A plain, rational essay on English grammar : the main object of which is to point out a plain, rational and permanent standard of pronunciation. : To which is given, a gamut or key, still more simple, plain and easy than that given to music, pointing out the quantity and quality of every syllable and word, according to the present mode among polite scholars. ... This plan, hitherto unattempted, is respectfully inscribed to British and American ladies and gentlemen, whose generous criticism and assistance is humbly requested by their devoted humble servants, Dunc'an Mack'intosh and his two daughters. Martini'co, the 4th of July, 1797.
