Does anyone know this book "The Dogs of Scotland" by Thompson Gray, published in 1891 by James P. Mathew in Dundee? It's supposed to have a chapter on deerhounds. I was wondering if it's worth trying to get hold of a copy.

Depending on your interest - yes it is worth reading or getting.
One of the better chapters on the breed - also, from a Scottish perspective.
If you can't find or purchase the book, you could try the KC Library, and see if you are able to purchase a photocopy of the chapter.
Unfortunately the book is not (yet) on the Internet Archive, an invaluable source for old, out of copyright books. Richard

Thanks! I'll get hold of a copy.
