This process is called straining, though a kind of filtration. In-fusions, decoctions, syrups, fixed oils, and melted ointments, are sub-jected to it in order to separate foreign ingredients. They passthrough the strainer with much greater facility when quite hot,though in the case of the fixed oils a clearer product is obtained byconducting the operation in the cold, and by using several thick-nesses of the flannel, or by employing Canton flannel with the napon the inside. Coarse linen is sometimes better than flannel, espe-cially when considerable pressure is to be employed, as in extract-ing the juice from the pulp in making fruit syrups. Figs. 79 and 80 represent an apparatus I have been using forsome time past for straining syrup
