VI. Our Graphics. 



The values of all departures given in Table V. are represented to 

 the eye in our two graphics. 



Fig. I gives all the larger departures and as many of the smaller 

 ones as space would permit. The scale used is 200 thousandths of 

 the unit of atomic weights to the inch ; or, what amounts to the same, 

 the unit of the atomic weights is represented by five inches in length. 



Fig. 2 gives all the departures of the central region on a scale 

 which is five times the one used in the construction of the first figure. 

 Hence in Fig. 2 the unit is represented by a line of twenty-five inches ; 

 or, in other words, it shows forty thousandths to the inch. 



The vertical of the ordinate represents the departures of vana- 

 dium, while the departures of the elements combined with vanadium 

 are set off on the horizontal as abscissse. 



The results for a complete analysis of any given compound are 

 therefore set off on the horizontal line drawn through the point on 

 the vertical determined by the departure for vanadium.
