    Gages Improved Chemical Compounds for Tissue, Bandages, Wafers, Qc. enrolled in Her Majesty’s High Court of Chancery within six calendar months next and immediately after the date of the said in part recited Letters Patent, as in and by the same, reference being thereunto had, will more fully and at large appear. NOW KNOW YE, that in compliance with the said proviso, I, the said 5 Jean Paul Gage, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are described and ascertained by the following statement thereof, that is to say:— My Invention consists in chemical compounds formed of vegetable and mineral substances, constituting kinds of vegeto-metallic tissues, serving va- 10 riously prepared to devellop with great facility the electric fluid, and which may be conveniently applied as bandages on the human body for the treatment of diseases and surgical purposes. The substances which I use for the com¬ position of these different vegeto-metallic tissues are,—First, rosins, resinous gums, such as india rubber, gutta percha, and other similar substances; 15 secondly, metals having the virtue of producing electricity. I employ pre¬ ferably copper and zinc, but without excluding other metals which have the same quality of generating electricity. I will now proceed to describe the mode of making these different vegeto- metallic tissues, which I will designate by the Numbers One, Two, Three. I 20 mix with the substances, or I apply on the substances above mentioned, first, metals reduced to a powder more or less fine; secondly, the same metals in lamellated particles; thirdly, the aforesaid metals in the shape of blades of variable length, breadth, and thickness. Tissue Number One, with metals in a powder.—To manufacture this tissue 25 I mix the copper and zinc reduced to a powder with the vegetable substances above designated, after having purified and liquified them by known processes. The metals in the state of powder enter in this composition in proportions which are varied according to the quantity of electricity which I wish to obtain. When the different substances are thoroughly mixed, I make of 30 them two kinds of preparations; the first consists in reducing in sheets more or less thin by means of a heated roller the said vegeto-metallic mixture, softened by heat and brought to a plastic consistency. The second consists in applying the said mixture on a tissue of silk, cotton, or flax, either by means of a laminating machine, or by any other means. The 35 first preparation is applicable to surgical medical bandages; the second I ' use to prepare the vegeto-metallic or electro-magnetic tissues Numbers Two and Three, which I will now proceed to describe. “Tissue Number Two, with metals in lamellated particles.”—When I have
