Transcriber's notes:

(1) Numbers following letters (without space) like C2 were originally
      printed in subscript. Letter subscripts are preceded by an
      underscore, like C_n.

(2) Characters following a carat (^) were printed in superscript.

(3) Side-notes were relocated to function as titles of their respective
      paragraphs.

(4) Macrons and breves above letters and dots below letters were not
      inserted.

(5) [root] stands for the root symbol, [oo] for infinity, and [alpha],
      [beta], etc. for greek letters.

(6) The following typographical errors have been corrected:

    ARTICLE GYROSCOPE AND GYROSTAT: "... in such a manner that a point
      on the pendulum at a distance..." ''pendulum'' amended from
      ''pedulum''.

    ARTICLE GYROSCOPE AND GYROSTAT: "Interpreted geometrically on the
      deformable hyperboloid, flattened in the plane of the focal ellipse
     ..." ''hyperboloid'' amended from ''hyperboloia''.

    ARTICLE HAEMOSPORIDIA: "... this does not represent reserve
      material, but is an excreted by-product derived from the
      haemoglobin." ''by-product'' amended from ''bye-product''.

    ARTICLE HALIFAX, GEORGE MONTAGU DUNK: "About this time he sought to
      become a secretary of state, but in vain, although he was allowed
      to enter the cabinet in 1757." ''become'' amended from ''became''.

    ARTICLE HALLEFLINTA: "Rocks very similar to the typical Swedish
      halleflintas occur in Tirol, in Galicia and eastern Bohemia."
      ''similar'' amended from ''similiar?''.
