An old friend, long since gone to ‘kingdom come,’ began the study of Persian at rather an advanced age; which caused many to rally him on the new turn he had taken. He, however, persevered, and, in the course of two years, made himself more than commonly proficient. The explanation he gave, regarding the plan he had laid down, was such as convinced me, that any person, with a tolerable memory, may, in a moderate time, acquire any regular language. His mode was, for the first month never to retire to bed until he had learned twenty words perfectly by heart, so as to explain them with promptitude, however catechized: after that first month, he was master of no less than six hundred words. During the next month, finding that former acquirements greatly facilitated his progress, he made a point of gaining twenty-five words daily; therefore that month gave him seven hundred and fifty words; which, added to the six hundred of the preceding, made a total of thirteen hundred and fifty. In this way he added five words every month, until he found, that, by aid of derivations and compounds, he was well grounded in the language. His computation was, that, as few languages contain more than forty thousand words in common use, when ever he should be able to learn fifty words daily, he might, to use his own terms, ‘make the language fall before him in two years.’ This is an arithmetical demonstration of the powers annexed to persevering regularity, and ought to induce every youth, for that is the season for acquirements, to adopt such a system as should insure the great object in view. So steady a mode of carrying on a pursuit, cannot, however, be expected in young folks, many of whom have just escaped from the trammels of parental vigilance; and who, having passed so many years at their studies, rarely feel much disposition to prolong academic labors; while, at the same time, the pleasures of society are open to their participation. Still, I feel a hope that this volume may prove intrinsically beneficial to a large portion, by pointing out the means whereby preferment may be obtained, and by shewing with what facility the foundation may be laid for a most superb superstructure.
