  • (v.) To subject, as an ore, alloy, or other metallic compound, to chemical or metallurgical examination, in order to determine the amount of a particular metal contained in it, or to ascertain its composition.
  • (v. i.) To attempt, try, or endeavor.

Qualitative


Definition:

  • (a.) Relating to quality; having the character of quality.
