Admitting to the full as highly probable, though not completely demonstrated, the applicability to living beings of the laws which have been ascertained with reference to dead matter, I feel constrained, at the same time, to admit the existence of a mysterious something lying beyond — a something...
Página 72 - For these reasons, we have no hesitation in adopting as our fundamental maxim, the " law of priority," viz. § 1. The name originally given by the founder of a group or the describer of a species should be permanently retained, to the exclusion of all subsequent synonyms (with the exceptions about to be noticed) . Having laid down this principle, we must next inquire into the limitations which are found necessary in carrying it into practice.

No more, it seems to me, than the laws of motion account for the union of oxygen and hydrogen to form water, though the ponderable...
