or by steam, of the most recent construction, some ofthem not yet finished; consisting of-

1. A series of sailing ships of all classes, from the“Queen”—a first-rate man-of-war—to a brig of 10guns (146, p. 344, and illustration).

2. A series of screw-ships of various classes, fromthe “St. Jean d’Acre, ” of 100 guns, to a sloop of 12guns.

3. A series of experimental frigates.

4. A series of experimental brigs.

5. Models of bows and sterns.

G. Transverse sections.

The Admiralty, by the comparative trials they haveordered, have contributed in a very high degree to themost recent progress of naval architecture. They haveequally contributed to the progress of hydrography, as Ishall explain when speaking of the maps presented to theExhibition, which are included in this award of theCouncil Medal.

2. To Sir William Snow Harms (150, pp. 345,346, andillustration). Science and humanity proclaim the meritsof Sir W. Snow Harris ’s inventions He has exhibitedpractical models of his system of attaching lightning con-ductors to the masts or hulls of ships, which has been forseveral years in general use in the British Navy .

As a means of preserving life and property from theeffects of lightning, nothing has proved more completelysuccessful and effectual than these conductors. Thetransmission of the electrical discharge from mast tomast, and finally from the conductors in the hull to theM ater, is perfectly effected under all circumstances, andin every position of the spars or of the ship when pressedby sail, and without demanding any care or attention onthe part of the officers or crew. The mechanical arrange-ment of the plates forming the conductor, which is ofgreat capacity, is such as to admit of their accommo-dating themselves to any flexure the spars can sustain,whilst at the same time they preserve a fair and conti-nuous conducting line. The various branches or subdi-visions in the hull allow of a free dispersion of the elec-trical agency in all directions to the bottom of the ship,and into the sea, by which the tension in any one pointis so reduced that explosive action is next to impossible.For these reasons a Council Medal is awarded to Sir W.Snow Harris .

3. To llis Grace the Duke of Northumberland (136,pp. 342, 343).—To the humanity of His Grace the Dukeof Northumberland, to his unbounded liberality andgenerous encouragement of practical science, we owe thenumerous efforts of able men to construct life-boats cal-culated to meet the perils of an ocean tempest. Theymust he easy to manage, in order to accomplish the greatobject for which they are designed, viz., the saving oflife and property endangered by shipwreck. Ilis Grace,■with this philanthropic view, has expended some thou-sands of pounds in obtaining for the coasts of Northum-berland, an improved class of life-boat, designed andbuilt in consequence of the premiums the noble Duke hasoffered. Models of these very boats figure amongst themost valuable contributions to the Great Exhibition , andfurnish a splendid example of liberality in the cause ofhumanity and practical science never surpassed, if everequalled. Such are the motives under which we havejudged Ilis Grace the Duke of Northumberland worthyof receiving the Council Medal.
