JUDECRECHOQJ0LCJJJLJCI together. I have discovered that when so wound the effect of the small curvature of the wire itself is overcome and the co11k behaves as a conductor of a large radius of curvature, corresponding to that of the drum. This feature is of considerable practical importance. The lower end coil B should be somewhat below the uppermost turn of coil A. This, I find, lessens the tendency of the current to pass along the support F¹. When it is desirable for some reason or other to place the turns of the coll leading up to the terminal far apart, a conductor presenting everywhere, outwardly, a surface of a large radius of curvature, should be employed. 31 -73718 the 733
