Dendrometer (δένδρον, a tree, and μέτρον, to measure), an instrument for measuring trees, invented by Duncombe and Whittell. It is fitted to a theodolite, and may be used either with or without it, as occasion requires. Its principal use is to measure the length and diameter of a tree, perpendicularly or obliquely to a horizontal plane, or in any situation of the plane on which it rests, or of any figure, whether regular or irregular, and also the length and diameter of the boughs, by mere inspection. The inventors also calculated tables, by the help of which the quantity of timber in a tree may be obtained without calculation or the use of the sliding rule. Roger's dendrometer is an instrument for the same purpose.
