 ... two in conjunction to the facts of histology. He lays stress on the significance of functional adaptation, which I had described in 1866, under the head of cumulative adaptation, as the most important factor in evolution. Pointing out its influence in the cell-life of the tissues, he puts "cellular selection" above "personal selection," and shows how the finest conceivable adaptations in the structure of the tissue may be brought about quite mechanically, without preconceived plan. This "mechanical teleology" is a valuable extension of Darwin's monistic ...

... covered, particularly about the neck, with thick and shaggy hair. He has usually two dew claws on each of the hind legs; not, however, as in the one claw of other dogs, having a jointed attachment to the limb, but merely connected by the skin and some slight cellular substance. These excrescences should be cut off when the dog is young. The tail is slightly turned upwards and long, and almost as bushy as that of a fox, even in that variety whose coat is almost smooth. He is of a black colour or black prevails, mixed with ...

Nor is it remarkable that no type of ruin in the Southwest seems to connect these first terraced towns with the later not only terraced but also literally cellular buildings, which must be regarded nevertheless as developed from them. The reason for this will become evident ...

... nutty part has been deposited remains in the centre, as the milk, till the tiny embryo begins to sprout. As soon as it does so, the little knob which was at first so very small enlarges rapidly and absorbs the water, till it grows out into a big spongy cellular mass, which at last almost fills up the entire shell. At the same time, its other end pushes its way out through the soft hole, and then gives birth to a growing bud at the top—the future stem and leaves—and to a number of long threads beneath—the ...

Covering wall forms with tar paper nailed to the studding so as to form with the lagging a cellular covering is an excellent device and will serve in very cold weather if the sand and stone have been heated. From these simple precautions the methods used may range to the elaborate systems of housing described in the ...

... several drunken men showed special friendliness. One of these insisted upon showing us an idol, which, from his description, should have been a rather beautiful piece. It turned out to be a very crudely-made head, wrought in coarse, cellular lava. Considering the material, the work was really fine; nor was it a fragment broken from the body, as there had never been more than what we saw. From here, a yet more drunken dulcero insisted ...

... extreme interest, so that some reference to the actual structure of the hair and the hair-follicles is called for. The roots of the hair are formed in the hair-follicles, which may be described as little pear-shaped bags, formed either in the true skin or in the cellular tissue beneath it. Each hair-follicle, hair-sac, or hair-pit, as it is variously termed, bulges out at its deeper part, contracting to a long narrow neck as it passes to its skin. Near the surface of the latter the ...

In the wall of the follicle two layers are distinguished, the theca externa, which is more fibrous, and the theca interna, which is more cellular. In the connective tissue stroma of the ovary between the follicles are scattered, or in some cases aggregated, epithelioid cells known as the interstitial cells, and it is stated that the cells of the theca interna are exactly similar ...

First, the transmission is through the ordinary cellular tissue, and not through what are called the fibrous or vascular bundles. Second, the movement is a vital one, and is effected by contraction on the side toward which the bending takes place, rather than by turgescent tension of the opposite side. The tentacle is pulled over rather ...

It is composed of the most widely differing elements which, taken together, form the so-called protoplasm or cellular substance. And for all life established in nature the cell remains the constant and unchanging form element. It comprises the cell-protoplasm and a nucleus imbedded in it whose substance is known as the nucleoplasm. The nucleus is ...

... the sun? An eminent physiologist accounts for the presence of rudimentary organs, by supposing that they serve to excrete matter in excess, or matter injurious to the system; but can we suppose that the minute papilla, which often represents the pistil in male flowers, and which is formed of mere cellular tissue, can thus act? Can we suppose that rudimentary teeth, which are subsequently absorbed, are beneficial to the rapidly growing embryonic calf by removing matter so precious as phosphate of lime? When ...

... brittle wood fibres, which are of no use. The valuable fibres are, however, closely united with the wood and with each other in such an intimate fashion that it is impossible to separate them by any mechanical means. The whole cellular substance of the stem is bound together by some cementing materials which hold it in a compact mass, probably a salt of calcium and pectinic acid. The art of preparing flax is a process of getting rid of the worthless wood fibres ...

These cells are composed, first, of the insoluble cellular tissue; second, of phosphate of chalk and fatty phosphoric bodies; third, of soluble cerealine. In order to study the composition and the nature of this tissue, it must be completely isolated, and this result is obtained in the ...

I had observed also, that the inner coat had no connexion either with the outer or with the nucleus, except at its origin; and that with relation to the outer coat it was generally inverted, while it always agreed in direction with the nucleus. And, lastly, that at ...

The eye of the Pecten presents a retina, a cornea, a lens of cellular structure like our own. There is even that peculiar inversion of retinal elements which is not met with, in general, in the retina of the invertebrates. Now, the origin of molluscs may be a debated question, but, whatever opinion we hold, all are agreed that molluscs ...

... of the vegetable kingdom, scarcely any hold a more important place than barks, whether for medicinal, manufacturing, or other purposes. The structure and formation of all barks are essentially very similar, being composed of cellular and fibrous tissue. The cell contents of these tissues, however, vary much in different plants; and, for this reason, we have fibrous or soft, woody, hard, and even stony barks. To explain everything which relates to the structure of bark would lead us into long details which ...

The capacity of this organ for holding active substances in its cellular parts, is one of its marked physiological distinctions. In instances of poisoning by arsenic, antimony, strychnine and other poisonous compounds, we turn to the liver, in conducting our analyses, as if it were the central depot of the foreign matter. It is, practically, the same ...

Still more, on the first day, when it is nothing but a flat cellular disk? I certainly cannot bring myself to believe that this disk feels. Yet if it does not, there must be some time in the three weeks, between the first day and the day of hatching, when, as a concomitant, or a consequence, ...

And why should I not complete my thought: the boars have muddied the clear stream; natural history, youth's glorious study, has, by dint of cellular improvements, become a hateful and repulsive thing. Well, if I write for men of learning, for philosophers, who, one day, will try to some extent to unravel the tough problem of instinct, I write also, I write above all things, for the young, I want to make them love the natural ...
