Basyle is the name given by Graham, the eminent chemist, to a simple or compound sub- stance which can unite with oxygen to produce a Base (q.v.). Thus, all the metals are examples of simple basyles, and ammonium, , ethyl, , methyl, , &c. represent compound basyles. In recent years the term has fallen into disuse, radicals or compound radicals being used instead to designate the compound basyles.
