There is, further, no evidence that the removal of the mechanically attached eggs from a lobster in June alters its physiological con- dition. Mr. Scott says further: "There was no obvious need to kill one lobster each month to discover whether it was going to extrude eggs or ; This would seem to be an obvious conclusion, but it should have been equally clear that this step was taken for another purpose, namely, to follow the changes which were taking place in the ovary itself. The con- dition of the ovary tells us at once whether growth of the ova is active or slow, or whether an absorption of the eggs already formed is going on. The step was far from need- less, for after July it proved that there was no preparation for the production of fall or winter eggs. In other words, it showed that in these animals there was no tend- ency to produce eggs in each of two consecutive years, the chief point in the experiment. It was impossible to foresee how many of these animals would die in the course of their confinement or because of it, but had all of them lived two-thirds of the total number at the start, or 24, would have had a chance to spawn in 13 months from the time the experiment ; a The experiment would h
