    indirect effect of the ammonia solution. The latter induces the development in the unfertilized eggs, but if they are not treated with the hypertonic solution they will disintegrate. The case is similar to our experience with artificial mem- brane formation by weak acids. The eggs will die after this treatment if they do not receive the necessary second treat- ment. It is not the weak acid which kills the eggs in this case but the membrane formation without the addition of the second factor. If fertilized eggs receive the same treatment with a weak acid they will not suffer at all.
