=No. 1.= A package of 25 steel sewing-needles. To be suitable for experiments in magnetism, these should be of good, hard steel, and not too thick. =No. 2.= A flat cork, about 1 in. in diameter and 3/8 in. thick. =No. 3.= A candle for annealing steel. =No. 4-15.= One dozen assorted annealed iron wires, from 1 in. to 6 in. in length. The iron should be very soft. =No. 16.= One English horseshoe magnet, 2-1/2 in. long, best quality. =No. 17.= A small box of iron filings from soft iron. =No. 18.= A compass (Fig. 5). The needle swings very freely; it is enclosed in a wooden pill box, the cover of which forms the support. =No. 19, 20.= Two soft steel wire nails, 2 in. long. =No. 21, 22.= Two pieces of spring steel, about 3 in. long and 3/8 in. wide, to be magnetized by the student and used as bar magnets. =No. 23.= An iron ring, or washer, about 7/8 in. in diameter. =No. 24.= A sifter for iron filings. This consists of a pasteboard pill box: Prick holes through the bottom with a pin. =No. 25.= A thin, flexible piece of spring steel, about 3 in. long and 1/8 in. wide. =No. 26, 27.= Two ebonite sheets (E S, Fig. 34), each 4 in. square. These are made with a special surface. They are very much better than the ordinary smooth ebonite. =No. 28.= One ebonite rod (E R, Fig. 34), 3-1/2 in. long, with special surface. =No. 29.= One ebonite rod, 1-3/4 in. long, with special surface, used to support the insulating table, No. 43 (I T, Fig. 32). =No. 30.= One piece of flannel cloth, 7 in. square. =No. 31.= Six sheets of tissue-paper, each 4 in. square. =No. 32.= A few feet of white cotton thread. =No. 33.= A few feet of black silk thread. =No. 34.= One support base (S B, Fig. 56). This is of thin wood, about 3-3/4 in. by 6-1/2 in., to one end of which is fastened a spool for holding the support rod (No. 35). =No. 35.= One support rod (S R, Fig. 56), 7 in. long and 5/16 in. in diameter. This rod has a hole in each end. The small hole is for holding the support wire (No. 36); the large hole is for the ebonite rod (No. 29). =No. 36.= One support wire (S W, Fig. 144). =No. 37.= One wire swing (W S, Fig. 29). =No. 38.= One sheet of glass, 4 in. square. =No. 39.= One bent hairpin (H P, Fig. 32). =No. 40.= Bottom of flat box (B F B, Fig. 32), 3-5/8 in. in diameter. =No. 41.= Top of flat box (T F B, Fig. 33). =No. 42.= One electrophorus cover (E C, Fig. 34), 3-5/8 in. in diameter. This has rounded edges, and a small tube is riveted into the top of it to hold the insulating handle, E R. =No. 43.= One insulating table (I T, Fig. 32). This is made the same as No. 42, and is supported by No. 29. =No. 44.= One insulated copper wire, 2-1/2 feet long. =No. 45.= One rubber band (R B, Fig. 33). =No. 46.= Six bent wire clamps (B C, Fig. 37). =No. 47.= One tin box conductor (T B, Fig. 42). This cylindrical conductor is about the size of an ordinary baking powder box. =No. 48.= One hairpin discharger for the condenser.
