    one or more red cabbages to be cut up in strips, and boil- ing water poured on them, and a little dilute sulphuric acid (equal to % oz. of oil of vitriol to a large cabbage) to be added, and the whole kept hot for an hour or two in a copper or earthen vessel. It is then strained, the cabbage infused in a little more water and acid, and the mixed infusion evaporated to one third its first bulk, allowed to settle, and put into bottles. When required for use, the acid is neutralized by caustic potash or soda. Another plan is to dry the leaves at 120°; and when required for use to make a strong infusion, adding a drop of sulphuric acid, to neutralize the strained infusion with marble, filter, and add a little spirit, if required to be kept. Infusion or Tincture of Litmus. This is made as di- rected above for litmus paper. Or an ounce of powdered litmus may be triturated with 6 oz. of boiling water, di- gested near the fire for an hour, and mixed, when cool, with 2 oz. of spirit. Or digest 1 oz. of powdered litmus in a pint of proof spirit for 7 days. If required red, a few drops of acetic acid are added to either of these. The next day, decant the clear liquor. I)r. Pereira directs 1 part of litmus to 25 of water. When made very strong, it must be diluted when used. Tincture of Galls, Infusion of Galls, Sfc. Fresh pow- dered blue galls 1 oz., proof spirit 8 oz.; digest in a close vessel for a week, and filter. A watery infusion of galls may be made in the same proportion with boiling water for immediate use. Pettenkofer directs 1 oz. of pow- dered galls to be infused in 3 or 4 oz. of boiling water for several hours, and 2 oz. of salt added. After filtration, it retains its transparency and power of precipitating gela- tine for years. [This is used to detect iron, with the salts of which it produces a black colour; for gelatine, which it precipitates in brownish-white flocks; and several of the organic alkaloids.] Marsii’s Dahlia Test. Make a strong infusion of the petals of dark dahlias; strain, and add to every pint $ oz. of strong sulphuric acid; stir with a glass rod, and when cold, add to each pint 2 gr. of corrosive sublimate. Fil- ter through coarse cloth, and bottle. When required for
