Read in the Wunder reader — free«Table of Drops.»—Used in estimating the amount of a flavoring extract necessary to flavor a gallon of syrup. Based on the assumption of 450 drops being equal to 1 ounce.
One drop of extract to an ounce of syrup is equal to 2 drachms to a gallon.
Two drops of extract to an ounce of syrup are equal to 4 1/2 drachms to a gallon.
Three drops of extract to an ounce of syrup are equal to 6 1/2 drachms to a gallon.
Four drops of extract to an ounce of syrup are equal to 1 ounce and 1 drachm to a gallon.
Five drops of extract to an ounce of syrup are equal to 1 ounce and 3 1/8 drachms to a gallon.
Six drops of extract to an ounce of syrup are equal to 1 ounce and 5 1/2 drachms to a gallon.
Seven drops of extract to an ounce of syrup are equal to 2 ounces to the gallon.
Eight drops of extract to an ounce of syrup are equal to 2 ounces and 2 1/2 drachms to a gallon.
Nine drops of extract to an ounce of syrup are equal to 2 ounces and 4 1/2 drachms to a gallon.
Ten drops of extract to an ounce of syrup are equal to 2 ounces and 6 3/4 drachms to a gallon.
Twelve drops of extract to an ounce of syrup are equal to 3 ounces and 3 1/4 drachms to a gallon.
Fourteen drops of extract to an ounce of syrup are equal to 4 ounces to a gallon.
Sixteen drops of extract to an ounce of syrup are equal to 4 ounces and 4 1/8 drachms to a gallon.
Eighteen drops of extract to an ounce of syrup are equal to 5 ounces and 1 drachm to a gallon.
NOTE.—The estimate 450 drops to the ounce, while accurate and reliable enough in this particular relation, must not be relied upon for very exact purposes, in which, as has frequently been demonstrated, the drop varies within a very wide range, according to the nature of the liquid, its consistency, specific gravity, temperature; the size and shape of the aperture from which it is allowed to escape, etc.
«Fluid Measure.—U. S. Standard, or Wine Measure.»—Sixty minims are equal to 1 fluidrachm.
Eight fluidrachms are equal to 1 fluidounce.
Sixteen fluidounces are equal to 1 pint.
Two pints are equal to 1 quart.
Four quarts are equal to 1 gallon.
One pint of distilled water weighs about 1 pound.
«Percentage Solutions.»—To prepare the following approximately correct solutions, dissolve the amount of medicament indicated in sufficient water to make one imperial pint.
For 1/50 per cent, or 1 in 5,000 solution, use 1 3/4 grains of the medicament.
For 1/20 per cent, or 1 in 2,000 solution, use 4 3/8 grains of the medicament.
For 1/10 per cent, or 1 in 1,000 solution, use 8 3/4 grains of the medicament.
For 1/4 per cent, or 1 in 400 solution, use 21 7/8 grains of the medicament.
For 1/2 per cent, or 1 in 200 solution, use 43 3/4 grains of the medicament.
