By this we may see how cautious we ought to be not to proceed in a Method contrary to the Dictates of Nature; for if we do, we consequently disturb her regular Motions, upon which she oftentimes commences a new Work, which, if it does not tend to the Subversion of the whole Oeconomy, there ensues a Permutation of the Disease, by the Translation of the Matter from one Part to another.
It would be impossible to recount all the obscure Motions Nature makes use of to accomplish such Ends: We will only mention some where the Disease has been perfectly changed from what it was before by such Methods. Mear gives us an Instance of a Dropsie of the Breast, which succeeded an ill-cured Hydrocele. Hildanus observes, that an inveterate Ulcer of the left Leg being unhappily healed up, the Patient died of a Pleurisy some Months after.
To this I may add an Observation of a Man that had an old Ulcer on each Leg, which being attempted to be cured, as the Matter gradually lessened, he was deprived of his Sight. There was no Alteration to be observed in the Eyes of this Person, but only a Dilatation of the Pupils, as is generally observed in a Gutta Serena, which was judged to be his Case. In short, upon the running of the Sores, though he had been perfectly blind, he effectually recovered his Sight again.
I will not tire you, Sir, with the Recital of any more Cases of this Nature. What has been hitherto said, I hope is sufficient to incline you to believe, that the immediate Cause of the Death of the Child I spoke of in the former part of the Letter was the Suppression of the Matter, which had continued to discharge in such large Quantities so long together. And that such a sudden Stoppage of a Discharge of Matter may procure a Patient’s Death, though the Symptoms that proceed may be different. I have likewise shewn the Difficulty there is in Diverting the Tendency of the Matter to a Part, and mentioned how one Disease is sometimes converted into another: But of what Use these Remarks may be I leave you to judge. To me it seems reasonable enough to suppose, that as a regular Method of Practice is not the Effect of a Man’s Sagacity, but the Product of repeated Experiences, every thing that occurs may tend, by a proper Application, to the Illustration of the Art. What else has made some Men so famous for their Prognosticks? Had not our great Master Hippocrates a Respect to the Suppression of the Discharge of Matter from Ulcers, when he expressed himself thus, Ulcus lividum & siccum, aut cum virore pallidum lethale est? And this we have known to be true in several Cases.
Well then, does not this sufficiently prove, that where we have Cause to fear a Suppression of the Discharge, we ought to remove any Impediment that may embarass Nature in her Work, and advise a proper Method to promote the precipitating the morbific Matter? For so shall we, by joining our Forces with those of Nature, still keep her in due Course; and that when she is grown languid, and departing from her former Measures.
You must excuse me, if I digress a little to take notice of an Observation that some Authors have made, viz. That from a dangerous Fracture of the Skull, after Death the Liver has been often found impostumated. They have been likewise very sollicitous to know which way the Matter could be conveyed to so remote a Viscus; but it would be needless for me to offer what has been said in this Case, because it seems to be evident enough, that a Part of it is reassumed by the Vessels; which, with that should have been discharged from the Mass of Blood, is by the Circulation deposited in that Part. But here we may start a considerable Problem, which is, How comes it to pass that the Morbific Matter if it’s Discharge is suppressed, is thrown upon the Liver rather than any other Part? In order to the Solution of this, we ought to consider, That the Spleen is subservient to the Liver in performing its Office, by giving the Blood a Check in it’s Progress, whereby it’s Velocity is lessened; otherwise so thick a Juice as the Bile could not be separated from it. Now the Motion of the Blood being rendered abundantly slower in this Part, it is no wonder that the Morbific Particles separate themselves from it, while the Filtration is carrying on, and by their Assemblage form an Abscess in the Part.
You may perhaps expect, Sir, that I should make an Apology to excuse the Length of my Letter; but I assure you, the Pleasure I have taken in writing it would oblige me to make it of a larger Extent, if I did not find I should be forced to take notice of some things, which may perhaps have a Place elsewhere. I have only this to add, that if through the little time I have taken to write it in, I have in any part omitted to pay that Respect as is due to you, I shall very readily ask your Pardon. In the mean time I must own my self to be,
Your very much obliged Servant,
Wm. Beckett.
