The fact that Professor Beale has discovered that what he calls bioplasm and germinal points or bioplasts may take on a distinct and separate color from tissue, when subjected to a solution of carmine in ammonia, is no evidence that he has penetrated the adytum of this sacred temple of Life, wherein lies the "mystery of mysteries." It is an important discovery so far as tracing tissue is concerned, but it admits him into no higher mystery within the temple built by God than another may attain to by the accidental discovery that the tissues may take on the same color in some other solution--by no means an improbable discovery. Carmine in ammonia is not the only solution that may aid science in the investigations now being carried forward by the vitalists and non-vitalists with so much bitterness and asperity of feeling between them; and now that Professor Beale has made _his_ happy discovery, it is by no means certain that some other equally persistent worker in this interesting field of inquiry may not hit upon quite as happy a discovery in the same or some equivalent direction--one that shall throw the bioplasmic theory as far into the shade as Mr. Cook thinks the bioplasts have already thrown the cells. But decidedly the most objectionable statement of Professor Beale, although one confidently re-affirmed by our "Boston Monday Lecturer," is that which makes bioplasm and bioplasts the only "living matter." We have already referred to the phrases "living matter" and "non-living matter" as altogether objectionable in biological statement, since they are more than half-way concessions to the materialists, who contemptuously order the vitalists to take a "back seat" in the discussions now going forward as to the true origin of life. But the objection we here make is less technical, and touches a far more vital point in the inquiry. It is true that Professor Beale speaks of "formed matter," as if it were a peculiar something--a sort of _tertium quid_--between living and non-living matter. But he distinctly avers that the substance which turns red in his carmine solutions is the "only living matter," and hence asserts, inferentially at least, that all other matter, in any and every living organism, is "dead matter." But we may just as confidently aver that no matter is living in any vital organism which has not been assimilated and built up into living membranous tissue capable of responding (in the case of man) to his will, as well as performing the autonomous functions of plants and the lower animals. For all these membranous tissues are innumerably thronged with bioplasts or plastide particles, not for the purposes of obedience to man's will, or of performing any autonomous function, but simply to supply the tissues with the necessary nutrient matter to make up for the constant waste that is going on in a healthy living organ. This waste is very much greater than has heretofore been supposed, so that the man or animal of
