» Syrup is a solution of Sucrose in Purified Water. It contains a preservative unless it is used when freshly prepared.

Syrup may be prepared by the use of boiling water or, preferably, without heat, by the following process. Place the Sucrose in a suitable percolator, the neck of which is nearly filled with loosely packed cotton, moistened after packing with a few drops of water. Pour carefully about 450 mL of Purified Water upon the Sucrose, and regulate the outflow to a steady drip of percolate. Return the percolate, if necessary, until all of the Sucrose has dissolved. Then wash the inside of the percolator and the cotton with sufficient Purified Water to bring the volume of the percolate to 1000 mL, and mix.
