Page 566 - simple " forms of Orbitolites, and from the " simple " to the " complex " forms of the last-named type. And as all these earlier forms still flourish under conditions which (so far as can be ascertained) are precisely the same, there is no ground to believe that any one of them is better fitted to survive than another.

Page 554 - Let me, first, express my belief that, if we are ever to escape from the obscurities and uncertainties of our art, it must be through the study of those highest laws of our science, which are expressed in the simplest terms in the lives of the lowest orders of creation. It was in the search after the mysteries — that is, after the unknown highest laws — of generation, that the first glance was gained of the largest truth in physiology ; the truth of the development of ova through partiion and...
Page 549 - Cornuspira its shell forming a continuous spiral tube, with slight interruptions at the points at which its successive extensions commence ; while its sarcodic body consists of a continuous coil with slight constrictions at intervals. The second stage consists in the opening out of its spire, and the division of its cavity at regular intervals by transverse septa, traversed by separate pores, exactly as in Peneroplis. The third stage is marked by the subdivision of the " peneropline " chambers into...
