120 ABSOLUTE ATOMIC WEIGHT. 



XI. THE ATOMIC WEIGHT OF THALLIUM. CROOKES. 



Praemonitio: Mr. William Crookes, now Sir William 

 Crookes, as editor of the Chemical News, has, on two 

 occasions, about a quarter of a century apart, grossly 

 abused his position as editor against me, and by wilfully 

 misleading his subscribers, has defrauded them. 



About 1868 his "News" gave a review of my (i Pro- 

 gramme der Atom-Mechanik," of 1867, showing that the 

 writer of that pretended review had never read, probably 

 never seen, the book he abused. 



After the publication of my True Atomic Weights in 1894, 

 I sent to Mr. William Crookes, on September 4, 1895, a 

 complimentary copy with a letter, stating that the book was 

 sent to him personally (not as editor, not for revieiv) and 

 referring to the action above mentioned, supposing that 

 some of his writers had imposed upon him, it seeming 

 incredible to me that a man in his position could have 

 committed so low an act. 



That the low act was Mr. William Crookes' own, is fully 

 proved by the ranting and denunciatory review given by this 

 same pettifogging individual himself in his Chemical News, 

 vol. 72, pp. 231-232; 1896. This article had entirely escaped 

 my notice, until recently, when I looked up some experi- 

 mental results of Lord Rayleigh. 



This shows that Mr. William Crookes has a very crooked 

 character, that can hardly be excused on the ground of his 

 nauseous spiritualistic record. 



After stealing the personal copy for a u review " he 

 lacked, of course, the courtesy of sending me a copy of 

 his manufactured misrepresentations, made deliberately to 

 mislead his subscribers. Such is editor Crookes. 



Is he really too ignorant to comprehend ? 



It may, therefore, appear strange that I give a position of 

 great honor to this name Crookes, in line with the greatest 

 analytical chemists, from Berzelius to Seubert. 



I hereby specially give notice that I have exclusively 

 reference to the analytical chemist Crookes, and to his own
