Abstract
Progressive school teachers as well as university workers and industrial chemists will be interested to learn that a company, known as Crystal Structures, Ltd., The Broadway Works, Farnham Common, Buckinghamshire, has recently been formed to manufacture crystal structure models. It is intended later to undertake the manufacture of various types of models, employing a considerable variety of materials, but at present production is confined to one-inch, drilled, wooden balls separated by metal spokes which indicate the co-ordination. The colours used conform to the recommendations of the X-ray Analysis Group of the Institute of Physics. In addition to a standard set of models for teaching or museum display, a set of fifty loose spokes and balls drilled along the twenty-six axes of symmetry of the cubic system are available for students to build models for themselves. Individual models can be made to order. It is claimed that errors of construction do not exceed 4 per cent in the dimensions of the unit cell, and the direction of the spokes is correct to within 2°. Inquiries may be made to the Works or to Dr. Nora Wooster, Brooklyn Crystallo-graphic Laboratory, Cherry Hinton Road, Cambridge.
