. 3. de loc. affectis, cap. 6._ by Alexander, _lib. 1. cap.
16._ Rasis, _lib. 1. Continent. Tract. 9. lib. 1. cap. 16._ Avicenna and
most of our new writers. Th. Erastus makes two kinds; one perpetual, which
is head melancholy; the other interrupt, which comes and goes by fits,
which he subdivides into the other two kinds, so that all comes to the same
pass. Some again make four or five kinds, with Rodericus a Castro, _de
morbis mulier. lib. 2. cap. 3._ and Lod. Mercatus, who in his second book
_de mulier. affect. cap. 4._ will have that melancholy of nuns, widows, and
more ancient maids, to be a peculiar species of melancholy differing from
the rest: some will reduce enthusiasts, ecstatical and demoniacal persons
to this rank, adding [1085] love melancholy to the first, and lycanthropia.
The most received division is into three kinds. The first proceeds from the
sole fault of the brain, and is called head melancholy; the second
sympathetically proceeds from the whole body, when the whole temperature is
melancholy: the third ariseth from the bowels, liver, spleen, or membrane,
called _mesenterium_, named hypochondriacal or windy melancholy, which
[1086]Laurentius subdivides into three parts, from those three members,
hepatic, splenetic, mesaraic. Love melancholy, which Avicenna calls
_ilishi_: and Lycanthropia, which he calls _cucubuthe_, are commonly
included in head melancholy; but of this last, which Gerardus de Solo calls
_amoreus_, and most knight melancholy, with that of religious melancholy,
_virginum et viduarum_, maintained by Rod. a Castro and Mercatus, and the
other kinds of love melancholy, I will speak of apart by themselves in my
third partition. The three precedent species are the subject of my present
discourse, which I will anatomise and treat of through all their causes,
symptoms, cures, together and apart; that every man that is in any measure
affected with this malady, may know how to examine it in himself, and apply
remedies unto it.

It is a hard matter, I confess, to distinguish these three species one from
the other, to express their several causes, symptoms, cures, being that
they are so often confounded amongst themselves, having such affinity, that
they can scarce be discerned by the most accurate physicians; and so often
intermixed with other diseases, that the best experienced have been
plunged. Montanus _consil. 26_, names a patient that had this disease of
melancholy and caninus appetitus bo
