Mr. A. K. Chapman on the 



Table gives the numbers, and fig. 2 is a plot of both for an 

 alloy containing 1 per cent, tin ; the numbers are all 

 referred to copper, which is taken as unity.

It is seen that both effects decrease rapidly with increasing 

 field, while the sign is that of the effect in bismuth. The 

 two curves are nearly parallel, the Corbino effect being the 

 smaller and falling to zero at 8910, where the Hall co- 

 efficient has a value of 1550 referred to copper. 



In the case of an alloy containing about 2 per cent, of 

 tin the conditions are somewhat different, as may be seen 

 from the Table and fig. 3.
