These months are only approximate; later or earlier the rain-laden wind may drift up the water gate of the Colorado from the Gulf, and the land sets its seasons by the rain. The desert floras shame us with their cheerful adaptations to the seasonal limitations. Their whole duty is to flower and fruit, and they do it hardly, or with tropical luxuriance, as the rain admits.
My view is, then, that specific characters are usually not adaptations, that other characters of taxonomic value are some adaptive and some unrelated to conditions of life, and that while non-adaptive characters are due to spontaneous blastogenic variations or mutations, adaptive characters are due to the direct influence of stimuli, causing somatic modifications which become hereditary, in other words, to the inheritance of acquired characters.
I have seen her in a hundred varieties of that costume since then, and have grown familiar with the exhaustless diversity of its adaptations, but I defy the imagination of the greatest artist to devise a scheme of color and fabric that would again produce upon me the effect of enchanting surprise which I received from that quite simple and hasty toilet.
It is, in fact, only disease which can disintegrate the personality organized upon its adaptations, and induce a man of society to cease to act in a becoming manner; it is well known that a neurasthenic subject who begins to show the first symptoms of paranoia, may at first seem to be merely one who fails in good breeding.
And this most particularly in those spontaneous arts which, first in the field, without need of adaptations of material or avoidance of the already done, without need of using up the rejected possibilities of previous art, or awakening yet unknown emotions, are the simple, straightforward expression, each the earliest satisfactory one in its own line, of the long unexpressed, long integrated, organic wants and wishes of great races of men: the arts, for instance, which have given us that Hermes, Titian's pictures, and Michael Angelo's and Raphael's frescoes; given us Bach, Gluck, Mozart, the serener parts of Beethoven, music of yet reserved pathos, braced, spring-like strength, learned, select: arts which never go beyond the universal, averaged expression of the soul's desires, because the desires themselves are sifted, limited to the imperishable and unchangeable, like the artistic methods which embody them, reduced to the essential by the long delay of utterance, the long century long efforts to utter.
These things look like the cautious patting and petting of a spirited horse, preparatory to mounting him, when it is dreaded that he may give the rider a fall. And why the hasty after-indorsement of the decision, by the President and others? We cannot absolutely know that all these exact adaptations are the result of pre-concert.
In another class of adaptations the embryonic or larval stage is adapted to new conditions, while the adult condition is either less changed or not changed at all. One of the most obvious examples of this is the allantois in the Amniota. The embryos of Reptiles, Birds, and Mammals all develop two embryonic or foetal membranes, the amnion and the allantois.
We had plenty of blunders to confess, and there was no room for over-confidence; but the book prompted every earnest soldier among us to believe that we could make still better use of our experience, and to feel bolder in relying on his own judgment and courage in drawing new expedients from our peculiar circumstances and in developing new adaptations of military science to our own campaigns.
As we pass from the more to the less complicated animals we find a gradual simplification of the machinery until the machinery apparently disappears. With this simplification of the machinery we find the animals provided with less varied powers and with less delicate adaptations to conditions. But withal we find the fundamental powers of the living organisms the same.
Hence, in fact, the law of the Conditions of Existence is the higher law; as it includes, through the inheritance of former variations and adaptations, that of Unity of Type.
