    *— Darlow Seymour's New Magnetic Compound. adhesive substance, but we do not confine ourselves to these exact proportions, as they will depend upon the quality or kind of gums used. The gums, india-rubber, or gutta percha are reduced to a pasty or fluid consistency by any of the well-known methods used for that purpose, when the steel filings 5 or other magnetic element of the compound is introduced and well in¬ corporated therewith ; then after such incorporation of the two elements of the compound it is either rolled into sheets or moulded into any required shape, and, if required, then vulcanized. If rolled into sheets these sheets are cut into the required shape, and then magnetised, either by bringing the 10 compound in contact with an excited electro-magnet or by any other suitable method of inducing a magnetic condition of the magnetisable particles con¬ tained in the compound. And when our Invention is applied to the manufacture of magnetic chest protectors, belts, bandages, and similar uses, we prefer to apply the com- 15 pound in the shape of bar magnets ; for these purposes the sheet is cut into strips or bars, and applied to any suitable fabric. When it is required to produce a magnetic compound without elasticity and flexibility, pitch, asphalte, or other bituminous substance may be used as the vehicle for holding the magnetic element, and an increased proportion of the latter may be used. 20 This magnetic compound is applicable to horticultural and agricultural purposes, and when intended to be so applied it is or may be manufactured in small pieces or globules. The magnetic compound, whether more or less elastic and flexible, manufactured as above stated being capable of retaining and imparting its magnetic influence may be applied to various curative 25 purposes and other uses, and may be employed in the manner above stated in magnetic belts, bandages, or similar articles, and in all cases in which magnetic influence is required to be locally applied, either to human beings, animals, or vegetables. Having thus described the nature of the said Invention, and in what so manner the same is to be performed, we would remark that we do not claim the application of our Invention to magnetic plasters for the human body composed of resinous or bituminous substances or compounds and steel filings, as such plasters have been used ; but what we do claim as of our Invention is, the production of a magnetic compound or substance composed of a 35 gummy, resinous, bituminous, or other suitable adhesive substance, with magnetic or magnetisable particles incorporated therewith in such a manner as to adapt it for appbcation to various useful purposes herein-before referred
