If the humour be cold, it is, saith [1071]Faventinus, a cause of dotage, and produceth milder symptoms: if hot, they are rash, raving mad, or inclining to it. If the brain be hot, the animal spirits are hot; much madness follows, with violent actions: if cold, fatuity and sottishness, [1072]Capivaccius. [1073]The colour of this mixture varies likewise according to the mixture, be it hot or cold; 'tis sometimes black, sometimes not, Altomarus. The same [1074]Melanelius proves out of Galen; and Hippocrates in his Book of Melancholy (if at least it be his), giving instance in a burning coal, which when it is hot, shines; when it is cold, looks black; and so doth the humour. This diversity of melancholy matter produceth diversity of effects. If it be within the [1075]body, and not putrified, it causeth black jaundice; if putrified, a quartan ague; if it break out to the skin, leprosy; if to parts, several maladies, as scurvy, &c. If it trouble the mind; as it is diversely mixed, it produceth several kinds of madness and dotage: of which in their place. SUBSECT. IV.—_Of the species or kinds of Melancholy_.
