There are physical reasons that induce us to believe that the case is so, and there are several observations which seem to confirm it. Those who have served in time of war, have all been witnesses of some singular instance or other of the effects of the percussion of the air; there are instances of people killed on the field, without being touched by the ball. I was told by officers, men of veracity, that at the battle of Fontanoy, a ball broke the thigh bone of a soldier in the Dutch army, without touching him; another saw a man who was rendered paralytic on one side, by a ball whizing past him. Curious observers know, that nothing so greatly fatigues an army as a high wind, even the centinels are tired, without marching; the reason is, that a high wind occasions a kind of general contusion, which of course produces weariness. I do not know but some of the effects of lightening may be imputed to the same cause. I shall add nothing to what Mr. Bilguer says concerning the effects of a contusion; he is sufficiently explicit on this head; and as I have already treated the subject pretty largely in my book termed Advice to the People, I shall only observe, that in the wounds made by musket-ball, the effect of the general concussion is not very considerable, but the danger, in such cases, proceeds from the topical contusion accompanying the wound, the small quantity of blood commonly discharged from it; and lastly, as Mr. Le Dran remarks, because the instant a man receives a gunshot wound, he is struck with a sudden dread he cannot possibly resist. There seems to me to be three reasons for this dread, of which even the wounded person himself is not altogether conscious; in the first place, the idea that gunshot wounds are dangerous; secondly, because the degree of the hurt is not known; thirdly, the instantaneous effect of the concussion, which renders a man much more susceptible of fear. There is a point of time when courage is useless. I shall beg leave, in this place, to insert a case I had from the eye-witnesses, and which demonstrates the bad effect of apprehension on wounded patients. Two officers, in the service of France, were wounded in the last campaign but one; one of them very dangerously, the other, who had been a prisoner a little time before, and had been extremely ill used, but very slightly; they were carried to the same place, and lodged in the same apartment; the first expected to die, but nevertheless recovered in a short time; the second hoped to be cured very quickly, and his wound, a superficial one in the leg, did not discover the least sign of danger. The place they were in was surprized, and they were informed they were made prisoners; the idea of what he had suffered, made so strong an impression on the latter, that he instantly found himself indisposed; the following dressing the wound appeared mortified, every remedy proved useless, and he died in a few days. Tissot.
[38] The troublesome symptoms which I have here enumerated, happen seldomer when the limb is entirely carried off by the ball, although the concussion caused by the compression of the air must be greater in this case, than when the ball has only grazed; a circumstance which might induce one to call in question the justness of my remarks in this section. But these doubts will vanish, when we reflect, that in a contusion there is no discharge of blood, whereas it is very considerable in cases where the limb is intirely carried off; and thus, the remedy is here a consequence of the accident itself, since this hemorrhage effects what we would wish to effect by artificial bleeding; in contusions, where there is no discharge of blood, it removes obstructions, and disperses the extravasated humours, which are the consequences of concussion.
SECT. [XXXII].
As I object to the amputation of contused limbs, it is reasonable I should point out the method of treating such contusions: I prevent the troublesome symptoms they produce, or disperse them if they have already appeared, by frequent bleedings, and by the exhibition of such medicines as attenuate the blood, resolve what is too gross, remove what is obstructed, and render fit to be reabsorbed what is extravasated. I join with them such as, by gently evacuating by stool, unload the vessels; and I afterwards give such things as brace up the fibres, and restore the natural crasis of the blood.
I have found no medicine more effectual to attenuate the blood, and resist the febrile disposition, than a powder, consisting of nitre, Epsom salt, cream of tartar, and true Armenian bole[39].

SECT. [XXXIII].
The external applications for a contused limb should vary, according to circumstances, or according as the contusion has caused a mortified slough, or has not. If it has not, but nevertheless the bone is fractured, the applications should be of a very mild nature. In such a case I make no incisions, but I endeavour to bring the two ends of the bone together, to place them in their natural position, and to keep them in it, by means of compresses and bandages, as in the common simple fractures: I constantly stupe the whole dressings with discutient and vulnerary fomentations[40], and exactly follow the plan laid down [§ XIV.] by which means I have almost always happily cured contusions of this kind.
If the contusion has caused a mortified slough, and has at the same time shattered the bone, we must begin by separating the dead slough from the sound parts, with a scalpel; we must make deep incisions, and neglect no means proper for promoting the discussion or suppuration; and the fracture of the bone must be treated agreeably to the method recommended [§ XXIV.] This case requires great vigilance in the care of it, and we find ourselves amply recompensed for our labour, by the pleasure of accomplishing the cure of these unfortunate patients, either compleat, or at least as much so, as can possibly be obtained in their situation.
