ANALYSIS, in Rhetoric, is that which examines the connexions, tropes, figures, and the like, inquiring into the proposition, division, passions, arguments, and other apparatus of rhetoric. Several authors, as Freigius and others, have given analyses of Cicero's Orations, wherein they reduce them to their grammatical and logical principles; strip them of all the ornaments and additions of rhetoric which otherwise disguise their true form, and conceal the connexion between one part and another. The design of these authors is to have those admired harangues just such as the judgment disposed them, without the help of imagination: so that here we may coolly view the force of each proof, and admire the use Cicero made of rhetorical figures to conceal the weak part of a cause. A collection has been made of the analyses formed by the most celebrated authors of the 16th century, in 3 vols. folio. ANALYSIS is also used, in Chemistry, for the decomposition of a mixed body, or the separation of the principles and constituent parts of a compounded substance. To analyze bodies, or resolve them into their component parts, is indeed the chief object of the art of chemistry. Chemistry furnishes several means for the decomposition of bodies, which are founded on the difference of the properties belonging to the different principles of which the body to be analyzed is composed. If, for example, a body be composed of several principles, some of which have a great and others a moderate degree of volatility, and, lastly, others are fixed, its most volatile parts may be first separated by a gradual heat in distilling vessels; and then the parts which are next in volatility will pass over in distillation; and, lastly, those parts which are fixed, and capable of resisting the action of fire, will remain at the bottom of the vessel. ANALYSIS is also used for a kind of syllabus, or table of the principal heads or articles of a continued discourse, disposed in their natural order and dependency. Analyses are more scientific than alphabetical indexes; but they are less used, as being more intricate. ANALYSIS is likewise used for a brief, but methodical, illustration of the principles of a science; in which sense Analytic sense it is nearly synonymous with what we otherwise call a synopsis.
