here, therefore I will only touch slightly on this matter now. 
I have given the name Pulsations to these wave motions in the 
curves, contrasting them thus with the Spasms, because of their 
resemblance to similar motions in the Seismograms, which were first 
detected by v. ResBeur-Pascnwitz and afterwards by MILNE and 
EuLert, and to which this name was given by von REBEUR. 
I have compiled statistics of the occurrance of these Pulsations in the 
years with narrow registering curves, which led to the following result:
