The Use of the preceding Table of number of days, will easily appear from the following examples.

Suppose the number of days between the first, or 10th, or 30th, &c. of January, and the 1st, or 10th or 30th, &c. of October, were required: Look in the column under January for October, and against that month you will find 273, which is the number of days between the said times; and so for the days between any other two months.

If the given days be different, it is only adding or subtracting their inequality to or from the tabular number.

How many days from the 6th of April to the 12th of January? From the 6th of April to the 6th of January is 275, and adding the 6 overplus days, it makes 281 days. And from the 5th of June to the 1st of February is 240 days.

Note. After February 31 (in leap years) increase each number with an unit or 1.

The use of the following Table, directing how to buy and sell by the hundred.

If you buy or sell any thing by the great hundred (112) and desire to know, by the , what the hundred is valued at, observe the following examples.

1. If you buy sugar at 63d. per , look for 6d. in the left hand column of the Table, against it in the second column, you will find £3 3s. which is the value of 1cwt. at that rate.

2. If 1cwt. (112) cost £9 4s. 4d. to know how much it is per , look £9 4s. 4d. in the fourth column, and against it in the next -left hand column, you will find Is. 74d. which is the price per 5.

Again, If you buy one hundred weight of goods for 91. 4s. 4d. and retail it at 1s. 94d. per tb, it comes at that rate to 101. 3s.; then take 91. 4s. 4d. from 101. 3s. and, by the remainder, you will find that you have gained 18s. 8d.

And in this manner you may, with ease, calculate any quantity by the following Table.
