Fig. 1.-PSORIASIS guttata s a form of the scaly tetter most nearly allied to the Lepra, and characterized by small, distinct patches of thin scales, with little or no inflammation round them, and without the regular circular figure, or the elevated border of Lepra. Their circumference is often angular, and sometimes slightly serpentine. Fig. 2.-PSORIASIS diffusa ; which consists of irregular, rough, and reddish patches, of various sizes, interspersed with chops and scales, the surface of which is exceedingly tender and irritable. In this variety, the patches are separate ; but they are apt to expand till they become confluent. "In 1814 Bateman acquired the copyright to the engravings in the Willan treatise. He arranged to have the plates refurbished,".

Delineations of Cutaneous Diseases, 13. - London, Henry G. Bohn, 1815 (1849), 1 hand colored engraved plate, 246 x 242 mm, added a descriptive text leaf. Fig. 1.-- PSORIASIS diffusa ; a variety of the eruption, not figured by Dr. Willan, which occurs almost exclusively in young subjects, affecting the whole surface of the body, and producing a considerable degree of itching and irritation, but without any material derangement of the health. The scales and patches are both more numerous and more minute on the trunk than on the extremities. This drawing was taken from a boy about nine years of age. Fig. 2.-PSORIASIS inveterata ; the most extensive and severe form of the disease, " is characterized by an almost universal scaliness, and a harsh, dry, thickened state of the skin it begins in separate patches on the extremities, and rapidly spreads over nearly the whole surface of the body. The scales are quickly produced and thrown off, and the skin is red, deeply furrowed, thickened, and rigid, so that motion is often painful and difficult.

Another specimen of the same species, in which the scales are more minute, and more readily exfoliate. Fig. 2.-PSORIASIS diffusa ; a variety of the same species, which occurs chiefly about the hands and arms of washerwomen, in consequence of the irritation of soap, and which is generally more highly inflamed, chopped, and tender, than any other variety of the disease.

Delineations of Cutaneous Diseases, 11. - London, Henry G. Bohn, 1815 (1849), 1 hand colored engraved plate, 246 x 242 mm, added a descriptive text leaf. PSORIASIS diffusa ; a variety of the disease which often affects the back of the hand of bakers, and has been thence called the Baker s itch. It is accompanied with numerous chops and fissures about the knuckles, and the surface is a little tumefied, and the scaliness slight. In his second edition of this plate, Dr. Willan had introduced a figure of the PSORIASIS inveterata; but the representation was so totally- inadequate to convey any idea of the disease, that it has been deemed necessary to expunge it, and to restore the engraving to its original state. A new representation of this form of Psoriasis will be given in the next Fasciculus, Plate XIII. "In 1814 Bateman acquired the copyright to the engravings in the Willan treatise.
