A SUMMARY OF PROCEDURE 
FIG. 7. Arrangement of apparatus for calibrating the inducto- 
rium. A, ammeter; B, battery; C, standard coil; G, galvanometer; 
7, inductorium to be calibrated; K, make and break key; P, apparatus 
for physiological calibration;. R, resistance box; 5 and Si, switches. 
3. Determination of the inductance of the secondary 
coil (p. 50). 
4. Determination of for the secondary positions 
jL 
whose mutual inductions have been established (p. 53). 
5. Physiological corroboration of this calibration by 
the v. Fleischl method (p. 56), accompanied by physi- 
ological determination of the " calibration numbers " for 
the inner secondary positions (p. 58). 
6. Construction of a curve to establish calibration 
numbers for intermediate secondary positions (p. 56). 
7. Determination of the constant C in the formula for 
make shocks (pp. 94 and 104).
