Tun measured ounces of simple syrup should weigh nearly thirteen ounces and one-third, representing the sp. g. 1-330. In the formulas for the Syrups of the British Pharmacopoeia some of them are directed to be made to a given weight, and the specific gravity is also stated. It can be easily ascertained what any of these weights would measure, by dividing tho weight by the specific gravity ; thus Syrupus Aurantii Floris is directed to weigh 72 oz., and the specific gravity to be 1-330, then 72-000 — 1-330 = 54, or 54 ounces by measure.
