corallin
(gcide) | Rosolic \Ro*sol"ic\, a. [Rose + carbolic.] (Chem.)
Pertaining to, or designating, a complex red dyestuff (called
rosolic acid) which is analogous to rosaniline and aurin. It
is produced by oxidizing a mixture of phenol and cresol, as a
dark red amorphous mass, C20H16O3, which forms weak salts
with bases, and stable ones with acids. Called also {methyl
aurin}, and, formerly, corallin.

various genera of Madreporaria, and to the hydroid
genus, Millepora. The red coral, used in jewelry, is

corals}, plume corals, and sea feathers are species
of Gorgoniacea, in which the axis is horny.

1. (Anat.) One of the hard, bony appendages which are borne
on the jaws, or on other bones in the walls of the mouth
or pharynx of most vertebrates, and which usually aid in
the prehension and mastication of food.
[1913 Webster]
Note: The hard parts of teeth are principally made up of
dentine, or ivory, and a very hard substance called
enamel. These are variously combined in different
animals. Each tooth consist of three parts, a crown, or
body, projecting above the gum, one or more fangs
imbedded in the jaw, and the neck, or intermediate
part. In some animals one or more of the teeth are
modified into tusks which project from the mouth, as in
both sexes of the elephant and of the walrus, and in
the male narwhal.
In adult man there are thirty-two teeth, composed
largely of dentine, but the crowns are covered with
enamel, and the fangs with a layer of bone called
cementum. Of the eight teeth on each half of each jaw,
the two in front are incisors, then come one canine,
cuspid, or dog tooth, two bicuspids, or false molars,
and three molars, or grinding teeth. The milk, or
temporary, teeth are only twenty in number, there being
two incisors, one canine, and two molars on each half
of each jaw. The last molars, or wisdom teeth, usually
appear long after the others, and occasionally do not
appear above the jaw at all.
