1778. Neeve's instrument for transferring angles (fig. 419.) is formed of a piece of deal about two feet long; a is the flat side of the instrument; b, the edge; c, the short leg removed from the lone leg; d, the edge of the short leg; e, part of the long leg, showing the quadrant; g h i form a diagram, showing the mode of using the instrument. Supposing it were required to draw an angle of forty-five degrees from the point f on the line g h: place the short leg parallel with the line, so that the long leg touches the given point, then draw the line i f. If you require a perfect triangle, turn the instrument over, draw a line along its side, and the triangle will be completed; each side of the instrument being alike in length, and perfectly flat.
