This again shows that zinc in this form is unfit for potential 
measurements. 
In the tables now following the E. M. F. of the amalgam cells 
with amalgams of higher concentration are indicated at 0°.5 in volts. 
The times are hours after the construction of the cells. The and 
— signs placed before the potential difference indicate that the least 
concentrated amalgam forms the positive, or the negative pole 
respectively of the cell investigated.
