Thanks for the link, I have come across it before but appear to have lost it, so I've added it to my favourite places once again. I'm lucky in so far as I own a copy of Harold Ward's book, which in parts resembles an abridged version of Mrs Grieve's 'Modern Herbal'. I have been trying to track down a copy of William Fox's book for some time, but the prices thus far have been silly. I'll try to read the book online, but like you I prefer to physically hold the book in my hands.
I do still owe you a list of the recent 'old' herb books I've added to my collection, last weeks bounty comprised of:-
The Art of Natural Healing by Dr Carl Q. Schilling  and American chap, the book includes recipes that contain listerine of all things, apparently the mouthwash has been around in the states since around 1879, but originally it wasn't a mouthwash but an antiseptic for surgeons, it wasn't marketed publicly as a mouthwash until 1914, but I digress.
I have parts 1 - 8 of Pointers To The Common Remedies by Dr Margaret L Tyler  a series of booklets on homeopathy, there were apparently 9 parts, no idea what the last part was called so if anybody knows to help my search to complete the set I'd appreciate it?
Herbal Teas For Health And Pleasure by Donald Law .
The Roots Of Health by Leon Petulengro , Leon being the son of Gipsy Petulengro the famed Gipsy that had a BBC radio show about romany remedies and recipes in the 1930's.
The Physick Garden by Edith Grey Wheelwright [first published 1934 but mine is the 1939 version]. The delightful thing about this book aside from all the wonderful information within, is the the book is dedicated to Beatrix Potter, seems that the author was also a fan of Mrs Grieve as well More on the last two books in another post later today.
