ratio, in proportion as the simple inflammation and ulceration of the same parts, and in the same circumstances, is tedious. Thus, a deep wound in a healthy person is pretty long of healing; but, in a scrophulous person, it is much more so. Simple inflammation of a gland is still more tedious than the same extent of inflammation in cellular substance; and scrophulous inflammation is still longer of running its progress; but the proportion betwixt the duration of the scrophulous inflammation, in these two cases, is not exactly as the duration of the simple inflammation of the two, compared with each other, but is in an increased ratio. When scrophulous inflammation is excited in the vicinity of a part already possessing this action, it occasionally removes the action from that part, in the same way as inducing simple inflammation by a blister in one part cures the same disease in another part in the vicinity. It was an observation of this fact which made it be considered as part of the description of scrophulous tumors and ulcers, that they not unfrequently disappear in one place, whilst they show themselves in another; but, in every instance, this disappearance is an effect, and not a cause; for we uniformly observe, that, before it takes place, the new part has begun to inflame or swell. With regard to the diagnosis of scrophula, it is impossible to say any thing satisfactory; because, as long as the inflammation remains trifling, and the skin sound, it is very difficult, if not impossible, to distinguish a scrophulous swelling from any other of a different kind. Much assistance has been supposed to be derived from the situation of the tumors, most of those which appear in the neck being considered as scrophulous; but this is certainly a false principle. From the same method of reasoning, most swellings in the groin have been considered as venereal, whilst many are of a very different nature, and not a few scrophulous. The best plan is to attend to the appearance of the body in general, and to the presence or absence of the sign of a scrophulous system; next, whether any ulceration be present, by the absorption of matter, from which these swellings may have been produced. If these be present in a system not possessing the marks of scrophula, the probability of the tumor being scrophulous is less; but, if the system be evidently scrophulous, then we must consider, whether the glands, originally swelled by the absorption of matter, have assumed the slow inflammation of a scrophulous nature, or have assumed a different species of inflammation, dependent upon the peculiarity of the matter; for they can scarcely be supposed to be simply inflamed. Scrophulous swellings of the lymphatic glands are generally soft and doughy, and frequently give the feel of containing a fluid long before suppuration has taken place. They are at first free from pain, and, in mild cases, even toward the end, the pain is inconsiderable.
