[53] _i.e._ not the pre-natal development of tissue already described. _cf._ chap. vi. [54] Administration, lit. "economy." [55] The _activation_ or _functioning_ of this faculty, the faculty _in actual operation_. _cf._ p. 3, note 2 (6). [56] "Un rapport commun et une affinité" (Daremberg). "Societatem aliquam cognationemque in qualitatibus" (Linacre). _cf._ p. 36, note 2 (61). [57] Lit. "necessity"; more _restrictive_, however, than our "law of Nature." _cf._ p. 314, note 1 (386). [58] His point is that no great change, in colours or in anything else, can take place at one step. [59] Not quite our "waste _products_," since these are considered as being partly synthetic, whereas the Greek _perittomata_ were simply superfluous substances which could not be used and were thrown aside. [60] Note "our natures," _cf._ p. 12, note 4 (25); p. 47, note 1 (75). [61] The term [Greek: oikeios], here rendered _appropriate_, is explained on p. 33. _cf._ also footnote on same page. Linacre often translated it _conveniens_, and it may usually be rendered _proper_, _peculiar_, _own special_, or _own particular_ in English. Sometimes it is almost equal to _akin_, _cognate_, _related_: _cf._ p. 319, note 2 (394). With Galen's [Greek: oikeios] and [Greek: allotrios] we may compare the German terms _eigen_ and _fremd_ used by Aberhalden in connection with his theory of defensive ferments in the blood-serum. [62] Transit, _cf._ p. 6, note 1 (10). [63] _i.e._ of the living organism, _cf._ p. 2, note 1 (5). [64] _i.e._ with nutrition. [65] We might perhaps say, more shortly, "assimilation of food to feeder," or, "of food to fed"; Linacre renders, "nutrimenti cum nutrito assimilatio." [66] Lit. _prosphysis_, _i.e._ attachment, implantation. [67] Lit. _prosthesis_, "apposition." One is almost tempted to retain the terms _prosthesis_ and _prosphysis_ in translation, as they obviously correspond much more closely to Galen's physiological conceptions than any English or semi-English words can. [68] Lit. _phthisis_. _cf._ p. 6, note 2 (11). Now means _tuberculosis_ only. [69] More literally, "chymified." In _anasarca_ the subcutaneous tissue is soft, and pits on pressure. In the "white" disease referred to here (by which is probably meant _nodular leprosy_) the same tissues are indurated and "brawny." The principle of certain diseases being best explained as cases of _arrest_ at various stages of the metabolic path is recognized in modern pathology, although of course the instances given by Galen are too crude to stand. [70] The effects of _oxidation_ attributed to the heat which accompanies it? _cf._ p. 141, note 1 (199); p. 254, note 1 (332).
