Bmine the beft way of remitting money from

abroad, with advantage, which is performed by Conjoined Proportion, thus.

Admit a Merchant hath effects at Leghorn to the amount of 2740 dollars, which he can remit by way of Lifoon at 900 rees per dollar and thence to London at 65. 6d. 1. per mitree, or by way of Lyons at 6 livres and per dollar, and thence to London at 33d. per crown, now it is required to arbitrate, thefe Exchanges, (i. e.) to choose that which is moft advantageous?

Hence appears the neceflity and advantage of an extenfive correfpondence in thefe kind of reinittances.
