tried to fulfill, so far as we understand pres- 

 ent needs and could foresee future ones. 

 Great praise is due to the architects, Messrs. 

 Cope and Stewardson, for aiming at utility 

 first, and for meeting as closely as possible the 

 requirements planned by the staff. 



The building comprises a full basement, 

 with three stories above it, and is thoroughly 

 fire-proof. The general form is that of a T, 

 the longest wing facing north with a length 

 of 216 feet. The shorter south wing connects 

 at the east with the vivarium building that 

 was erected in 1900. This gives a minimal 

 amount of hall space and all corridors, even 

 those of the basement, are amply lighted by 

 windows at their ends and by glass interior 

 doors. The main entrance is in the center of 

 the north fagade, and close to this main en- 

 trance is the main stairway. There is a second 

 entrance and stairway at the east end of the 

 main wing, a special freight entrance to the 

 basement at the south end, and near the last 

 an exterior fire escape. The type of architec- 

 ture is early English Renaissance; the walls 

 are of sand-moulded red brick, in a variety of 

 shades, laid Flemish bond. Base courses, 

 cornices and window-sill levels are of gray 

 Indiana limestone; the corners of the build- 

 ing are built of this stone, and doorways and 

 windows framed with it. All windows are ex- 

 ceptionally large and extend nearly to the 

 ceilings; those on the north front have in 

 each sash two panes of glass separated by a 

 half -inch air space, so as to reduce the cost of 

 heating. 



Above the third-story windows of the east 

 end of the main wing are inscribed the names 

 of Cope and Leidy, the great naturalists of 

 Philadelphia ; and on its north face the names 

 of Lamarck, Darwin, Huxley, Claude Bernard, 

 Johannes Mueller, Harvey, Aristotle, Mal- 

 pighi. Von Baer, Schwann, Reaumur, Cuvier, 

 Linnffius and Ray. 



All floorings are cement; this is covered 

 with terrazza in the corridors, with linoleum 

 in the library and lecture rooms, and with 

 maple in all private rooms and laboratories — 

 the cement being left in the breeding and 

 preparation rooms. Maple flooring is more 



durable than linoleum, does not splinter, and 

 with age grows continuously harder. 



The unit system of construction of rooms 

 has been fairly rigidly followed. Rooms are 

 only 20 feet deep. The largest laboratories, 

 each intended for 24 students, the largest 

 number a demonstrator can direct, measure 

 20X36 feet, and have three windows; a few 

 smaller laboratories, each intended for 16 stu- 

 dents, measure each 20 X24 feet and have two 

 windows; the private rooms for investigators 

 range from 20 X H feet to 20 X 1* feet and 

 have each one window. Each private room is 

 then one third the size of a large laboratory 

 unit. It was considered wisest to keep all 

 private rooms of these dimensions rather than 

 to build larger ones, so as to fully accommo- 

 date a considerable number of investigators. 

 The only exception is a large private room 

 (No. 301) for physiology, 20X24 feet. 

 These private rooms for the staff and investi- 

 gators are situated mostly on the north; 

 there are two of them (Nos. 113, 116) on the 

 first floor, six (N"os. 207, 218, 220, 221, 223, 

 225) on the second and seven (Nos. 301, 322- 

 328) on the third floor, a total of fifteen. Each 

 of these rooms has a window table two feet 

 wide extending the whole width of the room, 

 supported rigidly on iron brackets fitting into 

 the wall; and a sink in one corner next the 

 hallway. In addition there is a larger room 

 (No. 320) on the third floor to accommodate 

 several workers at once, with a continuous 

 window table on two sides. In each full-sized 

 laboratory there are three working tables, 

 each 4 X 13 feet, accommodating eight stu- 

 dents and placed at right angles to the win- 

 dows — an arrangement that prevents the 

 demonstrator from interfering with the light 

 of any student; in each table are drawers, and 

 lockers each large enough for a compound and 

 a dissecting microscope and dissecting trays. 

 The inner side of each locker door has two 

 shelves for bottles, and each microscope and 

 its parts bear the same number as the locker. 

 Each student receives a table area of two feet 

 by three and a quarter, one locker and two 

 drawers. In certain laboratories, as those for 

 histology and cytology, these tables contain
