Qualitative \Qual"i*ta*tive\, a. [Cf. LL. gualitativus, F.
   qualitatif.]
   Relating to quality; having the character of quality. --
   {Qual"i*ta*tive*ly}, adv.

   {Qualitative analysis} (Chem.), analysis which merely
      determines the constituents of a substance without any
      regard to the quantity of each ingredient; -- contrasted
      with quantitative analysis.

Analysis \A*nal"y*sis\, n.; pl. {Analyses}. [Gr. ?, fr. ? to
   unloose, to dissolve, to resolve into its elements; ? up + ?
   to loose. See {Loose}.]
   1. A resolution of anything, whether an object of the senses
      or of the intellect, into its constituent or original
      elements; an examination of the component parts of a
      subject, each separately, as the words which compose a
      sentence, the tones of a tune, or the simple propositions
      which enter into an argument. It is opposed to
      {synthesis}.

   2. (Chem.) The separation of a compound substance, by
      chemical processes, into its constituents, with a view to
      ascertain either (a) what elements it contains, or (b) how
      much of each element is present. The former is called
      {qualitative}, and the latter {quantitative analysis}.

   3. (Logic) The tracing of things to their source, and the
      resolving of knowledge into its original principles.

   4. (Math.) The resolving of problems by reducing the
      conditions that are in them to equations.

   5.
      (a) A syllabus, or table of the principal heads of a
          discourse, disposed in their natural order.
      (b) A brief, methodical illustration of the principles of
          a science. In this sense it is nearly synonymous with
          synopsis.

   6. (Nat. Hist.) The process of ascertaining the name of a
      species, or its place in a system of classification, by
      means of an analytical table or key.

   {Ultimate}, {Proximate}, {Qualitative}, {Quantitative}, and
   {Volumetric analysis}. (Chem.) See under {Ultimate},
      {Proximate}, {Qualitative}, etc.
