СКАЧАТЬ Distempers, requires least the Application of violent or uncertain Remedies: Tho’ its pain be very intense, it comes very slow to its Period: Generally it is many Years, or the imprudent Application of Medicines, that brings it into the noble Parts, so as to endanger Life; purging by the Bowels hath frequently brought it into the Stomach; external Applications of repellent Plaisters have drove it into the Head; Applications of Mercurial Plaisters have brought on Paralytick Disorders: As we are not certainly acquainted with the particular Nature of the Gouty Matter, it is uncertain how to apply. That there is somewhat in the Part, not natural to the Body, which occasions the Pain, we know; what it is particularly we know not; the common Method of Nature is to evacuate it by the Pores of the Skin at certain Seasons, which requires the Part to be kept warm, and to attend upon the Operations of Nature for Relief; this, and the Uncertainty of Medicinal Applications, have brought Patience and Flannel to be Proverbial to the Gout.

      Since the Cure of the Gout doth not with Safety admit the Application of sudden or violent Remedies, nor the Nature thereof require them; Physicians have, with very great Prudence, turned their Thoughts to other Methods of Cure; for this End, it was very proper to consider the Gout as the Distemper of the Rich and the Lazy, that it flows chiefly from Idleness and Fulness of Bread; that Persons afflicted therewith have naturally keen Appetites, and are apt to indulge in larger Quantities and cruder Kinds of Food, than the digestive Powers are able to deal with; that it chiefly happens to sedentary People; that upon the Approach of a Fit of the Gout, and during the Paroxysm, there are evident Marks of Indigestion in the Stomach and Bowels. If we add hereto the actual Relief that many Persons have found in the Use of a proper Diet, we shall not be at a Loss for a Reason, why Physicians should expect to find a more certain and easy Method of Cure in the Gout by Diet, than by any other Means.

      It is not my Design at present to enter into the particular History of the Gout; this is very well known, and so accurately described by Dr. Sydenham, that it is needless; nor to enter into any long Detail of the History of the Alimentary Powers; this is likewise sufficiently known; nor to raise any Altercations about the particular Quality of the Gouty Matter, which is unknown, neither would the Knowledge thereof be much to my present Purpose. It will suffice to examine with Accuracy the Nature of Animal and Vegetable Diet, and the Habits they produce in the human Body, and to apply this to the Nature and Symptoms of the Gout.

      The Knowledge of the particular Quality of the Gouty Matter is not absolutely necessary to our present Purpose; it is sufficient if it be made to appear, that the whole Habit of the Body may be changed by Diet. An Animal is entirely composed of the Food it is nourished by, the first Stamen, or Principle of Life, is most exceedingly small; and all that it afterwards receives its Growth from, may properly enough be called its Food: In oviparous Animals, and the same happens in viviparous ones, (tho’ it be not so much within the Compass of our Observation) the first Nourishment is the White of the Egg, a Fluid very analogous to the Serum of the Blood, and the Subject of the Encrease is originally so small as almost to escape the strictest Enquiry.

