    SINCE the first Edition of the following Talks of Estimate calculation (into which some typographical errors had crept,) several superficial insinuations have been made, purporting, “ that my calculations of Profits appeared too wonderful to be true!” To all similar remarks I must leg leave to reply, that the annual course of our Planet round the Sun, and its diurnal rotations round its axis, have appeared, and do appear, still more wonderful than my tables of profithut they are nevertheless true. Whoever will not take the trouble to investigate the first prin¬ ciples of Astronomy, must remain as doubtful of its seeming wonders, as those who wish to partake of the great profits of my discovery, but who will not ascertain facts to remove their doubts. / only intreat the reader to attend to the official experi¬ ments, made at the Lyceum. They clearly proved, that two pecks of Coal produced the value of 6s. od. in products, du¬ ring the space of a few hours, which is at the rate of 231. 2s. per Chaldron. Now have the goodness to apply the simple rule of three, viz. If 1 Ch. contain 231 2s. how much contain 10,500,000 Ch. the annual average consumption of the Realm? Ans. £242,550,000 Deduct the cost of Coal and Carbonizing as per Table C.... 13,196,373 Net annual profits agreeable to the Official Experiments.... £229,353,627 But my estimate Tables will skew how many allowances, de¬ ductions, and undervaluations I h&ve made for contingencies, to reduce the above enormous Sum to near one half, viz. to 114,845,294/. Now if my readers will search for and col¬ lect all farther objections they can possibly imagine, I will abate Q-lOths of the last Sum, and the remaining tenth, must insure them an annual interest of 5/0/. for every 5l. Deposit, soon after the complete Establishmmi of this Company, according to my proposals. F. A. WINSQR.
