TYM´PANIC (_bone_), _a._ for _n._ Same as OS QUADRATUM (which see).
TYM´PANUM, _n._ Ear-drum. Also, the naked inflatable air-sacs on the
sides of the neck of grouse, an enlargement of the ordinary cervical
reservoirs of air which communicate with the bronchi.
TYPE, _n._ Way; plan; mode. Also, sign or symbol. The _type_, or
_typical form_, of a group is that which exhibits a given set of
characters most perfectly. But the _type_ of a genus is usually the
species, if any, from which the generic characters were especially drawn
up, without reference to such qualification; while, furthermore, the
_type_ of a species, in current acceptation, is merely the specimen from
which the species was originally described, even though it may very
inadequately represent such species.
TYP´ICAL, _a._ Of most usual structure; adhering strictly to a given
plan of structure. (But compare TYPE.)
