A partial course in Agriculture, occupying seven months in the winter, is arranged for the convenience of those who cannot pursue a longer course of study. Special students desirous to become proficient in some branch of Chemistry are also received in the Chemical Laboratory. In Natural History arrangements are also made for the instruction of special students, not candidates for degrees. The same is true in Practical Astronomy. No formal examinations are required for admission to these advantages, but they are only offered to young men who are able and disposed to be faithful in the pursuit of the courses they select. III. HIGHER COURSES LEADING TO THE DEGREE OF DOCTOR OF PHILOSOPHY OR OF CIVIL ENGINEER IN YALE COLLEGE. A higher course in Civil Engineering is arranged to follow the regular three years' course, and those who pursue it faithfully may receive the degree of Civil Engineer. (C. E.) Candidates for the Degree of Ph. Dr. must have taken already a Bachelor's Degree, and must pursue in this College, a course of two years' instruction in the higher studies of at least three departments of science, terminating with a satisfactory examination. PLANS AND DESCRIPTION OF SHEFFIELD HALL, OF THE SHEFFIELD SCIENTIFIC SCHOOL, YALE COLLEGE, NEW HAVEN, CONN. Sheffield Hall is situated in Grove street, fronting College street, nearly a quarter of a mile north of the College square. It is bui.t of stone and brick covered with stucco, and consists of a principal three story structure, and two wings (each of two stories,) now connected in the rear by another three story building. There are three public entrances on Grove street, of which the central one is the chief, leading to all portions of the building; the eastern door leads to the principal room of the Engineering Class and to the Metallurgical Museum above it; and the western door leads to the Chemical Laboratory. There are two projecting towers-one in front, at the main entrance, and one at the northwest corner of the building. The principal tower in front is ninety feet high and sixteen feet square. In the second and third stories are studies for two of the professors. Above these rooms is the belfry-clock with its four dials, and surmounting the structure is a revolving turret in which the equatorial telescope is placed. L, Closet.-P, Balance-room.-Q, Store room.-R, Chemical reagent room. The northwestern tower, sixteen feet square and fifty feet high, was built for the reception of a Meridian Circle. The extreme length of the edifice from the western tower to the east side is 117 feet; and the extreme depth is 112 feet. The three cuts which are given herewith exhibit the arrangement of rooms on each of the three stories. The basement, which is not here tepresented, contains a Janitor's apartment, and a metallurgical laboratory, in addition to the hot-air furnaces, store rooms, etc. The Observatory occupies the two towers, each sixteen feet square, recently added to the edifice. In one of these is mounted an EQUATORIAL TELESCOPE; in the other, a MERIDIAN CIRCLE, with a SIDEREAL CLOCK; both telescope and circle being the recent gifts of Mr. Sheffield. 9, Metallurgical Museum. 7, Recitation-room in Modern Languages, Mechanics, etc. "10, Agricultural Lecture-room.

The Equatorial Telescope, ordered of Messrs. Alvan Clark & Sons, of Cambridgeport, in November, 1865, was, early in October last, mounted in the revolving turret at the top of the front tower, some eighty feet above the ground, where it commands a good horizon. It is supported by a freestone pier, six feet in height, which stands on a massive floor of masonry arched in from the side walls, just above the tower clock. Though it thus partakes of whatever motion the tower itself is subject to, from winds and other causes, no noticeable inconvenience has been experienced, or is anticipated, from this source. The floor of the room, which is of wood, immediately above the stone floor, rests only in the outer walls, and does not touch the pier. The object-glass has a clear aperture of nine inches, and is nine feet ten inches in focal length. The tube, made of pine handsomely finished, and ten inches in diameter, is at once stiff and light. Seven Huygenian eye-pieces give powers ranging from 40 to 620. All but one of these fit also a diagonal eyetube containing a prismatic reflector. Another diagonal reflector-the first surface of an acute prism of glass-is used in observing the sun, the greater part |
