Faraday Lecture

The theorem of Konowalow is the basis of the remarkably interesting Faraday Lecture to the London Chemical Society given by Ostwald in 1904. He points out that the considerations which have been summarised above in connection with Konowalow s curves lead to the general law that it is possible in every case to separate solutions into a finite number of hylotropic hoilies. A hylotropic body is characterised by the circumstance that it may be converted completely from one phase into another in a given process under fixed conditions (e.constant temperature or constant pressure) without variation of the properties of the residue and of the new phase. The apparent exceptions furnished by mixtures of maximum or... 

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 the preface of Ostwald (1907) he says "Three years ago, on the occasion of the Faraday lecture [Ostwald, 1904], I made an attempt to arouse the interest of chemists in these matters, but the result was not very encouraging. I know from personal experience that patient and continued labour can accomplish wonders even when the case seems hopeless. One must wait for the right time, and I am convinced that the time for this matter has arrived." But by the end of the book, when addressing metamerism, polymerism, and the role of valence in structure theory, he has to acknowledge that, when compared with "structure theory" his "purely empiri-...
