The ancients were also of opinion that the brain is the coldest viscus in the animal frame, being in this respect the antagonist of the heart, the heat of which they supposed that it counteracts. See Aristot. (De Part. Anim. ii, 7); and Pliny (Hist. Nat. xi, 49.) There appears to be some foundation for this opinion, since, as is remarked by Haly Abbas, those parts of the body which are vascular, and contain much blood, are naturally hot; whereas such as contain little blood are comparatively cold. Of this latter class are the brain, nerves, and fat. (Theor. i.) The later Greek authorities, as, for example, Theophilus Protospatharius and Nemesius, adopt a division of the brain as regards its connexion with mind, to which Galen and his immediate followers appear to have been strangers. According to it, Fantasy is connected with the anterior part of the brain; Cogitation, or the _discursus mentis_, with the middle; and Memory with the posterior. See, in particular, Theophilus (p. 184, ed. Greenhill.) This hypothesis was received by all the Arabian writers on medicine. See, for example, Averrhoes (Collig. ii, 20.) It was evidently an approach to the arrangement adopted by the phrenologists of the present day, who maintain that intellect is seated in the anterior part of the brain; the moral feelings in the middle; and the animal appetites in the posterior. SECT. LXIV.—THE MARKS OF THE TEMPERAMENTS OF THE STOMACH. The marks of a preternatural dryness of the stomach are, that those affected with it are liable to thirst, but little drink satisfies them; and they feel heavy with much drink, as the superfluity occasions gurgling in the stomach, or floats upon it; of those of a more humid, that they are not addicted to thirst, and bear readily much liquids, and rejoice in humid food. A stomach preternaturally hot has a better digestion than appetite, particularly with regard to those things which are hard and difficult to digest; it delights in much food and drink; neither is it hurt by the moderate use of cold things. A preternaturally cold stomach has a good appetite but not a good digestion, in particular with regard to such things as are of difficult digestion, and are of a cold nature, which therefore are apt to turn acid in it. And it delights indeed in cold things, but is readily hurt by the immoderate use of them. The intemperaments proceeding from disease differ from the congenital in this, that they long for opposite things, and not always alike. If the stomach then digests properly, it is of a moderate temperament; and if it does not it is of a bad; but if its eructations are fetid, its heat is inordinate and inflammatory; but if acid, the contrary. And in those who digest properly things of difficult digestion, the heat of the stomach is inordinate, and weak in those who cannot digest those things, but digest fishes. It must also be observed, whether or not the symptom
