If we assume that there may be distinct portions of the brain, organs of comparison, individuality, causality, &c., we naturally regard _them_ as the source of that combined faculty which we denominate _judgment_. We might argue, that if these organs were _permanently_ deficient, fatuity, or, at least, extreme folly, would be the result. By parity of reasoning we might infer, that if the function of such organs were _for a time suspended_, imagination, having lost its mentor, would, as it were, run wild, and an extravagant dream, granting an excitement, would be the result. If the organ of colour be excited, and form be asleep, we may have an _eccentric drawing_. If language and imagination are both awake, a poem or romance; so it _may_ chance, that if _all_ the proper organs are awake, there may be a rational dream. I yield not to the too finely-spun hypotheses of Gall, and his first whimsical topography of the cranium; the incipient idea of which, by the by, he owes to the Arabian phrenologists who, even in the olden time, had glimpses, although they decided on a different location. Imagination was in the _frontal_ region, reason in the _medial_, and memory in the _occipital_. In Dr. Spurzheim’s beautiful demonstration of the brain, he exhibits it almost as one large convoluted web. While the ultra-phrenologist is unravelling these convolutions, it is strange that he sees not the inconsistency of his cranial divisions. Some of the boundary lines of his organs _must be drawn across_ these convolutions. It will ever be impossible to decide the exact course of these, but the lines should be drawn in the direction of their fibres; for if the faculty be seated in one convolution, that faculty would proceed _in the course_ of its fibres, and not across the fissure from one lobule to another. Now the most frequent coincidence of the possession of great mental power, with full development of the frontal region of the skull, will naturally lead us to believe that it may depend on _causation_. Indeed a skull, as well as expression, may be phrenologically _changed_ by culture or thought. The skull of William Godwin, in early life, indicated an _intellectual_ development; then it became _sensual_, the _occipital_ organs being in excess; and again, as his mind was subject to more moral culture, the intellectual or _frontal_ again prevailed. I am informed, also, by Miss A——, that there was observed a progressive development of the intellectual region in the head of her father, an acute and deep thinker.
