Take one gallon of this prepared shellac,four gallons linseed-oil, ten ounces balsam of fir, four pounds White-lead to fifteen pounds of (No specimens.)

Hour of emery, or enough to thicken to the consistency of thick paint. Stir Well together and use with a brush.

For colors I use red, green, or any desired color in the common Way.

I claim- Aliquid slate-paint compounded of common gum-shellac, water, and potash, in the quantities and manner described, in combination with linseed-oil, balsam of fir, white lead, and flour of emery, in quantities named, substantially as shown, and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
