Original Summary:
"Demonstrates proof of Dalton's convictions that matter comes in discrete units and that experimental proof of this characteristic, in addition to other evidence, gives a foundation for scientific laws and the periodic table. Experiments by Robert St. George are interpreted by Jerold R. Zacharias, MIT. Laws of definite proportions are illustrated by the oxides of nitrogen (N2O, NO and NO2) as exhibited by color, ability to support combustion, and melting and boiling points. A reaction of each of these gases with a known weight of copper to produce copper oxide and nitrogen shows evidence that the proportions of nitrogen and oxygen varies in small, whole-number relationships, but that more experimental data is required to determine the chemical formula for these nitrogen oxides." - Summary from Worldcat.
