The fundamental work on this translation was done by Miss Francis M. Svaldi, a student working on National Youth Administration funds. After Miss Svaldi\u27s graduation, her work was revised and corrected by James R. Naiden, Special Research Assistant in Astronomy (now 1st Lieutenant Army Air Corps), working under the direction of C. C. Wylie, Professor of Astronomy. The pressure of war work, and the enlistment of Mr. Naiden in the Armed Forces, have made it impossible to smooth out the translation as planned. However, it has been thought best to publish it in its present form, since it is not known when further work will be possible. The language of Schiaparelli is unusually full, and very precise. In this translation, such a precision would have appeared exaggerated, and an occasional word or phrase has been omitted to enhance clarity
