which represent the value of the coefficient A in two sets of experiments, 
where the cat had not recovered from the shock, it appears that in 
this case the coefficient A according to its value will join those cases 
where the coefficient B has the smallest value which can occur in con- 
nection with the accuracy of the method. The mutual differences 
of these coefficients A in the two tables are greater than was to 
be expected from the method, and the successive deviations are 
distributed over the series of experiments in such a way, that they 
can certainly not be brought under a simple rule. 
In connection with the discontinuous tonus-tracings I have already 
pointed out these irregularities which appear after the muscle-reflex 
are has been interrupted. 
The distention-curves obtained from cats with intact spinal cord 
and under very slight narcosis are quite different from those which 
occurred when the medulla was cut at a high level. Ether was 
used as narcotic. The shape of these curves is in appearance perfectly 
accordant with the curves obtained by Mosso and BENEDICENTI for 
men, with their myotonometer. In this case the measurements gave 
for most curves increasing tonicity-quotients with increment of 
charge, within the interval over which the experiment ranged. Under 
some circumstances these curves show a point of inflection. The
