to measurements, not hitherto published, by Gmkun. In reducing 

 my observations I have therefore taken 22765 as die value of the 

 magnetic force belonging to (lie mean of the two numbers mentioned 

 for the separation. 



7. The results are graphically represented in the following dia- 

 gram. The abscissae are the separations of line 5770 in A.U., and 

 the corresponding tield intensities in Gauss, the ordinates the corre- 

 sponding separations of 5791. The small crosses represent the obser- 

 vations of the table in § 5. 



The full freehand lines give the best mean result of the observa- 

 tions. (See § 9). 



The signification of the upper dotted straight line is the following. 



The mean of the 34 single values of the asymmetry is 0. 036 A. U. 

 The straight dotted line has been traced parallel to the lower line 

 at a distance of 36 thousandths of an Angstrom unit, measured 

 along the ordinate. 



8. We may infer from our observations that with the fields used, 

 from 15000 to 30000 Gauss, an asymmetry undoubtedly exists which
