The aim of our present communication should be to give you a brief account of the current photographic work on the Moon which the Manchester astronomers have been carrying out, for some time, from the French high-altitude observatory at Pic-du-Midi under the auspices of the United States Air Force‡. This work, today, includes a variety of lines of lunar studies but since the inception of the entire programme in 1958 our principal aim has been to secure adequate data for extensive three-dimensional topography of the surface of our satellite; and it is this work whose recent developments we should mainly like to describe to you today.
