The Leander McCormick Observatory is situated upon Mount Jefferson,
which furnishes an unobstructed horizon. The principal building is a rotunda
forty-five feet in diameter, which contains the great Clark refractor of twenty-six
inches aperature. The instrument and building are the gift of the late Leander
J. McCormick, Esq., of Chicago. The telescope is fitted with micrometer, photometer,
and plate-holder for stellar photography. The computing rooms adjoining
contain clocks, chronograph, machines for measuring astronomical photographs
and spectograms, and an excellent working library. In a smaller building
are a three-inch transit and a six-inch equatorial. A temporary students' observatory,
erected in the rear of Dawson's Row, is intended primarily for the use of
students in Astronomy B1.

The members of the Visiting Committee of the Leander McCormick Observatory
are:

• THE PRESIDENT OF THE UNIVERSITY.

• THE RECTOR OF THE UNIVERSITY.

• MR. ROBERT HALL MCCORMICK.

• MR. LEANDER MCCORMICK-GOODHART.

• PROFESSOR S. I. BAILEY, HARVARD COLLEGE OBSERVATORY.

• THE DIRECTOR OF THE LEANDER MCCORMICK OBSERVATORY.
