Evection: The second inequality of the moon, which vanishes at new and full moon and is a maximum at first and last quarter.
"Kepler"
Walter W. Bryant
The Evection, an irregular motion of the Moon discovered by Ptolemy, whereby her mean longitude is increased or diminished, was explained by Horrox as depending upon the libratory motion of the apsides, and the change which takes place in the eccentricity of the lunar orbit.
