| On Geometrical Ratios existing between’ Equivalent Numbers. 
Tue First Part of this paper was devoted to the examination 
of yelations between the equivalent numbers of certain element- 
_ ay bodies depending upon the number 44-45, and it was 
attempted to show :— 
Ist. That such relations extend to nearly all the elements :— 
_, 2d. That the particular groups collected together by this rela- 
_ tion consist of bodies whose properties are analogous, and that 
the classification is in harmony with the distinguishing charac-

3 familiar arithmetical relations which have been heretofore exclu- 
Sively studied by chemists. 
m 
t renders this the more remarkable is, that all three of these 
lst sy Nees are striking exceptions to Prou ’s law that the 
“qivalents of the elements are exact multiples of that of hy dro- 
3 they all have decimals, zirconium 22-4, potassium 39-2,
