Abstract
PROGRESS in nearly every branch of scientific investigation is dependent on the provision of suitable measuring apparatus. As the science develops, an ever-increasing degree of accuracy of measurement is required, which in its turn involves a correspondingly higher degree of refinement in the measuring apparatus. Many of the measuring instruments employed are essentially of an optical nature, and thus the optical instrument maker has been truly described as the tool-maker for all branches of scientific investigation including his own. It is the function and the duty of such a tool-maker to keep himself familiar with the latest advances in science, so as to be able to understand or even to anticipate the requirements of the investigator, and to meet these requirements by the provision of suitable practicable devices. That the British optical instrument maker has successfully fulfilled this function was clearly indicated by Mr. F. Twyman, who, in his recent presidential address to the British Optical Instrument Manufacturers' Association, discussed the capacity of the industry for invention, development, and production. His survey contained a record of notable achievements in regard to instrument design and construction of which any body of workers might justly be proud.
