    valves, like those in the veins. Their walls are so thin, tliat these folds give them the appearance of being knotted. 391. At ceriain points, the lymphatic vessels pass through distinct, soft bodies, peculiar to themselves, which are called lymphatic glands^ which are to these vessels what the mesen- teric glands are to the lacteals. The lymphatic glands vary in form and in size. They are extremely vascular, and appear to consist of a collection of minute vessels. These glands aro, found in different parts of the body, but are most numerous in the groins, axilla, or arm-pits, neck, and cavities of the chest and abdomen. Ohservation. From exposure to cold, these glands are frequently enlarged and inflamed. They are known under the name of kernels. They are often diseased, particu- larly in scrofula, or king's evil. PHYSIOLOGY OF-THE LYMPHATIC VESSELS. 392. Though the lacteals and lymphatics resemble each other in their structure and termination, yet they differ as to the nature of the fluids which they convey, as well as the nature of their functions. The lacteals open into the small intestine, and possess the power of rejecting all substances in the passing aliment, but the chyle. The lymphatics, on the contrary, not only imbibe all the various constituents of the body, both fluid and solid, when their vitality has ceased, but they absorb foreign and extraneous substances, when pre- sented to their mouths. 393. The varieties of absorption are, the In-ter-sii'tial, Rec-re-men-ti'tial^ Ex-cre-men-tltial^ Cu-ta'ne-ous^ Res-pvra- to-ry, Ve'nous, and the Lac'te-al. 391. Describe the Irmphatic glands. What observation is given in regard to these glands ? 392—i03. Give the physiologTj of the lymphatic ves- eels. 392. Explain the difference between the lacteals and lymphatics. 393. Name the varieties of absorption.
