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.'.

There are certain reactions, however, in which oxidation can be successfully applied to the synthesis of acids.
An important oxidation synthesis of aromatic acids is from hydrocarbons with aliphatic side chains; thus toluene, or methylbenzene, yields benzoic acid, the xylenes, or dimethyl-benzene, yield methyl-benzoic acids and phthalic acids.
The earlier papers deal chiefly with the properties and modes of synthesis of cloud chain hydrocarbons and their derivatives.
This work led naturally to the synthesis of many terpenes and members of the camphor group; also to the investigation of various alkaloids and natural colouring matters.
If we rest on the synthesis here described, the energy of the matter, even the thermal part, appears largely as potential energy of strain in the aether which interacts with the kinetic energy associated with disturbances involving finite velocity of matter.
The synthesis of citric acid was accomplished by L.
Kennett's Schweich Lecture (1909), The Composition of the Book of Isaiah in thelLight of Archaeology and History, an interesting attempt at a synthesis of results, is a brightly written b'ut scholarly sketch of the growth of the book of Isaiah, which went on till thegreat success of the Jews under Judas Maccabaeus.
" In this sense the doctrine of the Trinity was the synthesis, and summary, of all that was highest in the Hebrew and Hellenic conceptions of God, fused into union by the electric touch of the Incarnation."
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.
Discovered by Boyle in 1661, it was first carefully studied by Dumas and Peligot in 1831; its synthesis from its elements (through methane and methyl chloride) was effected by Berthelot in 1858.
The only possible synthesis is that of the Christianity common to all; as institutions, though they possess many features in common, their history is separate and must be separately dealt with.
In the language of a later period this principle may be expressed as the absolute synthesis of subject and object; no object exists apart from Mind.
But this synthesis is not brought forward prominently by Berkeley.
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.
