But the belief died hard; the synthesis of urea remained isolated for many years; and many explanations were attempted by the vitalists (as, for instance, that urea was halfway between the inorganic and organic kingdoms, or that the carbon, from which it was obtained, retained the essentials of this hypothetical vital force), but only to succumb at a later date to the indubitable fact that the same laws of chemical combination prevail in both the animate and inanimate kingdoms, and that the artificial or laboratory synthesis of any substance, either inorganic or organic, is but a question of time, once its constitution is determined.'.

Martinengo Cesarescos Liberation of Italy (London, 1895) is to be strongly recommended, and is indeed, for accuracy, fairness and synthesis, as well as for charm of style, one of the very best books on the subject in any language; Bolton Kings History of Italian Unity (2 vols., London, 1899) is bulkier and less satisfactory, but contains a useful bibliography.
His power lies chiefly in the clear grasp of fact, in selection and synthesis, in the vivid narration of incident.
The fundamental chemical classification of matter, on the other hand, recognizes two groups of substances, namely, elements, which are substances not admitting of analysis into other substances, and compounds, which do admit of analysis into simpler substances and also of synthesis from simpler substances.
The above formula for piperic acid was confirmed by its synthesis by A.

Before proceeding to the actual synthesis of the sugars, it is advisable to discuss their decompositions and transformations.
The general principles of stereochemistry being discussed in Stereoisomerism (q.v.), we proceed to the synthesis of glucose and fructose and then to the derivation of their configurations.
The main principles of the Comtian system are derived from the Positive Polity and from two other works, - the Positivist Catechism: a Summary Exposition of the Universal Religion in Twelve Dialo ues between a Woman and a The g, g Elvis f Priest of Humanity; and, second, The Subjective Synthesis (1856), which is the first and only volume of a work upon mathematics announced at the end of the Positive Philosophy.

We progress by making explicit the oppositions contained in the fundamental synthesis, by uniting these opposites, analysing the new synthesis, and so on, until we reach an ultimate pair.
