OBS. 15.--The second clause of Murray's or Walker's 5th Rule for spelling,
gives only a single _l_ to each of the derivatives above named.[124] But it
also treats in like manner many hundreds of words in which the _l_ must
certainly be doubled. And, as neither "the Compiler," nor any of his
copiers, have paid any regard to their own principle, neither their
doctrine nor their practice can be of much weight either way. Yet it is
important to know to what words the rule is, or is not, applicable. In
considering this vexatious question about the duplication of _l_, I was at
first inclined to admit that, whenever final _l_ has become single in
English by dropping the second _l_ of a foreign root, the word shall
resume the _ll_ in all derivatives formed from it by adding a termination
beginning with a vowel; as, _beryllus, beryl, berylline_. This would, of
course, double the _l_ in nearly all the derivatives from _metal, medal_,
&c. But what says Custom? She constantly doubles the _l_ in most of them;
but wavers in respect to some, and in a few will have it single. Hence the
difficulty of drawing a line by which we may abide without censure.
_Pu'pillage_ and _pu'pillary_, with _ll_, are according to _Walker's
Rhyming Dictionary_; but Johnson spells them _pu'pilage_ and _pu'pilary_,
with single _l_; and Walker, in his Pronouncing Dictionary, has _pupilage_
with one _l_, and _pupillary_ with two. Again: both Johnson's and the
Pronouncing Dictionary, give us _medallist_ and _metallist_ with _ll_, and
are sustained by Webster and others; but Walker, in his Rhyming Dictionary,
writes them _medalist_ and _metalist_, with single _l_, like _dialist,
formalist, cabalist, herbalist_, and twenty other such words. Further:
Webster doubles the _l_ in all the derivatives of _metal, medal, coral,
axil, argil_, and _papil_; but writes it single in all those of _crystal,
cavil, pupil_, and _tranquil_--except _tranquillity_.

OBS. 16.--Dr. Webster also attempts, or pretends, to put in practice the
hasty proposition
