k; 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_.

When the matter is divers and confused, how should it otherwise be, but
that the species should be divers and confused? Many new and old writers
have spoken confusedly of it, confounding melancholy and madness, as [1076]
Heurnius, Guianerius, Gordonius, Salustius Salvianus, Jason Pratensis,
Savanarola, that will have madness no other than melancholy in extent,
differing (as I have said) in degrees. Some make two distinct species, as
Ruffus Ephesius, an old writer, Constantinus Africanus, Aretaeus, [1077]
Aurelianus, [1078]Paulus Aegineta: others acknowledge a multitude of kinds,
and leave them indefinite, as Aetius in his _Tetrabiblos_, [1079]Avicenna,
_lib. 3. Fen. 1. Tract. 4. cap. 18._ Arculanus, _cap. 16. in 9. Rasis_.
Montanus, _med. part. 1._ [1080]"If natural melancholy be adust, it maketh
one kind; if blood, another; if choler, a third, differing from the first;
and so many several opinions there are about the kinds, as there be men
themselves." [1081]Hercules de Saxonia sets down two kinds, "material and
immaterial; one from spirits alone, the other from humours and spirits."
Savanarola, _Rub. 11. Tract. 6. cap. 1. de aegritud. capitis_, will have
the kinds to be infinite; one from the mirach, called _myrachialis_ of the
Arabians; another _stomachalis_, from the stomach; another from the liver,
heart, womb, haemorrhoids, [1082]"one beginning, another consummate."
Melancthon seconds him, [1083]"as the humour is diversely adust and mixed,
so are the species divers;" but what these men speak of species I think
ought to be understood of symptoms; and so doth [1084] Arculanus interpret
himself: infinite species, _id est_, symptoms; and in that sense, as Jo.
Gorrheus acknowledgeth in his medicinal definitions, the species are
infinite, but they may be reduced to three kinds by reason of their seat;
head, body, and hypochrondries. This threefold division is approved by
Hippocrates in his Book of Melancholy, (if it be his, which some suspect)
by Galen, _lib
