    6. To employ, when possible, water which had already been distilled from oflf the same substances, and had thus become saturated with oil. 7. For oils naturally fluid, to cool the liquid in the refrigeratory frequently; but to retain it at 80° to 90° for those oils which easily become solid. After the distillation, the oil should be separated from the water; for this pur- pose, several ingenious instruments have been devised, a few of which are repre- sented in figures 28 to 33 inclusive. Fio. 30. Fio. 31. Fio. 32. Fio. 33. Separatinq-Fonnel. Separator. Separator. Fig. 30. The ordinary separating funnel, having a perforated ground-glass stopper. Fig. 31 is a vessel for separating ether, or other volatile liquids from heavier ones. Fig. 32 answers very well when the quantity of the fluids is very small. By inclining It, the heavier liquid escapes by the orifice a. Fig. 33 is a separator for either heavy or light oils. The former can he drawn off by the orifice of the tube 6; the latter by the tubule d e. The following table, from Christison’s Dispensatory, showing the proportion of volatile oil obtained from the chief medicinal vegetable substances, according to the most recent experiments, will be found useful. The data are chiefly extracted oj: calculated from experiments by M. Raybaud in the Journal de Phar^acie, xx.— by Dr. Martins in Repertorium fur die Pharmacie, xxxix.—by Dr.’Bley in the same work, xlviii.—by M. Dann and by M. Voelter in the same work, Iv.;—and a few have been added from experiments of Dr. Christison himself. The numbers repre- sent the number of ounces obtained from 100 pounds avoirdupois. The letters before the figures refer to the authority for each. Amyg-dalus communis. Bitter almond .... Ainygdalus communis. Bitter almond Amygdalus communis.