      Many, if not most Authors, who have entered into the particular Quality of the Gouty Matter, have placed it in an acrimonious acid Salt, and upon that Scheme have gone into the Method of a Milk and Vegetable Diet for the Cure. The Cure upon this Scheme seems to me not very rational, because Milk and Vegetables in their natural State tend to Acidity; and the Chalky Substance of the Gout and Stone in the Bladder (which are pretty near akin) are soluble only by Aqua fortis, which is the strongest Acid. The Digestion of Animal Food, which is found to encourage, if not occasion the Gout, naturally tends to Alcalescence; and therefore there is more Reason to conclude the Gouty Matter to be Alkaline than Acid; but the Truth is, there are no evident Marks of either Acid or Alkali in the Animal Juices of an healthy Body, nor of any other Salt but Sea Salt, which is taken in with the Food, and as it is incapable of Change, passes thro’ the Vessels of the Body. There is indeed an Acidity discoverable in the Bowels and lacteal Vessels, which is doubtless owing to the acid Food, for it doth not change its Nature, till it be thoroughly assimilated with the Blood in several Circulations; for even in the Chyle an Acid is sometimes discoverable: This Acid is lost in the Milk, which is but one Change farther, tho’ even in this it is evident there is some Tendency that Way, because of its Disposition to turn sowre by standing. As there is doubtless Air in the Blood, there must be somewhat Nitrous, because there is no Air without Nitre, and Nitre is an Acid, but cannot come within Imagination of occasioning the Gout. That the Gout should consist in an Acid, and be curable by acessent Aliment, the Gouty Chalk dissolved only by Acids, and the Aliment that occasions it alkalescent, would be very strange. On the contrary, there is as strong Evidence that the Gouty Matter is not perfect Alkali, neither is there any such Thing in the Juices of an healthy Body; for tho’ Animal Juices naturally tend to Alkalescence, they putrify before they arrive at that State, so as to be incapable of Circulation: The Disposition of Animal Juices this Way is so strong, that if they were not continually diluted by fresh Portions of Chyle, they would arrive at that putrescent Alkaline State that would destroy the Animal, as is evident in the Case of Animals starved to Death. Twenty Days Fasting will not diminish the Quantity of the Blood so much as a large Bleeding, and in some Kinds of Consumptions the Diminution of the Solids and Fluids is much greater than could happen by being starved; but in the Case before us, the Juices turning Alkaline and Corrosive affect the tender Fibres of the Brain, and the Animal dies feverish and delirious: On the contrary, People have lived above twenty four Days upon Water only, which can happen no otherwise than by diluting the Fluids, and consequently keeping them from this Alkaline State. In short, if the Juices of an Animal Body were either Acid or Alkaline, so as to cause an Ebullition by Mixture of their Opposites, they would burst the Vessels.

      I shall consider Vegetable Substances with regard to Diet, in the first Place, because they are the Original Food of all Animals, who either immediately are nourished thereby, or else feed upon such Animals as are nourished by them.

      Vegetables receive their Food from the Air and Earth, by means of several Recipient Vessels placed in the Root and Bark, (analogous to the Lacteals in Animals) conveyed and diluted by a sufficient Quantity of Water: This Food thus received, which I shall beg Leave to call Vegetable Chyle, is digested and assimilated in the Course of Circulation, through the Vessels of the Plant, till it is converted into Vegetable Substance, and is formed into the several differing Vegetable Juices, Gums, and Resins, that are peculiar to each Species of Plants. The Remainder, after the proper Separations, is evaporated thro’ the Pores of the Skin and through the Leaves, in the Manner of Animal Transpiration. I content myself here with this short Hint of Vegetable Nutrition, because I have treated it more at large and expresly in another Place: It is more material at present to examine the several Juices which circulate in the Vessels of Vegetables, because, in regard to Diet, they will appear to be the Matter of Animal Nutrition; for the Vessels of Plants are no other than meer Earth bound or connected together with Oyl, by the Means of some very powerful Attraction: This Earth is undissoluble by the utmost Force of Fire, since after burning a Plant in the open Fire, we find it left entire.

      The Chyle of Plants seems to be made up of whatever Parts in the Earth are soluble in Water, so as to be capable of being received into the Absorbent or Recipient Vessels of Plants, before taken Notice of; and consequently may consist of Salts, Oyls, Fumes of Minerals, Metals, and other fossil Bodies, the putrified Parts of Animals and Vegetables. In its first State it is, to be sure, very crude; but by the Structure and Fabrick of the Plant, and the various Vessels it is strained thro’, it is changed, elaborated, secreted, and assimilated into the Substance of the Plant; whence it follows, that in Vegetables are contained Salts, Oyl, Water, and Earth, and probably Metals too, for the Ashes of Vegetables yield somewhat which the Load-Stone attracts.

      This Juice, when it first enters the Root, is Earthy, Watry, Poor, and Acid, it is in the Form of a fine and subtle Water; the nearer it is to the Root, the more it retains of its proper Nature, the further it is from the Root, and the more Action it hath sustained it approaches nearer to a Vegetable Nature, as will appear by pursuing it a little further. In the Trunk and Branches it is further prepared, tho’ even here it is Watry and Acid, as appears by tapping Trees at the proper Season: It is more concocted in the Bud, where the Leaves coming to be unfolded, serve СКАЧАТЬ
