The branches of the anterior temporal lymphatics sometimes terminate in glands above the zygomah process; these glands are often wanting, and always Very small when they are found, but I have seen them, occasionally, enlarged from disease. The principal temporal absorbents :pass through glands over and under the parotid gland; the former I have known indurated and enlarged to the size of a hen's egg, which gave suspicion of cancerous aliection in the parotid itself, which, notwithstanding, lasted many years without any bad consequence; the ab- sorbents which pass over the parotid, pass through its substance, and pass under it, belong to the temporal absorbents, and terminate both in the su- perficial and deep-(seated plexus of the neck. The occipital absorbents, or those accompanying the occipital artery, terminate in a gland, or glands, on, or behind the mammillary process, and hardly ever wanting; these glands often swell to a very large size, inflame and suppurate, front the af- fection of their absorbents in the 1mm capitis, a disease often owing to animals whatever. neglect in not washing children's heads every day, from their birth, till they have passed their second year.
