[NL. (Bergmann, 1782), paratus invented by Griffin for ascertaining the percentage of ammonia in solutions. Ammonian (a-mō'ni-an), a. [L. * Ammonia nus, ammoniated (a-mō'ni-ā-ted), a. niate.] Combined with ammonia. [ ammo ammonia, or spirits of hartshorn. (See aqua ammon iæ, under aqua.) Among the more important salts of ammonia is ammonium chlorid, or sal ammoniac, NH4Cl, which formerly was the source from which all ammonium salts were prepared. It is largely used in dyeing, and in soldering and tinning. At present ammonium sulphate, (NH4)2SO4, is the starting-point for the manufacture of ammonium salts, being made in large quantity from gas liquor. It is also used as a fertilizer. There are several ammonium carbonates. The commercial article, called ters are a dorsolateral line, conical head with terminal mouth and protractile jaws, post median anus, narrow sub orbitals, enlarged suboperculum, widely cleft branchial apertures, lamelliform pseudo branch iæ, a long dorsal fin, a long sub-post median anal fin with articulated rays, and the absence of ventral fins. The species are of small size, and ammonium carbamate. See ammonium. 2. [ cap.] In zool.: (a) An old quasi-generic name of Spirula. Breyn, 1732. (b) A genus of arachnidans.
