I think it is evident, therefore, that at present it is not safe either to affirm or deny that the two types may be phases only of one affection ; but until, and perhaps even after, we have discovered connecting links, it will conduce to clearness of conception to regard them as distinct types, and not to endeavour to weld all the symptoms of the two varieties into one comprehensive description. It may be safely assumed that the number of cases is too small to afford us a complete symptomology of these forms of disease, which can so clearly be traced to what French writers would term “ arthritism.” The microscopic examination of the portion of skin excised from Fig. 1.—a, Epidermis normal; b, Area of morbid process ; c, Coil glands and corium below, normal. The fibrous tissue between the cells is not visible with the low magni- fying power, x about 40. the knuckle showed that the epidermis was unchanged, except, perhaps, a slight thickening of the rete mucosum and elongation of the interpapillary processes in some parts. The seat of the morbid process was between the epidermis and the deep portion of the corium immediately adjacent to the coil-glands, all below these glands being normal. (Fig. I.) Within these limits was a fibro-cellular structure, which in great part replaced the normal fibres of the corium, such portions as were present taking the carmine stains more deeply than the new tissue.
