"A small town and parish of Edinburghshire. The town stands on the left bank of the North Esk, but includes the suburb of Westmill in Cockpen parish, with which it is connected by a substantial stone bridge."
"Lasswade parish is bounded N by Colinton, Liberton, and Newton, W by Glencorse, S by Penicuik and Carrington, and E by Cockpen, Newbattle, Dalkeith. Its greatest length, from NNE to SSW, is 7 1/3 miles; its greatest breadth is 6 miles, but its average breadth is little over 3 miles; and its area is 10,678 acres. A projecting wing at the NW extremity is occupied by the E end of the Pentland Hills, presenting partly heath and partly good pasture; and in the S, a district of bleak and unsheltered moorland, including some of the northern declivities of the Moorfoot Hills, stretches for about 2 miles into the interior. The surface on the whole declines rapidly from the border towards the SE, and consists of rich and well-cultivated plain, finely wooded, and of picturesquely diversified scenery."
