2. The Laboratory 



A. Location of Laboratory. — It may be in a separate building, as the 

 home, but as a rule a corner room in the pharmacy is best suited for the 

 purpose. This room may be in the basement, or on the first, second or 

 other floor. Do not select a room with a through passage for obvious 

 reasons. It may adjoin a chemical or pharmaceutical laboratory, though 

 it should not be a part of such laboratories. Chemicals and chemical 

 fumes interfere with bacteriological and microscopical work. It should 

 have one door and two or more windows. There must be good light and 

 the environment should be favorable for bacteriological work, for which 

 reason a room in the basement is not, as a rule, desirable, , 



The walls and ceiling of this room should be absolutely plain and well 

 protected by white enamel paint. The floor may be cement, slate, or 

 hard wood, well oiled with boiled linseed oil, or it may be painted, or 

 covered with linoleum. The entire room (walls, ceiling, floor) should 

 be washed, scrubbed and disinfected from time to time. That is, it 

 should be kept bacteriologically clean. 



B. Furnishings. — All windows exposed to direct sunlight should have 

 white translucent roller shades. The laboratory should be well sup- 

 plied with gas; water, both hot and cold; and means for Ughting (gas, 

 electricity, acetylene). There should be just enough furniture and 

 shelving, no more. One table with slate top or lined with linoleum; one 

 stool, shelves for samples, apparatus and reagents. A case for chemicals, 

 cotton, culture media, etc. A case, with lock and key, for samples to be 

 examined. The plumbing must be of the best and the fixtures must be of 

 safe construction. The sink should be large and deep and should be lined 

 with porcelain and supplied with an ample drain board. A hood or ventila- 

 tor should be provided to carry off steam vapors. Near the table for 

 microscopical work should be a shelf or case for the works of reference. 



C. Apparatus. — There will be required: 

 (a) A good simple lens.
