Page 176 - cover a wider ground, that the phases of development of all living animals correspond to the order of succession of their extinct representatives in past geological times. As far as this goes, the oldest representatives of every class may then be considered as embryonic types of their respective orders or families among the living.
Page 8 - Are they the devices of the human mind to classify and arrange our knowledge in such a manner as to bring it more readily within our grasp and facilitate further investigations, or have they been instituted by the Divine Intelligence as the categories of his mode of thinking
Page 178 - among the representatives of older periods, of nearly every class of animals, which, in the state of their perfect development, exemplify such prophetic relations, and afford, within the limits of the animal kingdom at least, the most unexpected evidence that the plan of the whole creation had been maturely considered long before it was executed.
Page 202 - unequal gifts. ,9th. The distribution of some types over the most extensive range of the surface of the globe, while others are limited to particular geographical areas, and the various combinations of these types into zoological provinces of unequal extent, exhibit thought, a close control over the distribution of the earth's surface among its inhabitants.
Page 78 - and it has laid the foundation for the conviction, now universal among well informed naturalists, that this globe has been in existence for innumerable ages, and that the length of time elapsed since it first became inhabited cannot be counted in years. Even the length of the period

There exists, besides, as much individuality, within their respective capabilities, among animals, as among men, as every sportsman, every keeper of menageries, and every farmer or shepherd can testify, or any one who has had large experience with wild, tamed or domesticated animals.
Page 97 - This argues strongly in favour of the existence in every animal of an immaterial principle similar to that which, by its excellence and superior endowments, places man so much above animals.
Page 8 - Have we, perhaps, thus far been only the unconscious interpreters of a Divine conception, in our attempts to expound nature ? and when in our pride of philosophy we thought that we were inventing systems of science, and classifying creation by the force of our own reason, have we followed only, and reproduced, in our imperfect expressions, the plan
Page 79 - the corals by which they were all built up are the same identical species in all of them. These facts, then, furnish evidence as direct as we can obtain in any branch of physical inquiry, that some, at least, of the species of animals now existing, have been in existence over thirty thousand years,
