PLANNING AND EQUIPPING OF A COSMETIC LABORATORY •99,5 was quite clear that to get to the various parts of the laboratory the main corridor must be on one side of the stanchions. With a corridor 200 ft. or so in length, even a width of 6 ft. would create a tunnel-like effect if it were completely partitioned and this, in my view, would be psychologically xvrong. To solve this problem, what one might call the main laboratory has been planned as a completely open one. The benches are of such a length (approx- imately 14 ft.) that they leave a 6 ft. gangway on the southern side of the stanchions. This means that the passage is a part of the laboratory and it is, therefore, being used to a maximum instead of being merely for getting from one place to another (Fig. 3).

The effect of this is shown quite well when one examines those rooms which, by their very nature, demand that they should be partitioned off. For example, in the physiology, histology and bacteriology laboratories, xvhich is one laboratory partitioned into three portions, the effect of putting in the partitions shows how much more space has to be employed for walking about. Indeed, in the biochemical laboratory, which is partitioned off partly to prevent malodours permeating the general laboratory but more to make sure that the atmosphere within the biochemical laboratory itself is clean, leads to a very short bench and a necessity for employing wall benches which, in my view, are not very good design, notal•l•, because of the right angle bends in the corners of the room.

226 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS The northern side of the laboratory, which, allowing for the stanchions being a foot thick, is 20 ft. wide, had in some instances to be partitioned off, and where possible this partitition took the form of cupboards with sliding glass doors at the top and wooden sliding doors below. These are all shelved and act as storage space for apparatus and chemicals which is then of easy access to the open laboratory (Fig. 4). This method of employ- Fig. 4. Storage Shelves in Laboratory. ing the space between the upright stanchions gives a 300 ft. run of shelving 8 inches wide and about 200 ft. run of 11 inches wide shelves. Already in the short space of time the laboratory has been working the usefulness of this form of design has been fully proved. Mention might here be made of the shelving fitted at the ends of the benches. These are to hold the various bench reagents which are normally placed on a central superstructure. In the same way, the balance rooms were positioned at two convenient places opening into the main laboratory and of easy access to all the workers in the main laboratory and the special service ones.
