**tangent**sight (designed by Major-General William Millar) was introduced into the navy; this was adopted by the army in 1846. - As the
**tangent**sight was placed in the line of metal, hence directly over the cascable, very little movement could be given to it, so that a second sight was required for long ranges. - I it will be seen that in order to strike T the axis must be directed to G' at a height above T equal to TG, while the line of sight or line joining the notch of the

**Tangent**Sight. - Amount of left deflection given - the amount can easily be determined thus: The height of
**tangent**scale for any degree of elevation is given with sufficient accuracy by the rough rule for circular measure It= X 1200 where a is the angle of elevation in minutes, h the height 3 of the**tangent**scale, and R the sighting radius; thus for 10 h _ 60 X R _ 2.0 Now supposing the sight is inclined I° to the left, 3600 - which will move the notch from H to H' (see fig. - Other improvements were: the gun was sighted on each side,
**tangent**scales dropping into sockets in a sighting ring on the breech, thus enabling a long scale for all ranges to be used, and the foresights screwing into holes or dropping into sockets in the trunnions, thus obviating the fouling of the line of sight, and the damage to FIG. - The

**tangent**sights have been improved in details, but the principles remain the same. - Except for some minor differences the
