Abstract
Attention is paid to the stereological estimator of the length density of l ineal features in three-dimensional space. In Gokhale (J. Microsc, (1990) 1 59, 133-141), the estimator based on measurements performed on a projection of the content of vertical slices with a given thickness Delta was derived . The aim of this paper is to show that using five vertical slices with sys tematically chosen orientations yields a reliable result, i.e. the bias of the estimator is smaller than In the case of a choice of the vertical axis such that most lineal features are not perpendicular or nearly perpendicula r to the vertical axis, a reliable result call be obtained using only three systematic orientations of vertical slices.
