This mucus forms the glistening, shiny track which the snail leaves behind it, enabling it to glide easily and painlessly over rough substances which would otherwise lacerate its soft body.

For instance, when the secretory vessels of the kidneys become disobedient to the stimulus of the passing current of blood, no urine is separated or produced by them; their excretory mouths become filled with concreted mucus, or calculus matter, and in eight or ten days stupor and death supervenes in consequence of the retention of the feculent part of the blood.

It is possible that other things, such as dried pieces of mucus, may have been erroneously regarded as worms. General Considerations. In discussing obstetric anomalies we shall first consider those strange instances in which stages of parturition are unconscious and for some curious reason the pains of labor absent.

To evince this structure, the retina of an ox's eye was suspended in a glass of warm water, and forcibly torn in a few places; the edges of these parts appeared jagged and hairy, and did not contract, and become smooth like simple mucus, when it is distended till it breaks; which shews that it consists of fibres; and that its fibrous construction became still more distinct to the sight, by adding some caustic alkali to the water, as the adhering mucus was first eroded, and the hair-like fibres remained floating in the vessel.

This bird, it was asserted, by feeding on the berries, surrounded its beak with the viscid mucus they contain, to rid itself of which it rubbed its beak, in the course of flying, against the branches of trees, and thereby inserted the seed which gave birth to the new plant.

Remove all tight clothing from the neck, chest, and waist. Sweep the forefinger, covered with a handkerchief or towel, round the mouth, to free it from froth and mucus. Turn the body on the face, raising it a little, with the hands under the hips, to allow any water to run out from the air passages. Take only a moment for this.

They vary in size from the one hundred-thousandth to the one twenty-thousandth of a second of an inch in diameter, and appear at first hardly more than moving specks of semi-translucent mucus. Indeed, Burdach calls them "primordial mucous layers."

XL. The retina of an ox's eye was suspended in a glass of warm water, and forcibly torn in a few places; the edges of these parts appeared jagged and hairy, and did not contract and become smooth like simple mucus, when it is distended till it breaks; which evinced that it consisted of fibres.

At the University Hospital, Philadelphia, White has extracted, by median cystotomy, a long wax taper which had been used in masturbation. The cystoscopic examination in this case was negative, and the man's statements were disbelieved, but the operation was performed, and the taper was found curled up and covered by mucus and folds of the bladder.

He applied a thread, folded on itself several times, to the lips, thus stimulating them in a simple mechanical manner. Of 20 women, between the ages of 18 and 35, only 8 felt this as a merely mechanical operation, 4 felt a vaguely erotic element in the proceeding, 3 experienced a desire for coitus and in 5 there was actual sexual excitement with emission of mucus.
