Organon §44

Two similar diseases can neither fend off one another (as was said about dissimilar diseases in point i, §36-§37) nor suspend one another so that the older disease comes again after the new one has run its course (as was shown about dissimilar diseases in point ii, §38-§39). Nor can two similar diseases exist next to one another in the same organism, or form a double complicated disease (as has been shown about dissimilar diseases in point iii, §40-§41).
