Such is a brief sketch of the characters and distribution of the persistent modifications, or stocks, of mankind at the present day. If we seek for direct evidence of how long this state of things has lasted, we shall find little enough, and that little far from satisfactory.
"Come and look at this, Miss Leighton," she called to Alma, who reluctantly approached. "What lines are these?" Mrs. Leighton asked, pointing to Beaton's pencil scratches. "They're suggestions of modifications," he replied. "I don't think they improve it much. What do you think, Alma?"
We are far too ignorant, in almost every case, to be enabled to assert that any part or organ is so unimportant for the welfare of a species, that modifications in its structure could not have been slowly accumulated by means of natural selection.
As to other creeds, it must be admitted that an acceptance of the teaching brought to us from beyond would deeply modify conventional Christianity. But these modifications would be rather in the direction of explanation and development than of contradiction.
To this short sight, a strip of paper, a bed of mint-leaves, a layer of yellow sand, a stream of water, a furrow made by the broom, or even lesser modifications are enough to transform the landscape; and the regiment, eager to reach home as fast as it can with its loot, halts uneasily on beholding this unfamiliar scenery.
Confining our attention to this common element, and omitting the consideration of minor diversities, we may now inquire into the grounds on which the theory rests, and the most plausible reasons which have been urged in support of it. To some minds it has been recommended by its apparent simplicity. It speaks only of one substance as existing in Nature under various modifications.
It is instructive to reflect on the wonderful diversity of the means for producing sound, possessed by the males alone, or by both sexes, in no less than six Orders. We thus learn how effectual sexual selection has been in leading to modifications which sometimes, as with the Homoptera, relate to important parts of the organisation.
If the war is still to be carried on, and surely the nation has shown no symptoms of slackening in its purpose, what modifications of it would General McClellan introduce? The only information that is vouchsafed us is, that he is to be the "conservative" candidate, a phrase that may mean too little or too much.
Many modifications of Cuvier's great divisions have been attempted. Some naturalists, for instance, have divided off a part of the Radiates and Articulates, insisting upon some special features of structure, and mistaking these for the more important and general characteristics of their respective plans.
However, the modifications in the general plan won't be serious. I want to talk to you about that." "Have you got contracts, then, already?" "No. Both the War Office and the Admiralty have told me they have all the explosives they want," he sneered. "But I've made a few inquiries, and I think that by the time my factory's up they'll be wanting more explosives than they can get.
