fixing fluid alone. Some fixing fluids coagulate the albuminous substance around the egg so quickly, after or during its escape from the capsule, that it usually becomes surrounded with more or less coagulated albumen, from which it is difficult to free it. By teasing directly into normal salt solution, mixed with only a small quantity of the fixative, the eggs may be obtained free from any foreign material. Normal salt alone often causes more or less swelling.
