Abstract
Instrument for the edition of heights by means of which all the visible heights to be measured can be determined with precision, because it constitutes an application of one of the trigonometric relations proper to the right triangles, according to which one of the sides of the right angle of a right triangle is equal to the tangent product of the angus opposite to that side of the right angle.
