A Summary of Planetary Work at the Lowell Observatory and the Conditions Under Which It Has Been PerformedDouglass, A.E. January 1899 (has links)
In accordance with the title, the present paper divides itself into two parts, of which the first wil1 be a brief resume of the planetary work done here, with a few details and announcements which have not heretofore been given to the public, and the second will present the writer's personal opinions of why it has been possible to reach these results. The latter must necessarily be more in the form of suggestions than facts, for to give facts one must have tried personally many widely separated localities over long periods of time.
