Of the inhabitant of the sea we have already spoken in tbe article Aliment. Fish in the earlier ages were seldom eaten, and are mentioned as food in two plaees only of tbe Odyssey, when the crew of Ulysses were in extreme distress. The insects and vermes afford us many luxuries, and even the botanical riches of the ocean furnish food for the inhabitants of the higher latitudes. The sponges, the zoophytes, and lithophytes, are tbe work and the habitation of animals. The first and the last only afford medicinal substances; the sponges when burnt »see Sckofula) ; and the corals now dis- used, but formerly employed as absorbents. In the arts, the fiici, confervae and alga are used for the production of natron.
T*he effects of sea voyages are, at first, a violent and distressing sickness, often occurring even in those accustomed to a sea life, when they have li ed for a short time on shore. Small quantities of brandy, sometimes a little hartshorn, or laudanum, with water, will succeed in relieving it j sometimes a draught of sea water. It arises from the unaccustomed motion, and is only effectually stopped when the constitution has for a little time experienced it. In general, during a sea voyage the belly is costive, but the health is seldom impaired, except from scurvy. See Phthisis and Scorbutus.
SEA
SEACACUL. An appellation in the works of Se- rapion and Avicenna of a root resembling ginger, brought from India, and recommended as a provocative. It was suspected to be the eryngo, and hence this root,
byShakspeart and others, has been arranged among the aphrodisiacs. Modern authors suppose that by this term the ginseng was meant.
SEBA'CEjEIGLA NDULiE, vel MI LI ARES, (from sebum, suet) ; small glands secreting a sebum, to soften and polish the skin. Many of these are about the nose, where their contents are often hardened and when the matter is squeezed out it resembles a worm with a black head, for the hardened sebum is moulded in the duct.
