This was the most influential textbook of dermatology of the 19th century, and the work which conveyed Willan’s system to most of the medical world. Included in the book was material by Willan which remained unpublished from his unfinished On cutaneous diseases. The Synopsis also “contained material original to Bateman himself…and it also provided insights into the origins of the morphologic system and an appreciation of its limitations not to be found in the work it was designed to complete” (Crissey & Parish). Description of lichen urticatus appears on p. 13.
