by reason of the ignorance of the exorbitant Qua∣lities, the cause of the Distemperature cannot be found out.
VII. Diseases of the Dis∣simular or Organical Parts. The other kind or General Head of Diseases is of the Organical Parts, which are said to be vi∣cious or faulty, with respect to their Conformation; or with respect to their Magnitude, when they are either greater or less than they ought to be; or with regard to their Number, when therein they exceed, or are defective; or as to their situa∣tion, when they are not rightly placed; or as to their Figure, when it is not such as it ought to be; or with respect to their Connexion, when they are at too great distance from each other, or if they be overmuch crowded together, stretched, comprest, loosened, or grown too stiff.
VIII. Some Dis∣eases afflict only some parts, o∣thers the whole Body. There is also another Division of Diseases into Universal and Particular: Univeral Diseases are such as afflict the whole Body, as Agues and Fe∣vers. Others Particular, which only affect one part of the Body, as the Brain, Lungs, Throat. But to theend that we may be able to understand the chief Diseases of the Body; we shall consider them in the following Order.
IX. Pain of the Head, or Headach. The First Disease, and which hath its seat in the Membrans of the Head, is the HEADACH, which is a Pain, or troublesom Sensation of the Head, proceeding from the Exorbitant Figures of the Blood, which spoil the Temperament thereof. For when the Animal Spirits, being too violent∣ly agitated by reason of a too Cholerick and Glewy Arterial Dew, are driven through the Ar∣teries, to the Head, and the Filaments and Mem∣brans of the Brain, they forthwith disorderly twitch, corrode, prick and cut the same, and find∣ing the pores through which they would make their way, not corresponding with them in Great∣ness and Figure, they by their force slit them up, and thereby produce an exquisit pain in the Head. Hence in the cure of this Disease there is made use of Blood▪letting, and other things conducing to the changing of the Distemper of the Blood, and to drive away the sharp particles, which are got into the most sensible Membrans of the Brain. Purging Medicines are also used, whereof some are more proper to expel these, and others, other particles; such as are Aqucous and Oleous Medicaments, which also stop the too swift motion of the Animal Spirits in the Blood.
X. Phrensie. PHRENSY or Raving is a violent agi∣tation of the Brain and Membrans thereof, caused by the excessive heat of the Blood, and its being filled with sharp and other malignant particles, which entring the Pores and Membrans of the Brain, do frequently cause an Inflammation there. Which then happens when Triangular Particles light upon Round Pores, whereupon in every such Pore, there are left three little spaces, because of the threefold surface, for the filling up of which spaces, the subtil matter presseth in with more abundance, by the rushing in whereof the Parts and Humours become agitated and disturbed. Whereupon the Glandula Pinealis is no longer in a condition to discharge its function, because these Animal Spirits are no longer subject to any Rule, but as Refractory Souldiers and Deserters, cast off the Yoke, and course it up and down without Rule or Discipline. Wherefore Opiates are commend∣ed for the cure of this Disease, which both reduce
the Raging Spirits to rest and composure, by clo∣sing up the Nerves, as it were, with Bird-lime, and stop the irregular motion of the sharp parti∣cles, which before did cut the Fibres, and little Branches of the Nerves, that those Fibres, which before were stretched out like Cords, do run toge∣ther into twisted Knots and Bunches, which Knots stop the passage of the Spirits through the Nerves, and so hinders them from being transmitted to all the parts of the Body, and consequently from dis∣charging the wonted functions. Refrigerating or Cooling Medicaments are likewise of use in this di∣stemper; as for Example, the Chymical Prepara∣tion called Nitrum Perlatum, which being dissol∣ved in Water, is found to be of very good use in this case, because it fixeth the Spirits and the Blood, and at the same time opens Obstructions; as also Distill'd Vinegar, Antimony Diaphoretick, and Powder of Pearl, Coral, &c.
XI. Melancho∣ly. MELANCHOLY which is commonly defined to be a Doating, without a Fever or Ra∣ving; is a Delirium or Doating, proceeding from the sadness of the Patient, whereby the Animal Spirits are moved more slowly than they are wont. This distemper of the Blood, is commonly the pro∣duct of a vicious Sowre Humour in the Blood, by means whereof the Animal Spirits are darkned and condensed, which roving through the former footsteps left in the Brain, and rebounding from them, represent the same Images to the Soul; and accordingly Melancholy Persons think the things they have once conceived to be always present with them. Wherefore Alterating Remedies are much used in this Disease, and particularly such as abound with much Volatil Salt, as all Spirituous Matters do, as by Example, the Juice of Betony, Scurvygrass, Brooklime, Chickweed and such like, by means whereof the Ropy and viscous distempe∣rature of the Blood is amended.
XII. Madnes•• MADNESS is another kind of Doating, accompanied with great Rage and Alienation of Mind, without a Fever, proceeding from the ir∣regular motion of the Animal Spirits being infla∣med, and turned into a fiery Nature. For the Spirits being excited by some outward cause, and inflamed, range about through the Brain, but more especially about the Glandula Pinealis, and rushing like Lightning into the Brain and Muscles, do put the Glandula out of the Souls command, which being deluded by these Spirits, and depri∣ved of all her command over the Body, can no longer guide or govern it; whence proceed so ma∣ny undecent Gestures, Fightings, Quarrels, Bawl∣ings, &c. In order to the stopping of this Ef∣fervescence of the Blood, ponderous Remedies are made use of, as Lapis Prunellae, Saccharum Sa∣turni, or Sugar of Lead, Crabs Eyes, Laudanum Opiatum, Sanguis Draconis, &c. Decoctions also made of some ponderous sorts of Wood, are profi∣table in this case, as which by their heavy and hard Particles, do stop the motion of the Blood.
XIII. Lethargy. LETHARGY is an irresistible inclinati∣on to Sleep, accompanied with great forgetfulness, caused by an Obstruction of the Pores of the Brain, by a thick and gross Humour, and the want of Animal Spirits. This Disease is also in a great measure caused by Steams and Vapours that are mingled with a Slimy, Ropy Due, which being condensed into Water overwhelm the Brain, and
