About This Book
Leather Binding on Spine and Corners with Golden leaf printing on spine. This book is printed in black & white, Sewing binding for longer life, where the book block is actually sewn (smythe sewn/section sewn) with thread before binding which results in a more durable type of binding. Reprinted in 2022 with the help of original edition published long back 1905. As this book is reprinted from a very old book, there could be some missing or flawed pages. Resized as per current standards. We expect that you will understand our compulsion with such books. If it is multi volume set, then it is only ...
