![IM'KCDI CTION. to facilitate to convey information in . which is no! always in relation with their out- artificial method of arriving the knowledge of species, without which, ml no conclusions can be held I that Plenck had no intention of giving the skin according to their nature; i; is therefore unfair to reproach him with the diversity of the elements which i I nt imperfections which particularly from his not having always stuck with sufficient cl what were in fact the most striking external tea which he has arranged together in each of his nt groups. Willan,1 i tern of classification, starts essentially from the ' nek; but instead of attaching himself, like the Ger- man author, to the most striking feature of the diseases of the skin, period in their progress, he assumes the character their highest pitch of development—at their //it, and before they have undergone any consecutive alte- ment of his distribution. In the majority of cases, es of the skin are much more strikingly characterized at this lither before or afterwards, by the appearances which or follow them, and which are frequently common to 1 affections. Willan has, in conformity with this view, sup- es of ulcers, crusts, &.c. His groups are better ordered than those of Plenck. He never mingles, as the latter does constantly, symptoms with diseases ; and a much more accurate knowledge of the eruptions themselves than Plenck possessed, enabled Willan to judge more precisely of their proper places in his different groups. Several even extremely natural, such as the papulce, the squama, and even fjie exanthemata, if purpura be struck out of it; ii the other hand, the ti&ercula includes diseases of the most dissimi- lar descriptions. The great characteristics of Willan's writin ipress they bear of the scientific spirit that guided him in his at precision, and the purity of his descriptions; irticular pains he takes to select well, and to use judiciously, his technical expressions; lastly, the taste and the sound judgment he lys in his interpretation of the ancients. If there be aught with which he is chargeable in the way of omission, it is with having paid too little attention to the relations of the diseases of the skin to the f the constitution, to anterior diseases, and to those affections which are attributed to their repercussion. His therapeia is in gene- : his practice, his writings, and the works which have issued from I , contributed powerfully to extend the free use of pur- mal employment of a variety of powerful medi- cines, such as the tincture of cantharides, the mineral acids, and the preparations both of antimony and arsenic in the treatment of cutaneous ions. man, by completing the works of Willan, and reproducing them in an ! nt form,2 contributed greatly to extend a knowledge of the diseases of the skin. Bateman also in his edition of the atlas, commenced by Willan, gave figures of a considerable number of diseases of the skin.3 works of these celebrated pathologists were recast by Gomez,4 and published in the shape of a synoptical table of the diseases of the skin; bv Em, Szalay5 in his inaugural dissertation, in the form of a I; and by Bertrand6 and Ab.

Darstellung der Hautkrankheiten nach Willan's System bearbeitet The little work entific chw it is simply a . and of • M'lv ''' i;,; having for the most part a practical end. It includes ins cheloid tumour, oi strumous tetter, of eruptions about tfa organs of men and women, and a variety of observations on the con- stitution, and on the physical and moral character of individ habitually subject to herpetic affections. The author speaks ol influence which diseases of the skin of the lace exert on the ts and habits of females of a certain age; he mentions the relation the diseases of the skin to gout and the affections of the uril is; he dwells on the difficulties almost always connected \ the treatment of cutaneous diseases, and the frequency of relaj among individuals who will not consent to follow the course pre- scribed, whether it be medicinal or dietetic, in every the most minute particular. At a time when almost all the chronic diseases of the skin of face, trunk and extremities, were designated in France under the name of dartres, which corresponds to the English word tetter, was interpreted by the Latin term herpes, the college of medicine Lyons proposed as the subject of a prize: To determine the vafi species of tetter, their causes, their symptoms, and the diseases I depend on them. The prize was awarded to the dissertation of H. J. A. de Roussel.9 Sauvages10 had admitted nine species of /.< (independently of psydracia, hydrcea, epinyctis, rosacea, ephelis and vitiligo); comprising, 1st, furfuraceous tetter; 2d, crusted tetter; 3d, miliary tetter; 4th, eating letter; 5th, syphilitic tetter; 6th, garter-like tetter; 7th, collar-like tetter; 8th, pustular tetter (Da boutonnee); and 9th, zona. The species admitted by Roussel are in general better characterized, and bear greater affinity to those which are still described at the present day under other names. Under the head of herpes furfuraceous, he evidently includes the papular and squamous affections ; in his squamous running tetter or dartre vive, we recognize the characters of excoriated eczema, and his crusted tetter corresponding to our impetigo. Roussel endeavoured to discover and to point out the signs by means of which we may ascertain whether a cutaneous eruption is the depositary, as it were, the crisis or the solution of an internal disease, or exists per se; and this foi one of the striking characteristics of his work, which is further remark- able for the efforts the author makes to approximate and bring into harmony the imperfect descriptions of his predecessors, rendered - more obscure by the diversity of nomenclature universally employed. The small treatise of Poupart11 has no interest otherwise than as it contains several observations on the repercussion and on the metas- s of chronic diseases of the skin, and even the greater numbei his facts are derived from the writings of Ballonius, Mead, Sauvages, Raymond, Tissot, &c. The instances he gives are dysurise, leuct - rhceas and affections of the brain and lungs, supervening on the c of cutaneous eruptions. Poupart also studied the action of the ane- mone pulsatilis in cases of tettery eruption, and quotes several in- stances of its efficacy in their cure. Jackson12 has treated at: great length of the causes and of the natun the diseases of the skin ; which he nevertheless only considers in a \ vague and general manner. He divides them into three groups; 1st. Morbid secretions of the subaceous glands; 2d. Morbid states of bulbs of the hair; 3d. Morbid conditions of the cutaneous vessels. Chiarugi13 limits his researches to the chronic and crusted (sor» diseases of the skin. He divides them into three orders: 1st crus papular diseases (impetigo, herpes); 2d, crusted phlycten'oid d - eases(achor, rogna); 3d, crusted pustular diseases (gotta rosea, lep tinea). Under the name of Impetigo, in the first group, he descril lichen pretty accurately, and gives a good definition of the disease • and, under the name of herpes, he includes the same diseases as von Th.
