Lunar photography with the Hooker Telescope

My justification for contributing to this symposium is certainly not that of special knowledge. I cannot pretend to have made any serious study of the Moon, and therefore my comments on lunar research are entitled to but little weight. But I could not forego the privilege of joining in this tribute of admiration and respect for the work of my friend Professor Brown, whose fundamental investigations on the motion of the Moon have so richly deserved the award of the Bruce Medal.
