The British Journal of Medicine described the 1856 edition (ours is from 1859) of this work as follows: “This is a pretty little book, containing all that it is needful for the amateur doctor to know concerning the external use of arnica, calendula, cantharides, ledum, ruta and rhus toxicodendhron.  It is illustrated with very pretty coloured representations of the plants above named, which however, as Mr. Primrose’s critic would have said, ‘might have been better if the artist had taken more pains.’”  Maybe so, but it is undeniably a very sweet little book, and the perfect size to slip into your pocket!
