To the right and left are dwarf colonies nine days old drawn to the same scale, from fragments of fertilized eggs, one of approximately one half, the other of one fourth the bulk of an entire egg. be seen that the dwarfs are very exactly similar to whole colonies of reduced proportions. Beyond this stage it was not found pos- sible to rear the young colonies, even after three weeks, probably owing to the difficulty of providing the animals with suitable food. These results are of some interest as proving that in this case the process of budding does not depend on the attainment of a certain size-limit by the parent stock, but on that of a definite ontogenetic stage, exactly as if the buds were organs of a single individual. It can hardly be doubted that in the ancestral type.
