for thirty-six pairs, represented in fig. 18, is 20 centimetres high, 

 20 long, and 18 wide. 



" A double top C D E F, which forms the upjjer part of the 

 box and covers the battery, serves to support the various ap- 

 pendages necessary for the use of the instrument. These are, 

 A, A', electrodes which deliver the current, and fiom which the con- 

 ducting wires proceed ; M, j\I', handles by v^hich to combine, in 

 greater or less number, the elements of the battery, and to direct 

 the current in the course desired ; G, a galvanoscope, serving to 

 show the passage of the current. 



"All the pairs, being identical in size and arrangement, can be 

 placed in the box one for another ; and they are so constructed 

 that they can only be placed in a position proper for their being 

 combined. The various contacts are made automatically by 

 putting the elements in place.
