These several results, the different sets being distinguished by plain 

 crosses or crosses with a dot, are laid down on the diagram, Fig. 1, to 

 which are also added other results already published from former 

 experiments ; these latter have a ring on one of the members of the 

 cross. The crosses for two disks, up to 11,000 inclusive, are taken 

 from the table in Part III of our researches,* those for the point and 

 disk from Table XI in Part I, p. 84, and the table in the same part, 

 p. 116 ; those for two points, from Table Xllla, Curve XVa, p. 86, 

 separate copy p. 32, and the table, p. 118, separate copy p. 64, of Part T 

 of our researches. f 



Through the absolute observations, curves were drawn as on the 

 diagram to represent the mean of the experiments in Tables I, II, 

 and III, represented on the diagram by plain crosses (without a ring). 

 Prom these curves were deduced the numbers given in Tables IV, V, 

 and VI, in C.Gr.S. units.
