second series (made according to his second method) are 

 recorded, we find : Grammes. 



No. 17 0.089 86 9 



No. 18 0.090 144 



These two consecutive determinations, made when 

 Morley had gained experience in making 16 determinations 

 preceding in this series, and all 15 determinations of the first 

 series, differ by 



o.ooo 275 grammes. 



This is 2f5 millionths of a gramme, or 0.275 of a milli- 

 gramme; over a quarter of a milligramme! 



But when consecutive determinations differ by almost 

 three tenths of a milligramme what is the use of giving us 

 thousandths of the milligramme? 



This is either humbug or fraud, unless it be a contemptible 

 mixture of both ; tit's Stasian. 



We conclude that the weighings to the thousandths of 

 the milligramme are simply for show, and for fooling the 

 members of the American Association and of the American 

 Chemical Society. 



We shall have room for only a complete summary of his 

 five series, but shall express the results in milligrammes for 

 convenience. We shall not drop any of his fine work, for 

 the thousandth of a milligramme is just the same as the 

 millionth of the gramme.

The means are those actually given by Morley, in which 



a final little gnat of one thirty-thousandth was allowed 



for (see his p. 28), which amounts to 3 units in the last 



decimal here given, that is to 



one-third of a hundredth of a milligramme ! 



* The extremes of this series are put by Morley in brackets [ ] 

 commonly used to indicate their exclusion from consideration. 



Being rather greatly divergent, our friend of concordant results 

 naturally desires to suppress these results. But he fails to give any 

 reason for this exclusion. Hence we must keep them, as Morley's own 

 fine determinations.
