The book we worked with was called “the way to Health” by Tryon. It was a very small book, about pocket size. Its rough dimensions were roughly 20 x 12 x 4 cm and weighted about 3.5 lbs. The library guy said it was an octavo, a total of 520 pages so that should mean 65 leaves folded 8 times. The book was most probably in its original leather binding along with the reconstruction of the backbone of the book. It had that undistinguishable old book smell.
