1. Brande's. Bruised Aleppo galls 6 oz., soft water 6 pints; boil together, add 4 oz. of sulphate of iron and 4 oz. of gum arabic. Put the whole in a bottle, and keep it in a warm place, shaking it occasionally. In 2 months pour it off into glass bottles; and add to each pint a grain of corrosive sublimate, or 3 or 4 drops of creasote.

2. Dr. Wollaston's, Galls 1 oz., gum 1/2 oz., cloves

1/2 dr., sulphate of iron 1/2 oz., water 8 oz. Digest with frequent shaking, till it has sufficient colour. A good durable ink, and will bear diluting.

3. Prerogative Court Ink. Galls 16 oz., gum 6 oz., alum 2 oz., sulphate of iron 7 oz., kino 3 oz., logwood in powder

4 oz., water 8 lbs. - Gray.

4. Dr. Ure's Ink. For 12 gallons of ink take 12 lbs. of bruised galls, 5 lbs. of gum Senegal, 5 lbs. of green sulphate of iron, and. 12 gallons of rain water. Boil the galls in a copper with 9 gallons of water for 3 hours, adding fresh water to replace what is lost by evaporation. Let the decoction settle, and draw off the clear liquor; add to it a strained solution of the gum; dissolve also the sulphate of iron separately, and mix the whole. Instead of boiling the galls, they may be macerated in a portion of hot water for 12 hours, then put into a percolator, and the rest of the water passed through it.

5. Anti-corrosive Ink. Aleppo galls 10 lbs., logwood 5 lbs., pomegranate-peel 2 1/2 lbs., cloves 2 1/2 oz., soft water 8 gallons. Let the whole boil gently for an hour or two, then cover the copper and leave it for 12 or 14 hours, stirring it now and then. Strain off the decoction and add 2 gallons more water to the ingredients; simmer gently for an hour, and strain. Mix the liquors, and let them settle; draw off the clear liquid from the dregs; dissolve in a portion of it 2 1/2 lbs. of gum arabic and 1/2 lb. of sugar candy; and in another portion 2 1/2 lbs. of green sulphate of iron. Strain both solutions, and mix the whole together; then add 1 oz. of calcined borax, and 1/4 oz. of creasote dissolved in 1/4 pint of spirit of wine. [Dr. Hare recommends an ink free from acid, to be made with galls and " finery-cinder;" but we are not sure what is intended by this name.]

6. Ribaucourt's Ink. Galls 1 lb., logwood 1/2 lb., gum 6 oz., sulphate of iron 1/2 lb., sulphate of copper 2 oz., sugar 2 oz., water 12 lbs. (or 5 quarts). This has the disadvantage of corroding the steel pens and the penknives with which it conies in contact.

7. Galls 3 oz., sulphate of iron 1 oz., logwood 1/2 oz., gum 1/2 oz., ale a quart. Let it stand in a loosely corked bottle in a warm place, for a week or more, shaking it daily.

8. Boil 4 oz. of logwood for an hour in 6 quarts of water; adding boiling water as it evaporates: then add 16 oz. of blue galls coarsely bruised, 4 oz. of dry sulphate of iron (i. e. heated till it becomes whitish and pulverulent), 3 oz.' of brown sugar, 6 oz. of gum arabic, and 1/4 oz. acetate of copper ground with a little of the decoction. Keep the whole in a bottle uncorked for a fortnight, shaking it twice a day.

9. Reade's Patent. This differs from common black ink, in containing a portion of soluble Prussian blue.

10. Chrome Ink. Extract of logwood 1/2 oz., gum 1/4 oz., water a pint. Dissolve also in 12 oz. of water, 1/4 oz. of yellow chromate of potash (or 1/4 oz. each of bichromate and bicarbonate of potash); and mix the two solutions. The ink is ready for immediate use.

11. Dr. Lewis's Writing Ink. Powdered sulphate of iron 1 oz., powdered logwood 1 oz., powdered galls 3 oz., gum arabic 1 oz., white wine or vinegar 1 quart.

12. Berzelius recommends a solution of vanadiate of ammonia in infusion of galls. Dr. Ure states that this forms the most perfect ink that can be desired; but the scarcity and high price of the vanadiate prevents its use.

13. Runge's Black Writing Fluid. Boil logwood 22 lbs., in enough water to yield 14 gallons of decoction. To 1000 parts of this decoction, when cold, add 1 part of chromate of potash. The mixture is to be well stirred. The proportions are to be carefully observed, and the yellow chromate, not the bichromate, employed. (This ink is said to possess some great advantages; to adhere strongly to paper, so that it can neither be washed off by water, nor even altered by weak acids; to form no deposit; and not to be in the least acted upon by steel pens.) Steel pens should be washed in an alkaline solution before being used with this ink. On exposure to the air, rapid decomposition of this fluid sometimes takes place. This may be prevented by adding a little carbonate of soda to the fluid.

14. Alizarine Ink. Leonhardi. Digest 24 parts Aleppo galls with 3 parts of Dutch madder and 120 warm water. Filter. Mix 1.2 parts solution of indigo, 5.2 of sulphate of iron, and 2 parts crude acetate of iron solution. This ink contains no gum, and cannot get mouldy; the tannate of iron is prevented from separating by the sulphate of indigo. Alizarine ink may be evaporated to dryness and formed into cakes; 1 part with six of hot water will then form an excellent writing fluid.

Packers' Marking Ink is merely the dregs of black ink, for marking parcels with a brush.
