Treatise on Astronomy 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. It is difficult to be original in an elementary work, and on a subject which has occupied men's thoughts from the earliest times. The Author's aim has been rather to convey clear and distinct ideas than to affect originality; and it is hoped that where he has deviated from the beaten track it has been at no sacrifice of simplicity.
