Natural history; Natural theology; Sciences naturelles; Théologie naturelle. 93 istence of an intellectual principle, spirit, or soul, whose links of connexion with the external world are the sensory ganglia and cerebral hemispheres. We may profitably enquire whether any arguments in behalf of the existence of such an agent may be gathered from anatomical and physiological facts, or whether we must assume it as a postulate, relying for proof on evidences of a totally different character to those which are presented by the science in ques- tion. It is to be greatly regretted that evidence drawn from structural arrangement has hitherto, by very high authority, either been totally cast aside, or held in very light esteem. It is still more deeply to be regretted that those who should have known better have conceded the argument, that from no consideration, based upon anatomical or structural arrangement, could proof be obtained of the ex- istence of an immaterial principle. But what if it should turn out that, from the study of the cerebral mechanism, distinct proof can be obtained on this point—proof of just as cogent a nature in support of the doctrine of the existence of the soul as that which we have of the existence of the external world, and of precisely the same character. We may present it as follows : The simple cellated nervous arc consists essentially of these portions, a centripetal fibre, a vesicle, and a centrifugal fibre : the centi ipetal fibre may have, at its outward or receiving extremity, vesecular or cellular mate- M.
