Underlying the thinking of Dumas and others was the belief that elements were stable compounds of simpler substances. Dumas suggested that transmutation might be possible after all, and the reason for the failure of the alchemists to produce gold was that they had started with unrelated elements. Faraday also doubted the status accorded to elements. It was the discovery of thallium by Crookes in 1861 that prompted Faraday to remark that a discovery really worth making would be the decomposition of an element (Chapter 7).

Salt was first electrochemicaHy decomposed by Cmickshank ia 1800, and ia 1808 Davy confirmed chlorine to be an element. In the 1830s Michael Faraday, Davy s laboratory assistant, produced definitive work on both the electrolytic generation of chlorine and its ease of Hquefaction. And ia 1851 Watt obtained the first Fnglish patent for an electrolytic chlorine production cell (11). 

The second of Faraday s observations was that the weights of different elements that were deposited by the same amount of electricity formed simple whole-number ratios when divided by the atomic weights of these elements. For example,... 

The height of a given X-ray peak is a measure of the amount of the corresponding element in the sample. The X-ray production cross-sections are known with good accuracy, the beam current can be measured by, for example, a Faraday cup (Figure 4.1) and the parameters of the experimental set-up are easily determined so that the sample composition can be determined in absolute terms. 

In Ostwald s Faraday Lecture of 1904, he demonstrated that these early-nineteenth-century laws could be deduced from the definition that "a substance or a chemical individual is a body which can form hylotropic phases within a finite range of temperature and pressure." In "Elements and Compounds," 185201, in C. S.
