Most sponge-holders are made much too long in the cylinder, the proper dimensions for general use being about x 1J inches, and the sponge should he large enough to fit the cylinder tightly, or it will be apt to slip out, and when not in use it should be taken out of the holder and kept in water until required again. Conductors with fixed sponges, although convenient, soon become fouled, and interrupt the current unless the sponges are frequently renewed. The disk rheophore covered with wash-leather is very generally useful, and by using the edge it may be made to answer in the majority of cases for a pointed conductor. It has also an advantage over the sponge of allowing firm pressure to be made without the inconvenience of water being squeezed out.* The conductors I have just described and a wire brush, comprise those supplied with my instruments.
