37. BLACK INK WITHOUT SEDIMENT
This ink is not injured by frost—is a beautiful article, and only costs 5 cents. per gallon, and is sold for from $1 to $3. Take 1 lb. logwood, 1 gallon soft water, simmer in an iron vessel for one hour, then dissolve in a little hot water 24 grains bychromate of potash, and 12 grains prussiate of potash, and stir into the liquid while over the fire, then take it off and strain it through fine cloth. This ink is a jet black flows freely from the pen and will stand the test of oexylic acid.

1 inch of the stick of the nitrate of silver dissolved in a little water, and stirred into each gallon of the above, makes first rate indelible ink for cloth. Judge what indelible ink costs.
39. INDELIBLE INK
Nitrate of silver 1-1/2 oz., dissolved in liquor ammonia fortisine 5-1/2 oz., orchil for colouring 3/4 oz., gum mucilage 12 oz., mix the two latter, then mix them with the two former, and it is ready to use.
40. WRITING FLUID OR BLACK COPYING INK
Take two gallons of rain water and put into it gum arabic 1/4 lb., brown sugar 1/4 lb., clean copperas 1/4 lb., powdered nut galls 3/4 lb., mix and shake occasionally for ten days and strain. If needed sooner, let it stand in an iron kettle until the strength is obtained. This ink can be depended on for deeds or records, which you may want someone to read hundreds of years to come. Oexylic acid 1/4 oz., was formerly put in, but as it destroys the steel pens, and does just as well without it—it is now never used.
