To quickly assess the difficulty of the text, read a short excerpt:
Iodide of potassium in solution.
Into either of these I dip a strip of cloth or thread, which is kept properly moistened. All these give a black mark upon the cloth, thread, or other material under the action of elec- tricity.
Class B. A class of salts which color the cloth, paper, thread, or other material, and are bleached by the action of electricity.
1st. Iodide of tin in solution.
2d. Iodine dissolved in alcohol.
Into either of these I dip a strip of cloth, paper, thread, or other material... ; and if in solution second, I also dip them into a solution of sulphate of soda, the cloth or other material, in these cases, becomes of a purple color more or less dark. The electricity in these cases, when a metallic point or type is pressed upon, or comes in contact with the moist cloth or other material, bleaches it, and leaves the point or the type impressed in white characters upon the material.
Class C. A class of salts that produce a mark upon metal, through the intervening cloth or other material, and not upon the material, under the action of electricity.
