It is impossible for even Mr. Darwin, inconsistent as it is with his whole theory, to deny all design in the constitution of nature. What is his law of heredity? Why should like beget like? Take two germ cells, one of a plant, another of an animal; no man by microscope or by chemical analysis, or by the magic power of the spectroscope, can detect the slightest difference between them, yet the one infallibly develops into a plant and the other into an animal. Take the germ of a fish and of a bird, and they are equally indistinguishable; yet the one always under all conditions develops into a fish and the other into a bird. Why is this? There is no physical force, whether light, heat, electricity, or anything else, which makes the slightest approximation to accounting for that fact. To say, as Stuart Mill would say, that it is an ultimate fact, and needs no explanation, is to say that there may be an effect without an adequate cause. The venerable R. E. Von Baer, the first naturalist in Russia, of whom Agassiz speaks in terms of such affectionate veneration in the "Atlantic Monthly" for January, 1874, has written a volume dated Dorpat, 1873, and entitled "Zum Streit ueber den Darwinismus." In that volume, as we learn from a German periodical, the author says: "The Darwinians lay great stress on heredity; but what is the law of heredity but a determination of something future? Is it not in its nature in the highest degree teleological? Indeed, is not the whole faculty of reproduction intended to introduce a new life-process? When a man looks at a dissected insect and examines its strings of eggs, and asks, Whence are they? the naturalist of our day has no answer to give, but that they were of necessity gradually produced by the changes in matter. When it is further asked, Why are they there? is it wrong to say, It is _in order that_ when the eggs are mature and fertilized, new individuals of the same form should be produced."
