Equations given by Wilson [Acta Cryst. (1988) A44, 478- 481] are corrected. There are misplaced brackets in equations (1) and (3) and an incorrect lower summation limit in equation (3). Equation (1) should read σ(θ1,θ2, θ3) = \sum_{\bf h} |FSh|2[(\sum_{i} cos 2π h . ri)2 + (\sum_{i} sin 2π h . ri)2] (1) and equation (3) should read σ(θ1,θ2, θ3, θp) = \sum_{\bf h} |FSh|2[(\sum_{i=1}^{n_{1}} cos 2π h . ri)2 + (\sum_{i=1}^{n_{1}} sin 2π h . ri)2] + \sum_{\bf h} |FSh|2[(\sum_{j=n_{1}+1}^{n_{2}} cos 2π h . rj)2 + (\sum_{j=n_{1} + 1}^{n_{2}} sin 2π h . rj)2].
