Latona (Gr. Λητω), in Grecian mythology, a daughter of the Titan Coenus and Phoebe, and mother of Apollo and Diana by Jupiter, to whom she was married before he wedded Juno. It is only by later writers that she is described not as the wife but concubine of Jupiter. According to the fable, Latona, when pregnant, and persecuted by the jealous Juno, could find no rest, the earth being afraid to receive her, while she was constantly pursued by the serpent Pytho. Finally she came to the floating isle of Delos, which gave her refuge, or which, as some accounts state, was created for her after all other parts of the earth had been cursed should they afford her rest. Symbolically Latona seems to have signified the primitive darkness whence sprung Apollo, or the light. She was worshipped only in connection with her children.

Laudanum, a name of uncertain origin applied to several tinctures of opium; it should be restricted, however, to. the officinal tincture, which is prepared with 2 1/2 oz. troy of opium to 2 pints of menstruum consisting of equal parts of water and alcohol. About 13 minims of 25 drops of this tincture are equivalent to a grain of opium. The strength of laudanum may be increased on exposure to evaporation; and when after standing some time it becomes thick, it should be administered with caution, especially to infants. The laudanum of Sydenham is a wine of opium, prepared with saffron, cinnamon, and cloves. It is nearly equivalent to the United States officinal wine of opium, and is slightly stronger. than ordinary laudanum. (See Opium.)
