The direction of the transverse effect in a conductor cannot be given by a knowledge of the magnetic properties of a body, for we find, if we assume the direction to be positive in magnetic bodies, negative in diamagnetic, that nickel, palladium, platinum, manganese, zinc, cadmium, antimony are exceptions. Again, if we look for a relation between the direction of the Thomson effect and that of the transverse effect, we have another long list of exceptions, including antimony, cadmium, zinc, platinum, bismuth. On the other hand, if we arrange the metals in a thermoelectric series, we find that, with the one exception of cobalt, the metals from bismuth to silver have a negative transverse effect; those from zinc to tellurium a positive; and the agreement goes further, for bismuth, which is at one end of the series, has a large transverse negative effect; and as we go up the series, the effect decreases in numerical value; while tellurium, which is at the other end, has a large positive effect, and as we come down the effect again decreases.
