86 will not be absolutely different and entirely disparate from that of the spinal cord, of which it is the continuation and terminal knob, but will rather be a carrying out of the same kind of thing. This whole method of consideration belongs to the Homology of Richard Owen referred to above. On the other hand, it seems to me that the following explanation of the nature of the flower from its final cause, suggested by an Italian whose name has escaped me, is a far more satisfactory account to give. The end of the corolla is – (1.) Protection of the pistil and the stamina; (2.) by means of it the purified saps are prepared, which are concentrated in the pollen and germs; (3.) from the glands of its base the essential oil distils which, for the most part as a fragrant vapour, surrounding the anthers and pistil, protects them to a certain extent from the influence of the damp air. It is also one of the advantages of final causes that every efficient cause always ultimately rests upon something that cannot be fathomed, a force of nature, i.e., a qualitas occulta, and, therefore, it can only give a relative explanation; while the final cause within its sphere affords a sufficient and perfect explanation. It is true we are only perfectly content when we know both the efficient cause, also called by Aristotle, and the final cause, , at once and yet separately, as their concurrence, their wonderful working together, then surprises us, and on account of it the best appears as the absolutely necessary, and the necessary again as if it were merely the best and not necessary; for then arises in us the dim perception that both causes, however different may be their origin, are yet connected in the root, in the nature of the thing in itself. But such a twofold knowledge is seldom attainable; in organised nature, because the efficient cause is seldom known to us; in unorganised nature, because the final cause remains problematical. However, I will illustrate this by a couple of examples as good as I find within the range of my physiological knowledge, for
