IPECACUANHA (ip"'-e-kak"-u-an'a) , or IPECACUAN (-kak'u-an) (the native Brazilian name), in botany, the plants producing the drug so named. In phar- macy: (1) The dried root of Cephselis ipecacuanha, a conchonaceous plant from Brazil. The ipecacuanha from that country is called annulated, to distin- guish it from the striated kind from Peru. The active ingredients reside chiefly in the cortex. It contains a feeble alkaloid called ceretin. Its preparation are pills, powders, lozenges, and wine. In large doses it is an emetic; in smaller ones it is an expectorant and an altera- tive. It is considered a specific in dysen- tery. Ipecacuanha, made into ointment, is a counter-irritant. (2) Various other plants produce a similar drug, as, for example, all the Alsodinese, a tribe of Violacex. IPEK, a town in Montenegro, on the river Drin, about 400 miles northwest of Uskub.

IPHIGENIA (if"i-je-nra), in Greek legend, a daughter of Agamemnon and Clytemnestra. When the Greeks, going to the Trojan War, were detaitied by contrary winds at Aulis, they were in- formed by Calchas, the soothsayer, that, to appease the gods, they must sacrifice Iphigenia to Diana, because her father had killed the favorite stag of that god- dess. Rather than shed the blood of his daughter, Agamemnon, as chief of the Grecian forces, commanded one of his heralds to order the army to disperse. After much solicitation from the other chiefs, Agamemnon consented, however, to immolate his daughter for the com- mon good of Greece; but as soon as Cal- chas had taken the knife and was about to strike the fatal blow Iphigenia sud- denly disappeared, and a goat of uncom- mon size was found in her place. This supernatural change animated the Greeks, the wind suddenly became favor- able, and the combined fleets set sail for Aulis. Iphigenia's innocence had ex- cited the compassion of the goddess Diana, who carried her to Taurica, where she intrusted her with the care of her temple, whence she subsequently fled with her brother Orestes and his friend Pylades.
