Methionic :: Methionic (a.) Of, pertaining to, or designating, a sulphonic (thionic) acid derivative of methane, obtained as a stable white crystalline substance, CH2.(SO3H)2, which forms well defined salts..

Oxalan :: Oxalan (n.) A complex nitrogenous substance C3N3H5O3 obtained from alloxan (or when urea is fused with ethyl oxamate), as a stable white crystalline powder; -- called also oxaluramide..

Aphakia :: Aphakia (n.) An anomalous state of refraction caused by the absence of the crystalline lens, as after operations for cataract. The remedy is the use of powerful convex lenses..

Anisotropic :: Anisotropic (a.) Not isotropic; having different properties in different directions; thus, crystals of the isometric system are optically isotropic, but all other crystals are anisotropic..

Porphyry :: Porphyry (n.) A term used somewhat loosely to designate a rock consisting of a fine-grained base (usually feldspathic) through which crystals, as of feldspar or quartz, are disseminated. There are red, purple, and green varieties, which are highly esteemed as marbles..

Wagnerite :: Wagnerite (n.) A fluophosphate of magnesia, occurring in yellowish crystals, and also in massive forms..

Pyrophosphoric :: Pyrophosphoric (a.) Pertaining to, or designating, an acid, H4P2O7, which is obtained as a white crystalline substance. Its salts are obtained by heating the phosphates..

Effloresce :: Effloresce (v. i.) To become covered with a whitish crust or light crystallization, from a slow chemical change between some of the ingredients of the matter covered and an acid proceeding commonly from an external source; as, the walls of limestone caverns sometimes effloresce with nitrate of calcium in consequence of the action in consequence of nitric acid formed in the atmosphere..
