    N° 3242 A.D. 1895 Date of Application, 14th Feb., 1895 Complete Specification Left, 20th June, 1895—Accepted, 3rd Aug., 1895 PROVISIONAL SPECIFICATION. Improvements relating* to Dressings for Wounds. I, Alfred Thamm, Doctor of* Medicine, of Duisburgerstrasse 62, Diisseldorf, in the German Empire, do hereby declare the nature of this invention to be as follows :— This invention has for its object, to produce a surgical dressing, which in most 5 cases renders bandages unnecessary, so that the free movements of the limbs will not be hindered by the same. FoJ|Jthis purpose I proceed as follows ; The wound is first covered with guttapercha, gauze, powder, ointment or other suitable material, if such covering is at all considered necessary or desirable, after wiiich a suitably shaped pad or lump of carbolized wadding or cotton-wool is spread 10 over the same, and well impregnated with collodion or photoxylene. The carbolic solution contained in the wadding has the property of sucking up liquids, in consequence of which the impregnation of the wadding proceeds rapidly through the whole piece, and causes the latter to harden quickly. The mass becomes almost as hard as plaster of Paris, but without producing a burning sensation, as is 15 the case in merely applying collodion with a brush. If plain Tvadding were used, instead of carbolized wadding, it would not suck up the collodion ; only the outer layers would take up collodion and become hard, and the dressing 'would not adhere or keep in place as firmly as is required.

I, Alfred Thamm, Doctor of Medicine, of Duisburgerstrasse, 62, Diisseldorf, 25 in the German Empire, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement:— This invention has for its object, to produce a surgical dressing, which in most cases renders bandages unnecessary, so that the free movements of the limbs will 30 not be hindered by the same. For this purpose I proceed as follows ;—• The wound is first covered with guttapercha, gauze, powder, ointment, or other suitable material, if such covering is at all considered necessary or desirable, after which a suitably shaped pad of wadding or cotton wool is spread over the same, and well impregnated with collodion or photoxylene. The wadding absorbs the liquid 35 and hardens rapidly. The mass becomes almost as hard as plaster of Paris, but without producing a burning sensation, as is the case in merely applying collodion with a brush. I prefer to use carbolized or similarly impregnated wadding, in order that the absorption of the collodion may be more rapid and uniform, than in the case o 40 ordinary wadding. Carbolized wadding suitable for this purpose may be prepared [Price 8<A]
