140 ABSOLUTE ATOMIC WEIGHT. 



scientific life and honor of chemists, like myself, who tried 

 to point out that poison and wished to remove the same. 



Taking Clarke's value, from the determinations of 

 Crookes, exclusively, (namely from ratio (4) on page 187, 

 edition of 1897), thallium is 202.595 in Clarke's supposed 

 Hydrogen unit; hence for O= 16 exactly: 

 Tl 1=204. 139. 



Ostwald (Physik. Chemie, I, p. 113; 1891) gives 



11=1204.146 

 " accurate to the second decimal," hence 204.15. 



Both these valuations of Clarke and of Ostwald, rest upon 

 the value of N of Stas; each one having " selected" his 

 own particular value, but it is essentially that of Stas, say 

 N = 14.04. 



The fraction 0.15 or 0.14 on T1:=:2O4, is taken to con- 

 demn the true values, that they do not agree -with our 

 standard values. 



Poisoned water does not agree with good health or even 

 with life; does that prove water a poison ? 



Those not hardened in the errors of Stas during a life 

 time, and who have not undermined their own scientific 

 standing with boisterous and continued declamations on the 

 excellency, perfection, absolute accuracy, mathematical 

 exactness of Stas' values and methods, will not understand 

 that we do not close our work " right here." They think we 

 have demonstrated our case completely. 



I do not think that my work is done here. It is true, 

 Moses himself thought it sufficient to keep his people forty 

 years in the wilderness, to get rid of those unfit to live in the 

 land of promise, and our Stasian Chemists have been in 

 such a wilderness for about that length of time; but by 

 means of the crooked scientific press, they control, in these 

 press-darkened times, it seems forty years has not been 

 enough. 



At any rate, tve shall not rest our case at this point, but 

 proceed to the consideration of the atomic weights of boron 

 and of nitrogen, which in a most remarkable manner con- 

 stitute true and most comprehensive test cases , each in its own 

 way, covering the entire question in all its essential rami- 

 fications.
