is four stories in height. The longer dimension of the building is east and west 

 —the entrance to the first floor being on the north side, and to the basement on 

 the south side. The material of the building is dark red vitrified brick, with 

 rustications of Roman brick and trimmings of Bedford stone. The building is 

 in form a rectangle, with only such projections as are necessary to relieve the 

 monotony of its exterior surface. The architect was instructed to make as many 

 windows as the character of the structure would permit, and the result is that 

 all the rooms are amply lighted. A feature of the construction is the character 

 of the partitions. There are two solid brick partitions running through the 

 whole height of the building. The other partitions are only two inches in 

 thickness, the necessary support being given by heavy pillars. These partitions, 

 a device of the architect, Mr. H. K. Holsman of Chicago, have a core of wood, 

 which is plastered solid on both sides. At first thought, they would seem to be 

 very unsubstantial, but as a matter of fact, after the adamant plaster is applied, 

 not only are the walls firm and substantial, but sound is not carried through them 

 to any disturbing extent. The manifest advantages of the partitions are the 

 economy of floor space and the fact that they are practically fire-proof. 



The building is finished in oak throughout, and while very plain, presents an 

 attractive interior. The total cost was about ^33,000. All the plun;bing is 

 " open." 



The laboratories for the department of biology are so located as to use north 

 light so far as possible. To that end, the room for museum purposes is on the 

 south side of the building, as shown in the annexed floor plan. A similar 

 museum room on the second floor is also devoted to the department of biology. 

 These museum rooms are not large, and were not intended for display purposes, 

 but mainly for the convenient storage of materials used in illustrating the lectures 

 of the department. A lift runs through the entire height of the building, and by 

 this it is easy to convey material from the second floor to the first, as it is 

 required for use. 



Between the museum and the lecture room is an apparatus room, or prepara- 

 tion room, which is used both in connection with the work of the museum and 

 in preparing material for lecture work. The lecture room, in the southeast cor- 

 ner of the building, has the floor raised in four steps, so that all students can see 

 the lecture table with clearness. The blackboard is a sliding one, and back of 

 it is a fixed plate of ground glass which can be used for illustrative purposes in 

 the lecture, or can be used in connection with the lantern work. The windows 

 are fitted with opaque shades, so arranged as to exclude the light, in order that 

 the room may be used for lantern work. 



Adjoining the lecture room, on the north, is the bacteriology room. This is 

 intended as a place where the various forms of apparatus connected with the 

 work in bacteriology can be permanently set up. The room is large enough, 

 also, so that small special classes in bacteriology can do their work there. 



The two rooms at the west end of the building are the general laboratories, 

 used for the more elementary work, and for the vertebrate work. They are so 

 arranged that by a movable screen the two rooms can be used separately or as 

 one large room for especially large classes.
