But there is another need. The step between the University laboratory and the Works laboratory is a long one. Discoveries do not leave the man of science in a form which can be at once assimilated by the engineer, the shipbuilder, or the manufacturer. Some means are needed to make them available to such men, to secure for them the advantages which come from the growth of knowledge by which alone they may keep in the forefront of their trade.
