These results show a small, but very clearly marked 

 systematic variation of the analytical ratio ^ dependent upon 

 the amount of substance used. 



Indeed, Crookes has the same failing which we showed 

 Stas to have been afflicted with in his analytical operations ; 

 namely, his results vary with the amount operated upon. 

 True Atomic Weights, 1894, pp. 80-85. 



We are, indeed, very sorry to detect the symptoms and 

 signs of this Morbus Stasii in the record of Mr. William 

 Crookes; but the readers now see it is actually there, as a 

 fact; and I guess even Sir William Crookes will admit that 

 we have diagnosed this case correctly. 



To allow for the slight variations to which even Crookes 

 is entitled, we shall group these results according to the 

 mean weight plainly marked in the individual amounts; 

 operated upon. We find the following results:
