Mr. Walker, in various places of his work, calls the _cerebel_ or cerebellum, "the organ of volition," and, at page 145, he attributes ideas, emotions, and passions, to the cerebrum, though he states that acts of the will result from these. Now, if there is any truth established, it is that the _will_ is the result of the simultaneous action of the higher intellectual powers, and supposes attention, reflection, comparison, and judgment, mental operations, which Mr. Walker himself attributes to the cerebrum. Gall has made it very evident, that the _will_ is not the impulse that results from the activity of a single organ, but the concurrent action of many of the higher intellectual faculties--motives must be weighed, compared, and judged, before there can be any will, or determination of mind. The decision resulting from this determination, is called will. We consider it then proved, that there is no particular organ of the will. "Every fundamental faculty," says Dr. Gall, "accompanied by a clear notion of its existence, and by reflection, is intellect or intelligence. Each individual intelligence, therefore, has its proper organ; but reason supposes the concerted action of the higher faculties. It is the judgment pronounced by the higher intellectual faculties. A single one of these, however, could not constitute reason, which is the compliment, the result of the simultaneous action of all the intellectual faculties. It is _reason_ that distinguishes man from the brute; _intellect_ they have in common to a certain degree. There are many intelligent men, but few reasoning ones. Nature produces an intelligent man; a happy organization, cultivated by experience and reflection, forms the reasoning man." Nearly all physiologists deserving of the name, are now united in the opinion that the cerebellum is the organ of amativeness, as well as concerned in the regulation of voluntary motion. "It is impossible," says Dr. Spurzheim, "to unite a greater number of proofs in demonstration of any natural truth than may be presented to determine the function of the cerebellum."--"Mr. Scott," says George Combe, "in an excellent essay on the influence of amativeness on the higher sentiments and intellect, observes that it has been regarded by some individuals, as almost synonymous with pollution; and the notion has been entertained, that it cannot be even approached without defilement. This mistake has originated from attention being directed too exclusively to the abuses of the propensity. Like everything that forms part of the system of nature, it bears the stamp of wisdom and excellence in itself, although liable to abuse. It exerts a quiet but effectual influence in the general intercourse between the sexes, giving rise in each to a sort of kindly interest in all concerns the other. This disposition to mutual kindness between the sexes, does not arise from benevolence or adhesiveness, or any
