Note 895 — Chapter V · (continued 3)

Dr. Robert Williams (Encyclopædia of the Medical Sciences, London, 1847, 4to, p. 688) says, ‘The diagnosis between gout and rheumatism is often exceedingly difficult, so much so that nosologists have given a mixed class, or rheumatic gout. Mr. Hunter warmly opposed this compound appellation, for, in his opinion, no two distinct diseases, or even distinct diatheses, can co-exist in the same constitution; a law, it must be admitted, to have many exceptions.’ Compare Watson's Principles and Practice of Physic, London, 1857, vol. i. p. 312; ‘acting upon the aphorism of John Hunter (an aphorism, however, which requires some qualification), that two diseases or actions cannot go on in a part at the same time.’ According to another authority, ‘There can be little doubt that two or more zymotic processes do often go on simultaneously in the blood and body; a fact of profound interest to the pathologist, and worthy of attentive investigation.’ Report on the Public Health for 1847, in Journal of the Statistical Society, vol. xi. p. 168, London, 1848. See also, on the co-existence of specific poisons, Erichsen's Surgery, 2nd edit., London, 1857, p. 430. Mr. Paget, in his striking and eminently suggestive Lectures on Pathology, London, 1853, vol. ii. pp. 537, 538, has made some interesting remarks on one part of the theory of co-existence; and his observations, so far as they go, tend to corroborate Hunter's view. He has put very forcibly the antagonism between cancer and other specific diseases; and especially between the cancerous diathesis and the tuberculous.
