โฆ Synopsis
With respect to their osmotic environment eggs fall naturally into two classes ; those which are essentially in osmotic equilibrium with the surrounding medium such as eggs of marine invertebrates, and those which show a considerable degree of independence of the osmotic environment, represented by amphibian, avian, reptilian, and teleost eggs. Possibly in this latter class fall also the eggs of fresh water invertebrates but practically no information is available for this group.

Values of k may easily be computed froin the volume-time curve by drawing a tangent to the curve at any desired instant; the details of this method are given elsewhere(5). But for purposes of greater accuracy the integrated equation has been used in the present paper.
I n a recent paper it was reported(1) that the fragility of certain mammalian erythrocytes is increased by testicular extract. In the last analysis such a change in erythrocytes signifies an increase in their permeability to hemoglobin. Since there was a certain amount of evidence from the work of D
