The earth is all alive and covered with papillae. The largest pond is as sensitive to atmospheric changes as the globule of mercury in its tube. One attraction in coming to the woods to live was that I should have leisure and opportunity to see the Spring come in. The ice in the pond at length begins to be honeycombed, and I can set my heel in it as I walk.
He can blow himself up by taking in air and water, until he becomes a bloated wretch instead of the fairly decent thing he is in his normal moments. He can bite, he can make a noise with his jaws, and can eject water from his mouth to some distance. Besides all this, he erects papillae on his skin like thorns, and secretes in the skin of his belly a carmine fluid that makes a permanent stain.
The epidermis is therefore growing while the spermatogenesis is taking place. In August and September the epidermic papillae begin to be obvious, and from this time till February a continuous increase in the papillae and their pigmentation occur. Geoffrey Smith argues that the development of this somatic character occurs while the testes are inactive and unchanged.
Dermoid cysts of the ovary may consist only of a wall of connective tissue lined with epidermis and containing distinctly epidermic scales which, however, may be rolled up in firm masses of a more or less soapy consistency; this variety is called by Orth epidermoid cyst; or, according to Warren, a form of cyst made up of skin containing small and ill-defined papillae, but rich in hair follicles and sebaceous glands.
Castration during the breeding season causes the external pigmented layer with its papillae to be cast off very soon that is to say, it has the same effect as the normal discharge of the spermatozoa.
As my visits to the beech clump were repeated, I managed to divide my finds into three categories. In the first, which was the most numerous, the mushroom was furnished underneath with little radiating leaves. In the second, the lower surface was lined with a thick pad pricked with hardly visible holes. In the third, it bristled with tiny spots similar to the papillae on a cat's tongue.
Thiersch contends that healing of a granulated surface results first from a conversion of the soft, vascular granulation-papillae, by contraction of some of their elements into young connective-tissue cells, into "dry, cicatricial papillae," actually approximating the surrounding tissues, thus diminishing the area to be covered by epidermis; and, secondly, by the covering of these papillae by epidermic cells.
To appreciate the flavor of these wild apples requires vigorous and healthy senses, papillae firm and erect on the tongue and palate, not easily flattened and tamed. From my experience with wild apples, I can understand that there may be reason for a savage's preferring many kinds of food which the civilized man rejects. The former has the palate of an out-door man.
Ichthyosis is a disease of the skin characterized by a morbid development of the papillae and thickening of the epidermic lamellae; according as the skin is affected over a larger or smaller area, or only the epithelial lining of the follicles, it is known as ichthyosis diffusa, or ichthyosis follicularis.
The figure on the left of the plate represents a curious cluster of papillae which project from one side of the mouth, and are the opening of the oviduct.
