the use of some clip or locking device rather than wood screws in the end gables. The inside of each drawer, if made square, would accommodate similar sized partitions in both directions. One suggestion was to make the base unit exactly 2 feet square. This would allow a more modular treatment of the units, but would lead to a considerably higher cost per square foot of bench top. It is advisable to keep the depth of the bench tops to 2 feet or less in order to use standard 4-foot materials in their manufacture. These improvements, together with others, all tend to increase the utility of the cabinets, but in no way change the original design of the furniture unit. A description of the design of this new type of laboratory furniture would not be complete without mentioning other associated pieces which helped to complete the balanced laboratory plan. There was a 4-foot sink unit with an Alberene stone top. A 3-foot corner cupboard unit was required in some of the laboratories. Two- and 3-foot table units, each with a single drawer and no legs, but fastened between base units, provided space at any height for sedentary work, as well as for storage of laboratory stools. Other units included 6-foot laboratory tables, wall and floor cases with sliding glass doors, and small single-pedestal desks for senior technicians. Comments on this new design have been favorable and visitors to the Building Research Centre have been very much interested in its suitability to the wide variety of work being undertaken by the division. Acknowledgment
N e w s h a p e i n c r e a s e s stability, s p e e d a n d e a s e of h a n d l i n g . With this new polygon-shaped platinum crucible Baker research and development make a major contribution to better laboratory techniques. The polygon crucible has been tested in actual laboratory applications and found far more useful and efficient. It retains its shape indefinitely, and is available with or without reinforced rim, in all standard sizes. The flat sides of the polygon extend only part way down; the balance is circular. Baker offers industry the most complete line of platinum laboratory ware, including all standard equipment, and facilities for custom manufacturing any special equipment required.

The authors are indebted to the staff of the Division of Building Research for their helpful criticism of both the preliminary and final designs. They were fortunate in having available a set of furniture specifications which had been prepared by another division (Applied Chemistry) of the National Research Council. These specifications were veryuseful as a reference and a guide, although the actual design was different. The specifications prepared for the new furniture described only the over-all appearance, size, quality, and function of the various unit types. The actual constructional details were worked out by the manufacturer, Spanner Products of Toronto. Special thanks are here recorded to Paul Ryley and Russell Spanner of Spanner Products. Many of the manufacturer's suggestions were incorporated in the final design. In this way the knowledge and skill of the furniture craftsman became part of the finished product. ANALYTICAL
