PLAN OF THE BUILDINGS. 15 



PLAN OP THE BUILDINGS. 



The buildings were divided into a main laboratory structure, 

 facing toward the south and divided into two symmetrical portions, 

 the one on the east for the biological and the one on the west for 

 the chemical laboratory. 1 The power house was placed to the rear 

 and connected with the main structure by means of a corridor, and 

 in addition to the space for the boilers and engines it provides room 

 for the serum laboratory. 2 



The whole structure, therefore, is in the form of the letter T, 

 that portion of it in which biological and chemical work is carried 

 on being so planned as to give the minimum of direct sunlight a 

 great desideratum for microscopic work. Bisecting the main struc- 

 ture lengthwise are three corridors 10 feet wide and 236 feet long, 

 the one in the foundation being for the purpose of giving access 

 to all the pipes leading from the power house and to provide space 

 for the storage battery. The two upper hallways are the main 

 passageways of the building and all of the rooms open on them. 

 The eastern half of the structure is devoted to biological work with 

 the exception of the space occupied by one room (Xo. 10) for 

 storage of apparatus and another for offices (Xo. 13). Passing 

 through the main entrance and turning to the right, the disposition 

 of the rooms is as follows: Xo. 12 for the preparation of culture 

 media for biological work, Xo. 14 for botanical work, Xo. 18 as a 

 storehouse for botanical duplicates, Xo. 19 a mechanic's room, 

 Xos. 17 and 15 for bacteriologic diagnosis and research. On the 

 upper floor in the same order Xo. 116 is for the photographer, 

 Xo. 118 for the pathological museum, Xo. 120 for pathological 

 work and research, Xo. 122 for incubators and refrigerators, Xo. 

 124 for entomological work, Xo. 121 an outdoor laboratory for the 

 entomologists, Xo. 119 a laboratory room for bacteriological and 

 pathological research, Xo. 117 for biological research, and Xo. 115 

 as an office for the Director of the Biological Laboratory. Turning 

 to the left from the entrance way on the ground floor, room Xo. 8 

 is for the storage of chemicals and apparatus ; Xo. 6 as a laboratory 

 for organic chemistry in connection with drugs, medicinal plants, 

 and natural products; Xo. 4 for a commercial laboratory in chem-
