CARBON. DUMAS. 



zero; for the other two it operates in opposite directions, 

 balancing in amount. 



The case of Hardin shows exactly how demoralizing the 

 influence of the Chief Chemist Clarke has been. Concord- 

 ance, minute " probable errors " are insisted upon by this 

 High Muckamuck of the National Government. 



Hence the supply follows the demand; and with it, 

 truth and science are defaced, and a probably excellent 

 young worker wrecked. 



How long is this nation going to allow our official Olla 

 Podrida Cook to terrorize American students of Science and 

 to disgrace American chemistry? 



VII. THE ATOMIC WEIGHT OF CARBON. DUMAS. 



The great work done by Dumas in perfecting the process 

 of the quantitatively accurate combustion of the diamond 

 was strictly in line of the school of Berzelius, though 

 published as an attack on the Swedish chemist. 



It was soon followed by the perfection of the process 

 devised by Berzelius for the determination of the atomic 

 weight of hydrogen. In his later years, Dumas unfortu- 

 nately made use of the method of Pelouze and furnished 

 inaccurate data in great number. 



Having given (p. 39) all the experimental data of the five 

 combustions of Diamond, by Dumas, we need here only 

 present a summary of the results of all such combustions 

 published up to the present date. 



This reaction is atomically one of the most sensitive in 

 chemistry, so that four decimals here will give a much higher 

 degree of precision than five commonly used. 



C O2 : C = 44 : 12 = 3.66 667. Change 2204 low. 

 To 4. decimals : 3.66 67. Change 220 low. 



Accordingly, we shall state all results to four decimals 

 only, for carbon. The ratio is exactly n to 3. 



We shall also add the total weight in grammes, of diamond 

 burnt by each analyst.
