Two sets of experiments in the reverse order were taken to 
eliminate any change that might take place in the deflection 
from weakening of the battery, or from polarization of the 
plates, or from set of the galvanometer-fibre. The constant 
distance between the centres of the plates was now diminished 
to 20 centimetres, when the following results were obtained, 
the ^^ shunt being employed.

Both therefore at the greater and at the less distance the - 
resistance is least when the platinum plates are edge on ; a 
result that could hardly have been expected for the longer 
distance, considering that the width of each plate Was only 
about 6 centimetres. 
March 1, 1878. 
In the following experiments one plate only was turned. 
The galvanometer had about the same sensibility as before. 
The j^y shunt was used when the distance between the 
centre of the plates was 90 centimetres, and the ^^ shunt 
when it was 20 centimetres. An electromotive force of 3*8 
volts was employed in each test.
