Abstract
IN my former communications to NATURE it has, I believe, appeared (1) that the induction currents used by Du Bois-Reymond, Duchênne, and other observers for physiological and therapeutical purposes were only arbitrarily and very insufficiently measured; (2) that the simplest and most practical instrument for their measurement is a delicate electro-dynamometer; (3) that in consequence of their extreme smallness, every available method must be employed to reduce the sluggishness of such an instrument without impairing its accuracy; (4) that an instrument of this character, shown by me before the Physical Society at Oxford in June 1882, had answered very well, indeed better than a more expensive apparatus designed by Prof. Kohlrausch for larger currents.
