    • n rumination The act or process of ruminating, or chewing the cud. The food of ruminants is entirely herbaceous, and consists chiefly of grass. This is rapidly cropped by grazing, and hastily swallowed, mixed with saliva. When its appetite is satisfied, the ruminant stands still, or oftener lies down, generally on its side. Then occurs a spasmodic action of the abdominal muscles and of the diaphragm, like a hiccup, which forces a bolus of grass, sodden in the fluids of the paunch, up the gullet and into the mouth, to be masticated or chewed at leisure. During this second chewing the cud is mixed with more saliva, thoroughly ground to pulp, and in this semi-fluid state it is finally swallowed. The cropped grass, when first swallowed, passes indifferently into either the rumen or the reticulum (which are in fact only two compartments of the cardiac division of the stomach, the gullet entering the stomach just at their junction), and in the ordinary peristaltic action of the stomach the fodder passes back and forth from one to the other. But there is an arrangement of muscular folds by means of which a canal may be formed that leads directly from the gullet past the rumen and reticulum into the psalterium, and by this channel the food, when returned after the rumination, may be conducted directly to the third stomach. Water drunk passes easily into any of the four stomachs according to circumstances. Neither the paunch nor the honeycomb is ever completely emptied of food; they have been found partly filled with sodden fodder in animals which have starved to death. It does not appear, as has been supposed, that the reticulum is specially concerned in modeling the boluses which are to be regurgitated. The regurgitation is effected by the reversed peristaltic action of the gullet. During the spasmodic action by which the sodden mass is driven against the opening of the gullet, and some of it forced into the gullet to be thrown up, it is prevented from passing into the psalterium partly by the narrowness of the opening between the reticulum and the psalterium, and partly by the resistance offered to the coarse mass by the close-pressed psalterial leaves or layers, which act like a fine grating. But when the mass is swallowed again in its now pulpifled and semifluid state, and is directed to the psalterium by the conformation of the parts, it readily soaks in through the psalterial layers, and thus reaches the abomasum or fourth stomach, where it is finally chymified by the action of the gastric juice, to which it is not before subjected. Rumination in man, when it is pathological, is also called merycism.

And all the world felt young again and blithe,

Then a sharp hiss breaks time and melody--
Spittle indrawn, old kisses new-desired.

O king! and keeps thine active spirit bound;
When busy war far other cares demands
Than ruminating thought and pale despair?

She ruminated long the deep,
And felt her freezing blood;
Approaching feet she heard behind,
Then swifter than the winged wind
She plunged into the flood.

As noon is marked by the twelve iron beats.

And the sound of a dead Europe hangs in the streets.
