(Fer"ret-eye`) n. (Zoöl.) The spur-winged goose; — so called from the red circle around the eyes.

Ferretto
(Fer*ret"to) n. [It. ferretto di Spagna, dim. of ferro iron, fr. L. ferrum.] Copper sulphide, used to color glass. Hebert.

Ferri-
(Fer"ri-) (Chem.) A combining form indicating ferric iron as an ingredient; as, ferricyanide.

Ferriage
(Fer"ri*age) n. [From Ferry.] The price or fare to be paid for passage at a ferry.

Ferric
(Fer"ric) a. [L. ferrum iron: cf. F. ferrique. See Ferrous.] Pertaining to, derived from, or containing iron. Specifically (Chem.), denoting those compounds in which iron has a higher valence than in the ferrous compounds; as, ferric oxide; ferric acid.

Ferric acid (Chem.), an acid, H₂FeO₄, which is not known in the free state, but forms definite salts, analogous to the chromates and sulphates. — Ferric oxide (Chem.), sesquioxide of iron, Fe₂O₃; hematite. See Hematite.

Ferricyanate
(Fer`ri*cy"a*nate) n. [Ferri- + cyanate.] (Chem.) A salt of ferricyanic acid; a ferricyanide.

Ferricyanic
(Fer`ri*cy*an"ic) a. [Ferri- + cyanic.] (Chem.) Pertaining to, or derived from, a ferricyanide.

Ferricyanic acid (Chem.), a brown crystalline substance, H₆(CN)₁₂Fe₂, obtained from potassium ferricyanide, and regarded as the type of the ferricyanides; — called also hydro-ferricyanic acid, hydrogen ferricyanide, etc.

Ferricyanide
(Fer`ri*cy"a*nide) n. [Ferri- + cyanide.] (Chem.) One of a complex series of double cyanides of ferric iron and some other base.

Potassium ferricyanide (Chem.), red prussiate of potash; a dark, red, crystalline salt, K₆(CN)₁₂Fe₂, consisting of the double cyanide of potassium and ferric iron. From it is derived the ferrous ferricyanate, Turnbull's blue.

Ferrier
(Fer"ri*er) n. A ferryman. Calthrop.

Ferriferous
(Fer*rif"er*ous) a. [L. ferrum iron + -ferous: cf. F. ferrifère.] Producing or yielding iron.

(Fer`ri*prus"sic) a. [Ferri- + prussic.] (Chem.) Ferricyanic. [R.]

Ferro-
(Fer"ro-) (Chem.) A prefix, or combining form, indicating ferrous iron as an ingredient; as, ferrocyanide.

Ferrocalcite
(Fer`ro*cal"cite) n. [Ferro- + calcite.] Limestone containing a large percentage of iron carbonate, and hence turning brown on exposure.

Ferrocyanate
(Fer`ro*cy"a*nate) n. [Ferro- + cyanate: cf. F. ferrocyanate.] (Chem.) A salt of ferrocyanic acid; a ferrocyanide.

Ferrocyanic
(Fer`ro*cy*an"ic) a. [Ferro- + cyanic: cf. F. ferrocyanique.] (Chem.) Pertaining to, derived from, or designating, a ferrocyanide.

ferrocyanic acid (Chem.), a white crystalline substance, H₄(CN)₆Fe, of strong acid properties, obtained from potassium ferrocyanide, and regarded as the type of the ferrocyanides; — called also hydro-ferrocyanic acid, hydrogen ferrocyanide. etc.
