To this purpose we note (fig. 2) the lime in minutes on the abscis, 

 the muscle-power in myodioptries on the ordinate.

Supposing the power, at the beginning of tlie examination, to be 

 '24 myodioptries, when after 5 minutes tliere is no sign of paralysis, 

 then one notes point B on the abscis of 24 and the ordinate of 5; 

 if, after 10 minutes, the muscle is paralysed for '/a'^ P*ii''. '''e" 

 the power is still 21 myodioptries, and one has found a point R 

 on the abscis of 21 and the ordinate of 10. Continuing in this 

 manner, and continually determining Ihe degree of paralysis of the 

 muscle, one can find Jlnd plot out the entire paralysis-curve A. B. 

 C. D. E. This examination gives an excellent control of the correctness 

 of the method; for as soon as the curve surpa.sses Ihe abscis of the 

 physical near point, we can also directly find the degree of paralyses 

 by determining the absolute near point. The part CD. of the curve 

 can therefore be ascertained in two entirely different ways. 



If these two give entirely Ihe .same result, or if they agree
