The following rules will be found of great assistance in writing, because they relate to a class of words about the spelling of which doubt and hesita tion are frequently felt: -

1664. All words of one syllable ending in I, with a single vowel before it, have double I at the close: as, mill, sell.

1665. All words of one syllable ending in I, with a double vowel before it, have one I only at the close: as, mail, sail.

1666. Words of one syllable ending in I, when compounded, retain but one l each; as, fulfil, skilful.

1667. Words of more than one syllable ending in I, have one I only at the close; as, delightful, faithful; except befall, downfall, recall, unwell, etc.

1668. All derivations from words ending in I have one I only; as equality, from equal; fulness, from full; except they end in er or ly; as mill, miller; full, fully.

1669. All participles in ing from verbs ending in e, lose the e final; as have, having; amuse, amusing; unless they come from verbs ending in double e, and then they retain both; as, see, seeing; agree, agreeing.

1670. All adverbs in ly and nouns in ment retain the e final of the primi-fives; as, brave, bravely; refine, refine-ment; except acknowledgment and judgment.

1671. All derivations from words ending in er retain the e before the r as, refer, reference; except hindrance, from hinder; remembrance, from, remember; disastrous, from disaster; -onstrous, from monster; wondrous, from wonder; cumbrous, from cumber, &C.

1672. Compound words, if both end not in I, retain their primitive parts entire; as, millstone, changeable, race-less; except always, also, deplorable, although, almost, admirable, &c

1673. All one-syllables ending in a Consonant, with a single vowel before it, double that consonant in derivatives; as sin, sinner; ship, shipping; big, bigger; glad. gladder, etc.

1674. One-syllables ending in a consonant, with a double vowel before it, do not double the consonant in derivatives; as, sleep, sleepy; troop, trooper.

1675. All words of more than one syllable ending in a single consonant, preceded by a single vowel, and accented on the last syllable, double that consonant in derivatives; as, commit, committee, compel, compelled; appal, appalling; distil, distiller.

1676. Nouns of one syllable ending in y, preceded by a consonant, change y into ies in the plural; and verbs ending in y, preceded by a consonant, change y into ies in the third person singular of the present tense, and into ied in the past tense and past participle: as, fly, flies; I apply, he applies; we reply, we replied or have replied. If the y be preceded by a vowel, this rule is not applicable; as, key, keys; I play, he plays; we have enjoyed ourselves.

1677. Compound words whose primitives end in y change y into i; as beau-it/, beautiful; lovely, loveliness.
