Leathery Skins and Other Things
This is an intermediate textbook of the kind handed out to second year university students. Leafing through it reveals that it's aimed at are looking to teach themselves the basic of tanning. It has many diagrams and densely packed passages of text. You'd need to have a reasonable amount of knowledge before you could really hope to make much of a dent in it.
It's a mess of diagrams and large blocks of explanatory text covering the application of tanning procedures to a skin. You'd need to study the book closely in order to get any real benefit from it.
It looks like you could use it to practise tanning skins.
