IN all which _Cases_, I humbly conceive, it may be _cur’d_ by Variety of respective _Means_, according to the different Quality of the CAUSE, whether _Frigid_, _Calid_, _Serous_, _Saltish_, or _Acrimonious_: Otherways it ceases (of itself) in process of Time, by good Conduct and keeping warm, &c. [Illustration] CHAP. XI. _Of the HEAD-ACH._ OF all the _Parts_ of the Body, the HEAD is most expos’d to _Pains_; that is, to a troublesome and grievous _Sensation_ of the _Membranous Parts_; proceeding from _Vapours_ of the noxious _Humours_; which ascending to the HEAD, distend and rend, in a manner, the _Membranes_ of the BRAIN. THE _Parts_ most commonly affected, are the _Hairy Scalp_, the _Pericranium_, and the _Diploe_; That is, the medullous _Duplicature_ of the CRANIUM, otherways call’d the _Meditullium_: For these _Parts_, by a continual _Solution_, when it happens so, are always most severely pain’d. But besides, in a _Woman_ that has conceiv’d, the _Pains_ commonly shift and move from one Place, to another, of the HEAD; and take certain _Intervals_, longer or shorter, betwixt their _Access_ and _Recess_. BUT as the _Infant_ grows, and exhausts a greater Quantity, or at last the _whole_ of the BLOOD; and as the _Humours_ fix in their proper Place: So this SYMPTOM gradually goes off, and quite ceases. HOWEVER, in case the _Accesses_ be long and violent, they may be discreetly _cur’d_ by repelling and mitigating _Applications_, or by peculiar _Corroboratives_ and _Discutients_, or proper _Alteratives_, according to the _Nature_ and _Quality_ of the CAUSE. I refer what may be farther added on this Head, to _Sect._ IX. _Chap._ 3. [Illustration] CHAP. XII. _Of the MEGRIM, or VERTIGO._ THIS _Symptom_ begins with a _Swimming_, _Giddiness_, or _Dizziness_ of the HEAD, and proceeds (in the _conceiv’d Woman_) from _Vapours_ of the _Humours_; which, ascending partly thro’ the _Veins_ and _Arteries_ tending to the BRAIN, and partly thro’ the OESOPHAGUS or _Gullet_, disturb the Animal Spirits. NOW This _Distemper_ is _Two-fold_, and distinguished by the Words VERTIGO and TENEBRICOSA; which last the _Arabian Physicians_ have call’d _Scotomia_, I suppose from the _Greek_ Word Σκοτος, _Tenebræ_, Darkness; and is now generally receiv’d by that Name. BUT because this sad _Affection_ is too common to both _Sexes_, young and old, I shall proceed to a farther Dilucidation of it, for the universal Good and Benefit of All.
