Permit me, through your hands, to lay before the Society over which you so worthily preside, the enclosed papers, relating to a subject not foreign to their enquiries. I am sensible indeed there needs some apology for the many imperfections and errors that may be found therein; but, as I am persuaded, they will meet with the greatest degree of candor; I venture without any further hesitation to introduce this little essay, under your sanction, to the consideration of those, who I trust will both rectify the errors, and add many more curious observations to these imperfect hints.
