The second floor contains the library, the physics lecture room and apparatus room, and several recitation rooms and offices. The library is a branch of the main library of the College and is open to all students, who are at liberty to consult and take out such books as may be needed in their work. No librarian is in attendance, but each student records the taking out and return of a book from the room.

The physics lecture room is the largest class room on the Hill, but it is filled whenever the three divisions of Physics I meet together for a lecture. Here also are held the meetings of the Engineering Society. The physical apparatus room is something of a curiosity shop. In addition to the apparatus now used for lecture room experiments, it contains many articles of historic interest, especially in the line of early forms of electric lighting and telephone apparatus.
