Nature herself permits, as has been stated, in some cases, the simultaneous occurrence of two (indeed, of three) natural disease in one and the same body. This complication, however, it must be remarked, happens only in the case of two dissimilar disease, which according to the eternal laws of nature do not remove, do not annihilate and cannot cure one another, but, as it seems, both (or all three) remain, as it were, separate in the organism, and each takes possession of the parts and systems peculiarly appropriate to it, which, on account of the want of resemblance of these maladies to each other, can very well happen without disparagement to the unity of life.
