After the proper weights for each of the divisions are got ready, it will be easy to pick out such as may serve for the weight of any ley: For instance, No 16 and No 2, is 18 carats; or, 16, 4, and 2, is 22 carats; the boiling ley for English and foreign ashes.

The weights and measures which I have had occasion to mention, in the course of the preceding pages, are those used in the dispensaries, viz.

Wine Measure.

A gallon	$\scriptstyle {\left.{\begin{matrix}\ \\\\\ \ \end{matrix}}\right\}\,}$	contains	$\scriptstyle {\left\{{\begin{matrix}\ \\\\\ \ \end{matrix}}\right.}$	Eight pints.
The pint				Sixteen ounces.
The ounce				Eight drams.
The pound	$\scriptstyle {\left.{\begin{matrix}\ \\\\\ \\\ \ \end{matrix}}\right\}\,}$	contains	$\scriptstyle {\left\{{\begin{matrix}\ \\\\\ \\\ \ \end{matrix}}\right.}$	Twelve ounces.
The ounce				Eight drams.
The dram				Three scruples.
The scruple				Twenty grains.
