These remarkable hyper-metamorphoses remind us of the metamorphosis of the embryo of Echinoderms into the Pluteus-and Bipinnaria-forms of the starfish, sea urchins and Holothurians; of the Actinotrocha-form larva of the Sipunculoid worms; of the Tornaria into Balanoglossus, the worm; of the Cercaria-form larva of Distoma; of the Pilidium-form larva of Nemertes; and the larval forms of the leeches; as well as the mite Pentastomum, and certain other aberrant mites, such as Myobia.

Jessop records a remarkable case of multiple aneurysm. This case was particularly interesting as it was accompanied by a postmortem examination. Pye-Smith reports an extremely interesting case in which death occurred from traumatic aneurysm of an aberrant subclavian artery. The patient fell from a height of 28 feet, lost consciousness for a few minutes, but soon recovered it.

Even in France, where they had many converts and were frequently in eruption, there was far more hospitality in the Germany of Bismarck's day, the Socialists, after a brief and aberrant attempt to suppress them, were allowed to run free, despite the fact that their doctrine was quite as abhorrent to German official doctrine as anarchism was to American official doctrine.

The sloth, indeed, is specially adapted in organization to an arboreal residence, but this change is individual, not tribal, this animal being an aberrant form of the ground-dwelling edentata. In the apes and lemurs, on the contrary, the ground-dwellers are the aberrant forms, stray wanderers from the host.

A wild and fleeting wish that civilisation were nearer, wherein to hide himself, struggled with a goading appreciation of the comforts in Torrance's shack; for Werner often of late was oppressed with the futility of his present sphere as malcontent. His aberrant reflections were interrupted by Torrance's rising impatience. "Here, Werner, what is it? Speak up!"

G. Mivart remarks, "is one of the most peculiar and aberrant forms to be found in the Order." 'Transactions, Zoolog. But it appears from M. Gaudry's wonderful discoveries in Attica, that during the Miocene period a form existed there, which connected Semnopithecus and Macacus; and this probably illustrates the manner in which the other and higher groups were once blended together.

We can, I think, account for this fact only by looking at aberrant forms as failing groups conquered by more successful competitors, with a few members preserved by some unusual coincidence of favourable circumstances. Mr.

The skeleton is of comparatively low stature, and is deemed to show close affinities to the type of the modern Eskimo. Without being unduly sceptical, one may once more wonder if the Crô-Magnon stock may not have produced this somewhat aberrant form. Even on such a theory, however and it is hardly orthodox diversity of physical structure would seem to be on the increase.

And we have evidence of aberrant groups having suffered severely from extinction, for they are almost always represented by extremely few species; and such species as do occur are generally very distinct from each other, which again implies extinction.

We can, I think, account for this fact only by looking at aberrant groups as forms which have been conquered by more successful competitors, with a few members still preserved under unusually favourable conditions. Mr.
