† a. In 17th and 18th c.: = MICROSCOPE (obs.). b. Subsequently variously employed in narrower sense. Goring (1830) applied it to denote a compound microscope of any kind; but as the term was most frequently used by him in his description of the Amician and similar reflecting microscopes, it is now commonly understood as a distinctive name of that class of instruments.
