These are of different capacities, to measure 8 ounces, 2 ounces, 1 ounce and 1 drachm respectively ; the scale of each being graduated to represent the aliquot parts of their respective capacities.

No. 1 represents an 8-ounce measure; the figures on the left of the graduated scale denote ounces, and those on the right, drachms; the first ounce being divided into quarters of 2 drachms each. No. 2 is a 2-ounce measure, the first half-ounce being divided into drachms. Nos. 3 and 4 are 1 ounce and 1 drachm measures respectively; the former is graduated in drachms, the first of which is divided into halves; the latter is marked in divisions of 5 minims each.
