of species has been really abandoned by Mr. Darwin himself, and is untenable. It is a misleading positive term, denoting negative effects, and, as made use of by those who would attribute to it the origin of man, is an irrational conception," "a puerile hypothesis" (MIVART, PROFESSOR ST. GEORGE, Lessons from Nature, London, 1876, pp. 280-331). Any who remember Professor Huxley's article on Darwin's Critics, in "The Contemporary Review," for November, 1871, will recall the strong terms in which he speaks of Mivart's scientific and philosophical competence. But Mivart holds nearly Professor Theophilus Parsons's and Owen's creed, that species have originated by a force interior, and not exterior, to the modified organism. To that position Darwin draws nearer and nearer. Among Darwinians there seems to be a conspiracy of silence as to this fact. Darwinism is becoming Owenism. Darwin himself is not a good Darwinian. [Applause.]

God be thanked that this age takes nothing for granted! No: it does take one thing for granted, its own superiority to all other ages; and yet one other thing, that there are not more things in heaven and earth than are dreamed of in its philosophy. But, my friends, the scientific method requires, that, when we run up our list of causes, electrical, physical, mental, spiritual, at the top, to reach on into the infinite, another class, -the unknown. Even in the nineteenth century, there are more things in heaven and earth than are dreamed of in our philosophy.

"THE Convertibility of the physical forces, the correlation of these with the vital, and the intimacy of that nexus between mental and bodily activity, which, explain it as we may, cannot be denied, all lead upward towards one and the same conclusion, the source of all Power in Mind; and that philosophical conclusion is the apex of a pyramid, which has its foundation in the primitive instincts of humanity." -DR. W. B. CARPENTER, Mental Physiology, chap. xx.

THE CONCESSIONS OF EVOLUTIONISTS.

THE small philosopher is a great character in New England. His fundamental rule of logical procedure is to guess at the half, and multiply by two. [Applause.] God be thanked for the diffusion of knowledge! God save us from the attendant temporary evils of arrogant sciolism in democratic ages! These are a necessary transitory stage in the progress of popular enlightenment which has just begun to dawn. in this yet dim Western world. A little knowledge is a dangerous thing; and it is our boast, that, in America, every man has a little knowledge. We must drink deep, or taste not the Pierian spring; but every breathlessly hurried free citizen now is endeavoring, to his honor, to have a taste at least; and yet we know how mercilessly commerce and greed, and the toil for daily bread, wrench parched lips away from the deep draught. Full popular enlightenment is popular sanity; penumbral popular enlightenment is often popular insanity; and yet the penumbral must precede the full radiance. The small philosopher is always a great character under representative institutions. He seems destined to reign long on the
