              The periodicaltimes of all the satellites. --Sir J.
                                                    Herschel.
        [1913 Webster]
  
     2. Performed in a period, or regular revolution; proceeding
        in a series of successive circuits; as, the periodical
        motion of the planets round the sun.
        [1913 Webster]
  
     3. Happening, by revolution, at a stated time; returning
        regularly, after a certain period of time; acting,
        happening, or appearing, at fixed intervals; recurring;
        as, periodical epidemics.
        [1913 Webster]
  
              The periodic return of a plant's flowering.
                                                    --Henslow.

     Periodic comet (Astron.), a comet that moves about the sun
        in an elliptic orbit; a comet that has been seen at two of
        its approaches to the sun.
  
     Periodic function (Math.), a function whose values recur at
        fixed intervals as the variable uniformly increases. The
        trigonomertic functions, as sin x, tan x, etc., are
        periodic functions. Exponential functions are also
        periodic, having an imaginary period, and the elliptic
        functions have not only a real but an imaginary period,
        and are hence called doubly periodic.
  
     Periodic law (Chem.), the generalization that the
        properties of the chemical elements are periodic functions
        of their atomic wieghts. ``In other words, if the elements
        are grouped in the order of their atomic weights, it will
        be found that nearly the same properties recur
        periodically throughout the entire series.'' The following
        tabular arrangement of the atomic weights shows the
        regular recurrence of groups (under I., II., III., IV.,
        etc.), each consisting of members of the same natural
        family. The gaps in the table indicate the probable
        existence of unknown elements.

     Note: A similar relation had been enunciated in a crude way
           by Newlands; but the law in its effective form was
           developed and elaborated by Mendelejeff, whence it is
           sometimes called Mendelejeff's law. Important
           extensions of it were also made by L. Meyer. By this
           means Mendelejeff predicted with remarkable accuracy
           the hypothetical elements ekaboron, ekaluminium, and
           ekasilicon, afterwards discovered and named
           respectively scandium, gallium, and germanium.
           [1913 Webster]
  
     Periodic star (Astron.), a variable star whose changes of
        brightness recur at fixed periods.
  
     Periodic time of a heavenly body (Astron.), the time of a
        complete revolution of the body about the sun, or of a
        satellite about its primary.
