ARRANGEMENTS for the jubilee celebrations of the Society of Dyers and Colourists, to be held at Bradford at Whitsuntide, are in active progress. Inaugurated at a meeting in Bradford on May 14, 1884, the Society is the oldest of its kind in Great Britain. Special interest in the celebrations will be attached to the issue early next month of a jubilee number of the Society's Journal, containing original articles by eminent authorities on the processes of dyeing and their development in the course of the past fifty years. In these, invention, scientific research and records of practical applications will receive full attention. It may be recalled here that the Society allots the Perkin Gold Medal at intervals, for conspicuous service to the tinctorial industries. By means of its award the synthesis of indigo, the discovery of viscose, of primuline, and of alizarine blue have been severally recognised.
