'A System for the Construction of Crystal Models' by John Gorham was published by E and F N Spon in London in 1888. It explains how models of crystal forms, essentially polyhedra, can be created by weaving together several folded strips.

My thanks for Tung Ken Lam / Michel Grand for calling this book to me attention.

A full copy of the work can be accessed online here.

Further details will be added when time allows.
