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 a 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.

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

• THE PRESIDENT OF THE UNIVERSITY.

• THE RECTOR OF THE UNIVERSITY.

• MR. ROBERT H. MC CORMICK, JR.

• MR. LYMAN B. KENDALL.

• PROFESSOR E. C. PICKERING, DIRECTOR OF THE HARVARD COLLEGE OBSERVATORY.

• THE DIRECTOR OF THE LEANDER MC CORMICK OBSERVATORY.

A temporary students' observatory, erected in the rear of Dawson's
Row, is intended primarily for the use of students in Astronomy B1.
