    [mpts. in Electro-mcujvetic Coils fov Treating Live Animal and other Objects. this battery is connected by a flexible conductor C with the primary terminal Id of an induction coil E of any approved construction, and the othei piimai^y terminal G of the induction coil E is connected by a negative flexible conductor T with the negative pole II of the battery, thus completing the primary circuit. A flexible conductor I connects with secondary terminals J and K on the indue- 5 tion coil E, thus completing the secondary electric circuit. Each of the flexible conductors C, E and I is in the form of a cable (see Figure 5), the conductors C and F having portions formed into cable-coils L, M, N, 0 and P, and the conductor I having a portion formed into a cable coil Q. The term “cable-coil” denotes a plurality of insulated conductors, each forming ]() a strand of a cable which is laid into a desired number of convolutions to form each cable-coil capable of producing an effective field of magnetism whenever an electric current is sent through the flexible conductors F, C and I. Within the magnetic field of the cable-coils L, M, X, 0 and P or any of them may be placed an object or objects for receiving magnetism, and in a like manner 15 the cable coif Q may be arranged around a human being or around a bed of plants or other object, to bring the same within the magnetic field or sphere of magnetic influence of the cable-coil. The portions of the positive and negative conductors not required to apply magnetism should be as close to each other as the necessary insulation will allow 20 and the current flowing oppositely in each (the arrows indicate the direction of the current) ; this will, practically, prevent radiation of magnetism from that portion, and whenever it is desirable to coil a portion of the positive and negative conductors adjacent to each other in,the same circuit to get the best combined effect of the magnetism from said portion, they should each be coiled in the same 25 direction, and to get the best effect of the magnetism where only one coil is formed in either adjacent conductor in the circuit it should be coiled so that the current in the nearest portion of the other conductor shall flow in the same direction as the current in the latter conductor. Whenever the positive and negative conductors contact with each other when the current is flowing in 30 opposite directions in each (as shown by the arrows), the radiation of magnetism from both will be retarded or practically nil. The size of the plant bed or portion of soil or other object bathed with the magnetism, is regulated by the quantity and pressure of the current and the length and size of the conductor. When the ordinary alternating current of electric lamp circuits is employed 35 in my method there may be as a regulator of the current a lamp or lamps burnino- in the circuit and also a cut-off. And when the direct electric current of electric lamp currents, or the current from an electric battery is employed in mv method, it must be transformed into a frequency current by’a transformer on the circuit formed by the conductors and a cut-off, or poles, of the battery. There mav be, too, in addition to the transformer, a lamp or lamps burning in the circuit as a governor when using the ordinary direct electric lamp current, other well- known governors, such as a rheostat, might be used on the circuit instead of a lamp or lamps 40 The coils or forms described by the conductors are preferably coiled as com pactly info cable-form as the necessary length of conductor will allow and the conductor is insulated.
