Note. If the reader is not versed in Decimals, let him divide the milreas and reas as 1 whole number and cut off the three last figures from the sum (which divides it by 1000,) the figures cut off are the remainder, viz. so many thousandths of 11. of which remainder the value may be found.

SECT. VII.

Of Exchange between England and Italy.

England exchanges on Leghorn for the dollars of 6 livres, and gives pence sterling for the same, they reckon 12 deniers to the soldi, and 2 soldi to the dollar.

On Genoa for the piastre of 5 livres, they keep accounts in livres, sols, and deniers, 12 deniers 1 sol, and 20 sols 1 livre.

On Venice for the ducat of 24 gross banco for pence sterling, accounts are kept in livres, sols, and gross current, 12 gross 1 sol, 20 sols=1 livre.

The bank and bankers keep their accounts in livres, sols and grosses banco; livre 10 ducats bank, or 12 current, so that current money is of less value than bank money by 20 cent.

From which it is easy to conceive that these exchanges are calculated on the like principles as the French, which having explained, it doth not appear necessary to enlarge farther on this head.

PART II.

ARBITRATIONS OF EXCHANGE.

UNDER the head of Arbitrations of Exchanges are com

prehended first the calculation of the proportional exchange of two places by means of one or more interme diate exchanges given, and secondly, having two or more different routes of exchange, to compute which is more gainful, or whether it is more advantageous to remit money or bills, or to draw or order a remittance. et contru.

Since Ireland draws all its foreign demands by London, there is always one intermediate exchange wherely to compute the value of any foreign sum in Irish money according to the present rates of exchange, wherefore we be gin with this problem.

Examples.

1. How much will 1001. Flemish amount to Irish currency, exchange between London and Amsterdam being 33s. 4d. l. and between London and Dublin 8 ' cent. advance.

But in this case where a comparison is made between one rate and a second, between that second and a third, between the third and a fourth, &c. instead of stating each comparison Rule of Three, there is a more ready and contracted way called the Rule of Conjunction, for which this is the Rule.

1. Place the antecedents on the left, and the consequents on the right hand.

2. The first antecedent and last consequent must be of one name or species; so must the first consequent and se, cond antecedent. the second consequent and third antecedent, which order must be continued through the whole.

3. The terms being thus disposed, multiply all the antecedents for a divisor, and all the consequents for a dividend, if the place of an antecedent be blank: and all the consequents for a divisor, and all the antecedents for a dividend, if the place of a consequent be blank.

III. If any term have a fraction annexed, multiply the integral part by the denominator of the fraction (adding iu the numerator) and place the result in the room of the inixt number and the denominator on the opposite side below.
