ll have _fillipping, gossipping_, and
_worshipping_, to be needful exceptions also.

OBS. 12.--Final _s_ sometimes occurs single, as in _alas, atlas, bias_; and
especially in Latin words, as _virus, impetus_; and when it is added to
form plurals, as _verse, verses_: but this letter, too, is generally
doubled at the end of primitive words of more than one syllable; as in
_carcass, compass, cuirass, harass, trespass, embarrass_. On the contrary,
the other consonants are seldom doubled, except when they come under Rule
3d. The letter _p_, however, is commonly doubled, in some words, even when
it forms a needless exception to Rule 4th; as in the derivatives from
_fillip, gossip_, and perhaps also _worship_. This letter, too, was very
frequently doubled in Greek; whence we have, from the name of Philip of
Macedon, the words _Philippic_ and _Philippize_, which, if spelled
according to our rule for such derivatives, would, like _galloped_ and
_galloper, siruped_ and _sirupy_, have but one _p_. We find them so written
in some late dictionaries. But if _fillipped, gossipped_, and _worshipped_,
with the other derivatives from the same roots, are just and necessary
exceptions to Rule 4th, (which I do not admit,) so are these; and for a
much stronger reason, as the classical scholar will think. In our language,
or in words purely English, the letters _h, i, j, k, q, v, w, x_, and _y_,
are, properly speaking, never doubled. Yet, in the forming of _compounds_,
it may possibly happen, that two Aitches, two Kays, or even two Double-ues
or Wies, shall come together; as in _withhold, brickkiln, slowwoorm,
bayyarn_.

OBS. 13.--There are some words--as those which come from _metal, medal,
coral, crystal, argil, axil, cavil, tranquil, pupil, papil_--in which the
classical scholar is apt to violate the analogy of English derivation, by
doubling the letter _l_, because he remembers the _ll_ of their foreign
roots, or their foreign correspondents. But let him also remember, that, if
a knowledge of etymology may be shown by spelling metallic, metalliferous,
metallography, metallurgic, metallurgist, metallurgy, medallic, medallion,
crystallize, crystalline, argillous, argillaceous, axillar, axillary,
cavillous, cavillation, papillate, papillous, papillary, tranquillity, and
pupillary, with double _l_, ignorance of it must needs be implied in
spelling metaline, metalist, metaloid, metaloidal, medalist, coralaceous,
coraline, coralite, coralinite,
