174 STASIAN FOLLY AND FRAUD. 



from the other curves relating to other work of Stas also 

 drawn on a smaller scale for the silver used. See Plate II. 



We shall, once more, give all the essential data, exactly 

 as given by Stas; gross actual errors of Stas we shall point 

 out, as we did in our True Atomic Weights of 1894. But 

 we shall be as brief as possible referring for additional 

 details to the above work of ours, published in 1894. 



Syntheses of Silver Nitrate by Stas. 



Stas made ten syntheses of silver nitrate from pure silver; 

 we designate them Nos. i to 10, in the order in which Stas 

 actually made them. The results were published by him in 

 his Recherches of 1860 (Nos. i to 8), and in his Nouvelles 

 Recherches of 1865 (our Nos. 9 and 10). 



The full and complete record is reprinted in his Oeuvres, 

 T. I., 1894; for the first series, Nos. i to 8, on pages 342 to 

 346; for his second series, Nos. 9, 10, on pages 717 to 725. 



See also my True Atomic Weights, pp. 75 to 88; 1894; 

 also Clarke, Constants, 1897, p. 63. 



Our re-calculation of the analytical ratios gives essenti- 

 ally the same results as all others have found, and as given 

 by Stas himself; the analytical ratio is the weight of the 

 nitrate divided by that of the metal. 



In other words, the analytical ratio expresses the amount 

 of silver nitrate per unit of "weight of silver used. 



It cannot be expected that we should again reprint these 

 ratios here ; they have been printed often enough, even by 

 ourselves (True Atomic Weights, p. 77, p. 81) and repre- 

 sented graphically on plate I facing this last page just 

 referred to. 



As to these data, we must make the following brief 

 annotations: 



No. 7 is excluded by Stas himself; hence we cannot make 

 use of it here. He claims to have lost some material. We 

 cannot go back of his statement of fact. We accept it as a 

 matter of course. 



From all determinations, Nos. i to 5 and 7, we have found 

 that the reduction to vacuum amounted to 21 milligrammes
