Satiny, acicular crystals, which are rather more soluble in water than those of the sulphate.
Ferrous lactate is a greenish-white salt; and when pure, forms small acicular or prismatic crystals, which have a sweetish ferruginous taste, and are soluble in about 48 parts of cold and in 12 parts of boiling water.
A zeolite occuring in groups of glassy acicular crystals, and in masses which often have a radiated structure.
A kind of crystallite having a (slender) acicular form.
Defn: A zeolite occuring in groups of glassy acicular crystals, and in masses which often have a radiated structure.

After treating the latter with animal charcoal, dissolving in ether and evaporating the latter, there remain colorless, acicular crystals of the odor and taste of vanilla.
Such an adulteration can be detected with the microscope, since vanillin crystallizes in acicular crystals, and benzoic acid in lamina, which can be readily recognized.
Acicular crystals are also to be met with, more yellow than red in color, and are sometimes present in great abundance, although they may be wholly absent.
Yellow, acicular crystals, insoluble in cold alcohol, ether, and water.
Under the microscope butterine does not appear to consist of acicular crystals of fat, but of irregular masses, containing a few butter globules, particles of curd, and crystals of salt.
By re-solution in alcohol it may be obtained under the form of colourless, prismatic, acicular crystals.
Green, acicular crystals; deliquescent; soluble in alcohol, the flame of which it colours green.
By repeated solutions in alcohol it may be obtained under the form of white, silky, acicular crystals.
Spores of Bacidia fuscorubella to illustrate the several-celled, hyaline, acicular type.
Here I must once for all protest against the tendency of some opponents of Eozoon to confound these structures and the canal system of Eozoon with the acicular crystals, and dendritic or coralloidal forms, observed in some minerals.
The fragments are angular or rounded, small or large, and consist of bluish or reddish compact feldspathic matter, in which a few acicular crystals of feldspar can sometimes be seen.
Orbigny states that some of these crystals are acicular and more than even nine inches in length ("Voyage Geolog.

Sammetblende or przibramite is a variety, from Przibram in Bohemia, consisting of delicate acicular or capillary crystals arranged in radiating groups with a velvety surface and yellow colour.
In the same manner I treated the acicular leaves, and portions of the stem separately, both being previously cut up into small pieces, and from both I obtained phenol.
