After the animal has finished eating, the food in the rumen is divided into parts large enough to be returned through the esophagus to the mouth. These are the cuds. The second chewing, or mastication, of the food is more complete than the first. The time taken for a portion of the food to leave the rumen, be remasticated, and returned to the stomach, is about one minute. It is estimated that the cow spends seven hours a day nmiinating the One of the first of sickness in a cow is the absence of rumination. After the second mas- tication of the food, and when it is well mixed with the saliva, or mouth fluid, it is again swal- lowed and instead of passing to the nimen, it enters tlic esophageal groove. In going through this muscular canal, tlic fluid part passes to the reticuhun and the solid part to the omasum. The reticulimi is the smallest of the four compartments of the stomach. It opens through the esophageal groove into l^oth the nmicn and the omasum. The inner lining of the reticulum is arranged like tlie cells of a honeycomb. Each cell is about one-half an inch across and has from four to six sides. It is in the cells of the reticular part of the stomach that foreign bodies, such as small stones, nails, pieces of wire, and the like, arc deposited. Occasionally sharp-pointed foreign bodies work their way through the wall of the reticulum, and, on account of the nearness of the reticulum to the heart, enter the heart and cause the death of the animal. The omastun, or third compartment, receives the solid ]:)arts of the food after the second mastication. The inner mucous layer of the o
