McClure's was not, speaking biologically, a new species at all; it was only a mutation in which the recessive traits of the old magazine became dominant while the invaluable type was preserved. To speak more plainly, the literary magazine, as America knew it, had always printed news, matured news, often stale news, but still journalism. Read any number of Harper's in the 'seventies for proof.
Having no other means of making peace with the higher powers, he returned home sorrowful and malcontent, complaining to his confidants, "That every mutation or change in the state had hitherto been productive of some sma' advantage to him in his ain quiet affairs; but that the present had pize upon it! cost him one of the best penfeathers o' his wing."
These therefore being terminated, there can neither be an infinite mutation, according to a right line, nor can that which is always moved proceed according to a finished progression. Hence that which is always moved will proceed from the same to the same; and will thus form a periodic motion.
If species are so unstable, and so susceptible of mutation through such influences, why does that extinct form stand out so signally a monument of stability?
The Cumric and Gaelic have not only a great many thousand words in common, but also a remarkable grammatical feature, the mutation and dropping of certain initial consonants under certain circumstances, which feature is peculiar to the Celtic languages. The number of Sanscritic words which the Cumric and Gaelic possess is considerable.
The history of the Renaissance is not the history of arts, or of sciences, or of literature, or even of nations. It is the history of the attainment of self-conscious freedom by the human spirit manifested in the European races. It is no mere political mutation, no new fashion of art, no restoration of classical standards of taste.
At the same time there are some somatic sex-characters, e.g. in insects and birds, which do not appear to be correlated with changes in the gonads, and which are probably gametogenic, not somatogenic in origin. The theory of the heredity of somatogenic modifications is not in opposition to the mutation theory.
The question arises whether, when there is no embryonic recapitulation, it must be concluded that apparent adaptations are due to mutation and not to function or external conditions. One case of this kind is that of the limbs of Snakes, where, if we except the vestiges of hind limbs in the Pythons, there is no trace of limbs either in the embryo or after hatching.
It is evident that the required knowledge concerning the ancestry of a supposed mutation, must necessarily nearly all be acquired from the plants in the experimental garden. Obviously this rule is as simple in theory, as it is difficult to carry out in practice. First of all comes the book-keeping. The parents, grandparents and previous ancestors must be known individually.
Oh! it is a fearful thought, but one seldom entertained by the slaves of experience. Changes occur daily to all men; but, in the general case, each mere worldly position of ever-changing circumstances, possesses so much of the form and character of some prior one, that we are very soon reconciled to the idea of a variety composed of a mere mutation of the mixture of old elements.
