a galvanic current in the same direction. Distance of coil 10 centims. 
Galvanic current of 12 cells. 
9. Break induction anodic contractions before, during, and after passage of a 
galvanic current in the same direction. Distance of coil 9 centims. Galvanic 
current of 12 cells. 
10. Break induction kathodic contractions before, during, and after passage of 
a galvanic current in the opposite direction. Distance of coil 9’5 centims. 
Galvanic current of 4 cells. 
11. Break induction anodic contractions before, during, and after the passage 
of a galvanic current in the opposite direction. Distance of coil 7 centims. 
Galvanic current of 12 cells. 
12. Series of contractions by the break induction kathode, with increasing 
strengths of current. The figures accompanying each group of contractions 
denote the distance in centims. of secondary from primary coil. 
13. Effect of break induction anode with increasing strength of an opposed 
galvanic current. The first group of five contractions is taken in the absence 
of any galvanic current, the 2nd group with a galvanic current of 2 cells, 
the 3rd with 4 cells . . . , the 21st with 40 cells (19 milliwebers). Distance 
of coil 6 centims. 1000 ohms additional resistance in circuit. 
136. Effect of break induction kathode with increasing strength of an opposed, 
galvanic current. The first group of three contractions is taken in the 
absence of galvanic current, the 2nd group with 2 cells, the third with 
4 cells . . . , the 15th with 28 cells. Distance of coil 8 centims. No 
additional resistance in circuit. 
14. Series of make and break induction contractions, with and without galvanic 
current in circuit. Henry’s modification (E. M. F. of 30 volts; 100 ohms 
in primary circuit). Reading from right to left the first of each pair of 
contractions is by the make, the second by the break current. 1000 ohms 
added in circuit.
