Lacaille - +019,-400: A beautiful and nearly circular crater, 35 miles in diameter. The walls are highest on the west, where they are also broad, and contain a crater, D. The south-west wall contains many little craters, and there is a larger crater on the south-south-east. On the north-east is a small crater, from which a valley runs northwards, opening into a large enclosure, T, which is full of hills, and also contains some craterlets. There is a large elongated crater, B, on the north wall. In the interior of Lacaille are some hills and craterlets, and two shallow depressions, one on the south and the other on the east.- Wilkins and Moore, The Moon, Faber & Faber, 1955
