Portraits of diseases of the skin.

Wilson's atlas, with 48 plates drawn and engraved by the medical artist, William Bagg, was the first English large folio atlas of dermatology in the style of similar folios issued in France by Alibert and Cazenave. The plates are classified under “General diseases,” “Syphilitic eruptions,” “Disordered chromatogenous function,” “Diseases of the sebiparous glands,” “Diseases of the hair follicles,” and “Specific diseases,” this last category containing illustrations of kelis (keloid), lupus and syphiloderma.
