Mr. M. M. rattison Muir on 



out the series of acids. Further, the differences between the 

 numbers found for any two acids are nearly constant for the three 

 bases. 



In Table X. the differences are those between the number 

 found for isobutyric acid (which had the smallest observed 

 value) and that for each of the other acids. 



In Table IX. the vertical columns represent the constant 

 differences, in Table X. the horizontal lines.
