Extract

Notwithstanding the very large amount of leasehold property, which in the course of every year is bought and sold in this country, and notwithstanding the extensive transactions—of almost hourly occurrence—in the public market, in Government and other temporary Annuities, the subject of the rate of interest which any given purchase will yield the buyer is very imperfectly understood, even by those most deeply interested in the inquiry, unless they happen to be at the same time well versed in actuarial computations.

It is not unfrequently imagined by a buyer, that if he purchase a leasehold property or a temporary Annuity at a price corresponding with the value of an Annuity at a given rate of interest, (say 5 per cent.,) that he has made a purchase which will pay him 5 per cent., or which, in other words, will enable him to spend 5 per cent, per annum on his outlay, and at the same time replace his capital undiminished at the expiration of the term.

page 3 note * It is, however, due to Mr. Benwell to state, that his work above referred to distinctly treats the subjects now under consideration, but in a style so little happy, and so involved, that the merit of the actuary is apt to be overlooked in the obscurity of the writer. Mr. Benwell, moreover, computed some tables of a character similar to those appended to this Paper; two of the columns in Table of his little work are identical with Value columns 7 and 11 in the accompanying table; which table was, however, independently calculated, indeed, I never saw Mr. Benwell's book until the present Paper had been written for some weeks, and was actually in type.
