What reading level is The Principles of Leather Manufacture book?
To quickly assess the difficulty of the text, read a short excerpt:
Gelatine swells in very dilute acids to a much larger extent than in water. In weak acids this swelling increases with the concentration of acid till finally solution takes place, but with strong acids the swelling reaches a maximum at very low dilutions, and subsequently diminishes in a curve of hyperbolic character till the jeUy dissolves without further swelling, which limits the possible range of experiment. If, however, a neutral salt of the acid be added, the dehydration may be carried wi...th strong acids to a point at which the gelatine forms a solid and horny mass.
With weak acids and their salts the effect is less marked, but quite obvious. If, however, a weak acid is used with large excess of a salt of a strong acid the gelatine behaves as if the strong acid only was present, while gelatine swollen with a strong acid and treated with the salt of a weak one naturally behaves as if the weak acid had been used.
In all cases the acid absorbed by the swelling gelatine is in excess of that due to the absorbed solution, and this excess is in any one series of experiments of an approximately constant amount over a wide range of concentration of the acid or acid and salt solution ; while under no conditions does it pass a maximum of about 1-25 mgr.-mols.
