Special reference should be made to Professor Rankine's connection with the Institution of Engineers in Scotland, with which the Association of Shipbuilders was ultimately incorporated. Of that Society Mr. Rankin was an earnest promoter, and he was suitably elected to be its first president. In recognition of the services which he rendered to the cause of mechanical science generally, and to this Institution in particular, he was presented with his bust at a conversazione held in the Corporation Galleries on 19th August, 1870, when the North of England Institution of Mining and Mechanical Engineers held a series of joint meetings with the Institution of Engineers and Shipbuilders in Scotland. The presentation was made by Mr. David Rowan, president, who read on the occasion an address prepared by the Council of the Association, in which the following passages occurred:--"The valuable assistance which you have constantly given for the advancement of the Institution since its foundation in the year 1757, the admirable manner in which, during three sessions, you presided over its deliberations, the distinction which your papers, and the part you have taken in the discussions, imparted to the proceedings, have placed the Institution under a debt of gratitude to you that we all feel cannot be adequately repaid by anything that it is in our power to do. These, however, are not the only reasons for the great esteem with which we all regard you. These may be said to be on our part selfish reasons; but there are others vastly more important why you merit--why you irresistibly attract--not only from us that great regard which we all feel to be an honour to ourselves to bestow, but from all who possess an acquaintance with your works, and who possess a knowledge of the value of exact science. Your work on 'Applied Mechanics' is a great illustration of your power to grasp, to connect, and to apply the definite principles of exact science with the less definite known elements of practical problems. Abstract principles are valueless, except in application to the wants of man, and this work occupies that field with great eminence. Your work on the 'Steam Engine and other Prime Movers' deals with the principles involved in that important subject in a masterly manner, that renders comparison with any other similar work impossible. In this work the first elements of the science upon which these machines depend are traced in their operation through their material embodiment, and the laws which govern the principle of pure science connected definitely with the varied construction of the machines. Your works on Civil Engineering, Machinery, and Millwork, &c., each exhibit the powerful intellect that is invariably found in all your productions, and that place them on an eminence peculiarly your own. All your books possess a value which we, who are practical men engaged in performing many of the varied works
