Introductory Treatise on the Lunar Theory e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I may add that the cooperation of the officers of the University Press has made it possible for me to see the printing almost completed during my temporary residence in Cambridge, and thus to avoid the delays and difficulties which would otherwise have arisen.
