When, notwithstanding the use of issues, matter is formed in joints, or, when these fail to procure the absorption of what was formed before they were introduced, then one of two things must happen; either the abscess must be punctured, or it must be allowed to burst of its own accord. In general, I believe, it is most advantageous to allow the abscess to burst, without any interference, except the continuance of the issue, or the establishment of such new ones as circumstances, particularly the situation of the pain, may point out. If, however, it were at any time deemed proper to evacuate the matter, this ought to be done with a small trocar, at different times, in the manner recommended by Mr. Abernethy for the cure of lumber abscess. This is infinitely preferable to the barbarous practice which even some surgeons high in reputation advise and make use of, I mean the insertion of a seton through the abscess of the joint[101]. [101] Bell on Ulcers, p. 471. When the scrophulous suppuration ends in the ulcerative action, the cure is generally tedious. It is even doubted by some how far it is safe to attempt a speedy termination to the ulcer, as it is supposed, that, in this case, the disease may be driven to some other part: And so fearful are they of this dreadful event, that they are careful, by issues and new artificial sores, to continue the discharge after the original ulcer is healed. If I have been right in my view of this disease, it will appear, that this reasoning is false, and that the practice is both useless and troublesome. Even those who propose and defend the practice, do so not upon the principles of reason and judgment, or from logical deductions from the theory which they give of the disease, but upon imaginary apprehensions. We find, for instance, Mr. Bell saying, that, “till the disease is eradicated from the habit, all that should in general be done to the sores, is, to give as free and open vent to the matter as possible[102].” From this, we should, without doubt, expect, that he considered scrophula as dependent upon some peculiar humour which was to be expelled; but just before we are told, that this disease depends upon debility, particularly of the lymphatic system; a condition which it is not customary to talk of eradicating, or rooting out, or expelling. Upon the common principles of reasoning, Mr. Bell ought only to have forbid healing the sores, until the system was strengthened, otherwise the weakness would be driven or determined to some other part.
