When my first case of Ptyalism, rupoid erup- tions, stomatitis phageclenica, and mercurial erythism, in a patient wearing one of these plates, was observed by me in 1862, I satisfied myself that the colouring matter in that instance was vermilion. When another case occurred in London, in 1864, I obtained a number of samples of pink and red rubbers, some by purchase in various quarters, whilst others were procured for me by Dr. Martin H.
