. The cat : an introduction to the study of backboned animals, especially mammals. Cats; Anatomy, Comparative. 378 THE CAT [chap, xi.; All such animals however, as those just mentioned, have a well developed nervous system; but there are other animals in which symmetry of form is carried to the highest degree, while yet no trace of a nervous system is to he detected in them. Such creatures are the Radiolarians—minute marine organisms of. Fig. 163.—DORATASPIS POLYANASTEA. ADULl almost the simplest structure as regards their soft substance, but which have siliceous skeletons of extreme complexity and beauty, and, at the same time, of marvellous symmetry. § 10. In such an animal as the cat, then, we have indeed evidence of a principle of individuation ; for in it we have not only symmetry of organization and harmonious organic action (as in the lowly organized creatures just referred to), but also sense perceptions, which meet in a central sensitive faculty able to discriminate the odorous from the coloured and the sapid from the audible. Not that there is any reason to think that the cat can appreciate the odours, &c, as such, but only that it is practically impressed by the relations and distinctions between its own sensations as well as between the objects which elicit them. It has, in fact, not con- sciousness but " CONSENTIENCE." § 11. But, as we have seen, its nervous system ministers to a vast number of actions which are unfelt as well as to its felt actions, while its life is also made up of actions which the nervous system.
