The polar compression of the planet was also measured and appeared to be greater than that indicated by theory, which may be due to an excess of clouds in the equatorial regions. The presence of the dark and narrow streaks, called canals by Schiaparelli, has been confirmed, and various measurements of them have been made. The clouds projecting beyond the limb and terminator have been studied, and their height has been found to be at least twenty miles...
...large apparatus at Cambridge has been the atmospheric conditions. In Peru, however, the atmospheric conditions are most extraordinarily favorable for the study the heavens; although the chief object of the recent very successful expedition to Peru by Prof. W. H. Pickering was the photographing of the planet Mars, yet the careful visual observations were made at the same time which have led to most interesting results. Another event of this visit was the construction of a meteorological station on Mount Chaehacari in Peru at the height of 16,000 feet, 1,000 feet higher than Mt. Blanc and hence...
