COLLIMATION 61 COLLINS chairman of the Extension Committee of the Red Cross at Cayuga co., N. Y., and took part in the war-loan campaigns. He wrote several works on legal subjects, including "Collier on Civil Service Law (1901); "The Trusts" (1900); and "The Law and the Higher Law" (1918). COLLIMATION, the act of aiming or pointing toward any object. ^ The line of CoUimation of a telescope is that from the optical center of the objective to the middle wire, or to the mean of the wires of a transit, or to the zero-position of the micrometer-wires in an instrument for measuring zenith-distances. The Error of CoUimation of a transit is the departure of this line from a direction at right angles to the axis. The Col- limation Correction is the amount to be applied to the observed times of transit to correct them for this error. COLLIMATORS, telescopes used for the determination of the corrections of collimation, for flexure, or for the zenith- point of a meridian-circle or transit. They are generally fixed upon piers N. and S. of the instrument and pointed toward each other and toward the in- strument itself when in a horizontal po- sition. They are adjusted so as to be intervisible when the instrument is lifted out of its Y's, and, on looking into either, the wires of the other are seen alongside those in the field, so that they can be pointed on each other, or the instrument itself upon either in turn. Besides the above arrangement there are many others, and also other uses of Collima- tors. Very often a long focus lens with a distant meridian-mark takes the place of one of the Collimators, and it is then used also as a reference point for the azimuth-correction of the instrument.
