Emily Dickinson Lexicon

COL-LI-MA'TION, n.¹ [L. collimo; con and limes, a limit. Ainsworth suggests that it may be an error, and that collineo, con and linea, is the real reading; but collimo is in perfect analogy with other words of like signification. To aim, is to direct to the limit or end.]

The act of aiming at a mark; aim; the act of leveling, or of directing the sight to a fixed object. – Asiat. Researches.
