The maggots may be destroyed, by frequently shifting the bandages, linnen, cloaths, and coverings of the bed; by the application of the balsams I have already spoken of, which destroy these insects and prevent putrefaction; by constantly keeping on the bed-clothes, a linnen cloth dipt in tincture of aloes or vitriol. But care must be taken that the tincture of aloes does not touch the affected limb, much less the sores themselves, lest part of it should be absorbed, and occasion a diarrhæa; although in other respects aloes powerfully resists putrefaction, and is sometimes a useful vulnerary. FOOTNOTES: [26] At present, since we know that pus is only a corruption of the crassamentum of the blood, it is easier, perhaps, than formerly, to explain why an inflammatory denseness of the blood terminates sometimes in an abscess, and at other times in a compleat recovery without one. Dr. Pringle, to whom we are indebted for so many useful discoveries, which have thrown a new light on the theory and practice of physic, was the first who pointed out the true manner in which pus was formed, concerning which so many conjectures had been made; and Mr. Gaber has demonstrated it very particularly by a number of very curious experiments. TISSOT. SECT. XXVI. I have had under my care, during the course of this late bloody war, a great number of wounded limbs, torn and shattered by cannon and musket balls, by the bursting of bomb-shells and grenades, by grape-shot, &c. I cured them without ever performing amputation, by the method described in the two preceding sections, although there were bones broken and shattered, large blood vessels divided, the flesh miserably lacerated, and limbs carried off in the manner I have described § XXI. Others, such as I have described § XXIV. in which the bones were split up as high as the articulation; all which circumstances might make us reasonably apprehend a tedious and difficult cure, too plentiful a suppuration, hemorrhages, violent inflammation, excessive corruption, mortification and death. It will perhaps be asked me, Of those men so terribly wounded, whom you attempted to cure without the means of amputation, did none die? I shall return an answer by and bye. It will be further objected to me, that I have not taken notice of the os humeri, or the thigh bone being shattered; and it will be asked me, What must be done in cases where either of these bones are fissured as far as their upper extremities, in such a manner that we cannot hope to procure their coalition by means of any bandage? And finally, it will be remarked, I have not mentioned the wounding the brachial or crural arteries, or the large branches of these which pass between the radius and ulna, or tibia and fibula, called in both parts the inter-osseous arteries, whether these wounds be accompanied with a fracture of the bones, or otherwise. I shall reply to these two last objections, after having answered the first question in the following section.
