In later experiments, the eggs, freed from their outer mem branes, were placed on dry pieces of filter paper, six to eight on each small piece. The water adhering to the inner membranes made a small damp spot around each egg. The pieces of paper were then put into glasses with covers to prevent further drying. In the course of a few hours the eggs became flattened on the side in contact with the paper. The segmentation continued under these conditions, and. 6 FIGS. 1-6.

In the majority of cases, however, the egg died, or the development was retarded.
