ANT (ănt). Syn. Emm′et, Pis′mire*‡ (pĭz′-); Formi′ca, L.; Fourmi, Fr.; Ameise, Ger.; Æmet, Sax. This well-known little insect belongs to the family formic′′idæ, and the order hymenop′tera. Like the bee, it is a social animal, lives in communities which may be compared to well-regulated republics, and is of three sexes—male, female, neuter. Those belonging to the last alone labour and take care of the ova and young. The red ant contains FORMIC ACID (acid of ants), and a peculiar RESINOUS OIL. Both of these may be obtained by maceration in rectified spirit. A tincture so prepared, and flavoured with aromatics, constitutes Hoffman’s Eau de Magnanimité, once greatly esteemed as an aphrodisiac. See Formica, Formic Acid, Formyle, &c.

ANTAC′ID (-tăs′-ĭd). Syn. Antac′idus, L.; Antacide, &c., Fr.; Säuretilgend, &c., Ger. An agent which neutralises acids or removes acidity. (See below.)

ANTAC′IDS (-tăs′-ĭdz). Syn. Antac′ida, L.; Antacides, &c., Fr. Antacid substances. In medicine, &c., substances which remove or prevent acidity of the stomach, and thus tend to relieve heartburn, dyspepsia, and diarrhœa.

The principal antacids are potassa, soda, ammonia, lime, and magnesia, with their carbonates and bicarbonates. Ammonia is one of the most powerful, and when the acidity is conjoined with nausea and faintness, or is accompanied with symptoms of nervous derangement or hysteria, is undoubtedly the best; when great irritability of the coats of the stomach exist, POTASH is to be preferred; when the acidity is accompanied with diarrhœa, carbonate of lime (prepared chalk), lime-water, or Carara-water; and when with costiveness, MAGNESIA. They may be advantageously combined with some simple aromatic, as ginger, cinnamon, or peppermint. Their preparation, doses, administration, &c., will be found under each in its alphabetical place; and formulæ containing them, under Draughts, Lozenges, Mixtures, &c.
