windows in the partitions for light, and will have neat 3 hy 4-inch black walnut hand 

 rails, supported by iron elbows. 



The principal rear stairs, about twenty-three feet (23 feet) in height, of rise and of 

 the form and dimensions shown on plans, will be finished in a manner exactly simi- 

 lar, and of the same materials and workmanship, as the principal front stairs described 

 above. 



Staircases in campanile tower. — The interior of the campanile tower will be eleven 

 feet (11 feet) square, and will be occupied, at the level of the museum floor, with a 

 staircase having steps four feet (4 feet) in width, and a well three feet square in the 

 ■centre. This staircase will lead from the ground floor of the museum to its gallery, 

 and have steps, risers, balusters, newels, coves, brackets, &c, of a similar character 

 to the principal stairs above specified. Above the level of the gallery floor a small 

 stairway two feet six inches in width will be carried in flights, per direction of archi- 

 tect, to the upper story of the tower. The stairway will be partitioned off from the 

 tower by joists, and in the partition, doors will be framed and set to communicate 

 with the two upper stories of the tower. 



Staircases of octagonal tower. — A winding staircase with steps three feet in width, 

 having a clustered column in the centre, will lead in this tower from the floor of the 

 library to the gallery. The steps will be supported against the wall and the central 

 column by iron stringers, and the hand rail will be of black walnut. The sides of 

 the tower will be wainscoated up to the under side of the hand rail, and the central 

 column will be formed of clusters of circular columns of wood. The wainscoat and 

 columns will be painted four coats, and column sanded to represent marble. A hand 

 rail of black walnut, supported on handsome iron elbows, will be carried around the 

 column. The ceiling of the octagonal tower over this staircase will be groined. A 

 staircase, similar in all respects, and similarly furnished, will lead from the floor to 

 the gallery of the museum. Above this line a smaller staircase will be carried to the 

 summit of the tower. All the treads and risers in these stairways will be of the best 

 yellow pine. 



On each side of the rear entrance to the museum a flight of steps three feet wide 

 will lead from the ground floor to the gallery, with balusters, rails, arches, trefoils, 

 newels, coves, and brackets, similar to those of the principal front stairs. 



The stairs to the chemical lecture-room and its gallery will be placed in the porch 

 on the eastern end of the chemical lecture-room wing. They will consist of two 

 flights : one in the porch, leading level of the porch floor to that of the chemical 

 lecture-room floor, and one in a double flight, landing from the latter level to the gal- 

 lery. The latter will have steps, coves, newels, balusters, arches, &c, similar in 

 character to those of the two principal staircases, but of smaller horizontal dimen- 

 sions. Beneath the latter stairs a flight of steps will lead from the level of the chemi- 

 cal lecture-room floor to the floor of the basement beneath it. These will have risers 

 and treads of yellow pine, and plain octagonal newels five inches (5 inches) in diame- 

 ter. The balusters will be octagonal, two inches (2 inches) in diameter, with 8 by 4- 

 inch rails, all of black walnut. 



The stairs in tower of west wing will be square, filling the whole of the tower, and 

 will be carried first to a level with the floor of the first story, and then to the top of 

 the side aisle arches, with handsome octagonal balusters two inches (2 inches) in 

 diameter, with semicircular arches between those of the same finish, &c, as the two 

 principal staircases, with a square newel handsomely carved, and a 3 by 4-inch 

 moulded hand rail, all of black walnut. The sides of the tower will be wainscoated 

 to the height of the hand rail. 



The private stairs to Regents' room, lecturers' room, and muniment room, will be 

 in the small octagonal tower attached to the central rear tower. They will be car- 

 ried from the level of the surface of the ground, to the third story of the tower, or 

 muniment room, a height of about seventy feet, (70 feet.) They will wind around 

 a column from 8 to 12 inches in diameter, and will have treads and risers of yellow 

 pine, and a handsome moulded hand rail, 3 by 4 inches, of black walnut, secured to 

 the walls by iron elbows. The walls will be wainscoated, on end, with black walnut, 

 as specified in former instances, to the height of hand rail. 



Laboratory stairs. — Private stairs, with steps three feet in width, having octagonal 

 balusters two inches (2 inches) in diameter, and 3 by 4-inch moulded rail, of black 

 walnut, will be carried from the ground floor of laboratory, at the end of the chemi- 

 cal lecture-room, to the second floor. A flight of stairs, also three feet (3 feet) in 

 width, will be carried from the first story of the east connecting range to the second 

 story of the same, a height of about thirteen feet. They will be partitioned off with
