PRINTED FOR THE AUTHOR, Ibid. BY S. COUCHMAN, No. 10, THROGMORTON-STREET; PREFACE. T has been well remarked, that "it is every man's duty who comes into the world, to use his beft endeavours, however infignificant, to leave it as much wifer, and as much better as he can. If this obfervation inculcates a general duty, it applies, with peculiar force, to perfons engaged in inftruction by their profeffion. Viewing the admonition in this obligatory light, I conftantly endeavour to render the several parts of my professional occupation as fubfervient to the great end it aims to promote, as their nature will admit. Upon this plan most of the following questions have been compofed, which, with feveral others of a similar kind, but on a more confined scale, have been long dif tributed among my own scholars; and I have often had the fatisfaction of finding them fignally inftrumental in infpiring a defire of more extenfive and circumftantial information.

But other inftructors, of more animation and zeal, will occafionally require minute accounts of the hiftorical, geographical, chronological, and other subjects, which had before ferved as arithmetical themes. They will, perhaps, with the author, deem the time when the scholars are affembled in claffes to repeat their tables (which, I fhall take for granted, is always once a week) the best suited for promoting general emulation, and diffeminating the defired A knowledge |
