[217] [Why will some scientific men persist in separating, so strongly, religion and science, as if _both_ could not be practised? This is what the “master of science” appears to think. Each _student_ of science may well apply the following lines: “It is your duty to go on steadfastly, unwaveringly, _ohne Hast, ohne Rast_, conscious that you interpret, to the best of your finite ability, your conceptions of the truths of science, equally conscious that whatever may be the immediate result of your labours, they must eventually fulfil the aspiration which tends _ad majorem Dei gloriam_.”--C. Carter Blake _On the Doctrine of Final Causes_ (_Hastings Philosophical Society_, meeting of January 13, 1864).--EDITOR.] [218] Robin, _Mémoire sur la Production du Blastoderme_ (_Journal de Physiologie_, p. 358, 1862). [219] It is thus that we do not see realised in man that general law which decrees that animal species are large in proportion to the continent which they inhabit; the mean size of the mammalia, in particular, is regularly proportional to the extent of Australia, America, the ancient continent, and the bottom of the ocean. [220] Compare Mitchell, _An Essay upon the Causes of the Different Colours_, etc. (_Philosophical Transactions_, 1745.) [221] “Sole colorari homines non dubium, eosque autem ut nigrescant non constat.” Albinus, _De Sede et Causa Coloris Æthiopum_, p. 12. He also says, still speaking of Negroes, that they are coloured, “quod suum parentes colorem in liberos propagant ...; æthiops fœmina si cum mare æthiope rem habuerit, æthiopem, ni quid forte natura ludat, gignit; alba si cum albo, album.”--_Ibidem_, p. 10. It is in some manner the permanence of a declared type. [222] _Dissertation Physique sur les Différences des Traits du Visage_, p. 17. [223] See above, p. 85.
