[26] In Greek _anadosis_. This process includes two stages: (1) transmission of food from alimentary canal to liver (rather more than our "absorption"); (2) further transmission from liver to tissues. _Anadosis_ is lit. a yielding-up, a "delivery;" it may sometimes be rendered "dispersal." "Distribution" (_diadosis_) is a further stage; _cf._ p. 163, note 4 (230). [27] _cf._ p. 9. [28] Since heat and cold tend to cause diffusion and condensation respectively. [29] Lit. _haematopoietic_. _cf._ p. 11, note 3 (20). [30] Lit. _peptic_. [31] Lit. _sphygmic_. [32] _Genesis_ corresponds to the intrauterine life, or what we may call _embryogeny_. _Alteration_ here means histogenesis or tissue-production; _shaping_ or _moulding_ (in Greek _diaplasis_) means the ordering of these tissues into organs (organogenesis). [33] _cf._ p. 25, note 4 (49). [34] Note inadequate analogy of semen with fertilised seeds of plants (_i.e._ of gamete with zygote). Strictly speaking, of course, semen corresponds to pollen. _cf._ p. 130, note 2 (188). [35] _i.e._ the four primary qualities; _cf._ chap. iii. _supra_. [36] Various secondary or derivative differences in the tissues. Note pre-eminence of sense of touch. [37] _De Anima_, ii. _et seq._ [38] Lit. _homoeomerous_ = of similar parts throughout, "the same all through." He refers to the elementary tissues, conceived as not being susceptible of further analysis. [39] That is, by the bodily eye, and not by the mind's eye. The observer is here called an _autoptes_ or "eye-witness." Our medical term _autopsy_ thus means literally a _persona inspection_ of internal parts, ordinarily hidden. [40] _i.e._ "alteration" is the earlier of the two stages which constitute embryogeny or "genesis." _cf._ p. 18, note 1 (32). [41] The terms Galen actually uses are: _ostopoietic_, _neuropoietic_, _chondropoietic_. [42] As we should say, _parenchyma_ (a term used by Erasistratus). [43] Those were all the elemental tissues that Aristotle, for example, had recognized; other tissues (_e.g._ flesh or muscle) he believed to be complexes of these. [44] Or _tunics_. [45] _i.e._ tissues. [46] As, for example, Aristotle had held; _cf._ p. 23, note 3 (43). Galen added many new tissues to those described by Aristotle. [47] Lit. _synthesis_. [48] By this is meant the _duodenum_, considered as an outgrowth or prolongation of the stomach towards the intestines. [49] _cf._ p. 19, note 2 (33). [50] Lit. the _auxetic_ or _incremental_ faculty. [51] _i.e._ to the alterative and shaping faculties (histogenetic and organogenetic). [52] If the reading is correct we can only suppose that Galen meant _the embryo_.
