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.
|A gallon||contains||Twelve ounces.|
|The ounce||Eight drams.|
|The dram||Three scruples.|
|The scruple||Twenty grains.|
