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 aperture. 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 spectrograms, 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.
