"When we ask Mr. Darwin about the evolution of the battery of the electric eel, or about the evolution of the eye of the cuttlefish, or of the eye or ear of a human being, matters that his theory without much hesitation ought to explain, he hastily takes refuge under a confession of ignorance, replying that " it is impossible to conceive by what steps these wondrous organs have been produced." And when we ask him for the missing links he sends us, not, as Lyell does, to central Africa, but to "undiscovered [and undiscoverable] fossiliferous strata below the Silurian." And when we ask him a little more specifically about the origin of the species, and how four or five primeval forms or original germs could have developed into all the various forms of life that have existed and that now exist, he replies, "Our ignorance of the laws of variation is profound." And yet we hear on every hand that the hypotheses of naturalism are established!"
