[131] The way that corn can attract moisture. [132] Specific attraction of the "proper" quality; _cf._ p. 85, note 3 (130). [133] Theory of evaporation insufficient to account for it. _cf._ p. 104, note 1 (156). [134] Playful suggestion of free-will in the urine. [135] Specific attraction, _cf._ p. 87, note 2 (233). [136] _i.e._ there would be no selective action. [137] Nasal mucus was supposed to be the non-utilizable part of the nutriment conveyed to the brain, _cf._ p. 214, note 3 (297). [138] He means from its origin in the liver (_i.e._ in the three hepatic veins). His idea was that the upper division took nutriment to heart, lungs, head, etc., and the lower division to lower part of body. On the relation of right auricle to vena cava and right ventricle, _cf._ p. 321, notes 4 (398) and 5 (399). [139] We arrive at our belief by excluding other possibilities. [140] _i.e._ the mechanistic physicists. _cf._ pp. 45-47. [141] _cf._ p. 85, note 3 (130). [142] The subject of _anadosis_ is taken up in the next chapter. _cf._ also p. 62, note 1 (96). [143] On Erasistratus _v._ Introd. p. xii. His view that the stomach exerts no _holké_, or attraction, is dealt with more fully in Book III., chap. viii. [144] _i.e._ the tissues. [145] _cf._ p. 291. [146] _Peristalsis_ may be used here to translate Gk. _peristolé_, meaning the contraction and dilation of muscle-fibres _circularly_ round a lumen, _cf._ p. 263, note 2 (341). [147] For a demonstration that this phenomenon is a conclusive proof neither of _peristolé_ nor of real vital _attraction_, but is found even in dead bodies _v._ p. 267. [148] This was Erasistratus's favourite principle, known in Latin as the "horror vacui" and in English as "Nature's abhorrence of a vacuum," although these terms are not an exact translation of the Greek. [Greek: to kenoumenon] probably means _the vacuum_, not the _matter evacuated_, although Galen elsewhere uses [Greek: kenoô] in the latter (non-classical) sense, _e.g._ pp. 67, 215. Akolouthia is a _following-up_, a _sequence_, almost a _consequence_. [149] _v._ p. 123. [150] _cf._ Book II., chap. i. [151] Vital factor necessary over and above the mechanical. [152] _cf._ p. 119, note 2 (173). [153] pp. 91, 93. [154] _i.e._ the part below the liver; _cf._ p. 91, note 2 (138). [155] Renal veins. [156] _cf._ p. 87, note 3 (133). [157] [Greek: koilên]: the usual reading is [Greek: koilian], which would make it "from the region of the alimentary canal." _cf._ p. 118, note 1 (171). [158] Not at an earlier stage, when it is still on its way from the alimentary canal to the liver. [159] _i.e._ a renal vein. [160] In a toast, the third cup was drunk to Zeus Sôtêr (the Saviour).
