15050 STEVENSON (Alan, M.I.C.E., F.R.S.E.; uncle of E.L. S.) ACCOUNT of the SKERRYVORE 

 LIGHTHOUSE, with Notes on the ILLUMINATION of LIGHTHOUSES, with 33 steel plates, 117 wood- 

 cuts and diagrams, and folding map, impl. 4to. cl., with author's inscr., 12s (p. 3. 3s) Edin., 1848 



The third of the great triplet of early lighthouses which fascinated our youthful imagination the Eddystone, the Bell 

 Rock, and the Skerryvore, and in the wildest situation of them all. 



' It still remains a standard book ... He designed and carried out ten lighthouses, including Skorryvore lighthouse 

 tower, the finest example for mass, combined with elegance of outline, of any extant rock tower. This tower, which is 

 exposed to the full fetch of the Atlantic, is built on a rock 14 miles from the nearest land, the island of Tyree. The work 

 was begun in 1838, but a storm swept away the temporary barrack, and another had to be erected in its place. The 

 foundations of the tower involved the excavation of 2000 tons of material. . . . The tower rises to a height of 138 ft., is 

 42 ft. in diameter at the base, gradually decreasing to 16 ft. at the top.' D. N. B.

A description of the optical apparatus afterwards adopted for the Skerryvore Lighthouse. It was ' dioptric revolving, 

 the most complete apparatus which had hitherto been constructed. . . . Instead of Fresnel silvered mirrors below the 

 lenses Stevenson designed prismatic rings, which were introduced for the first time in this apparatus. . . . He intro- 

 duced prismatic rings above and below the central belts, thus securing equal distribution of light all round, and extending 

 dioptric action throughput the whole height of the apparatus. He also suggested the spherical mirrors placed on the 

 landward arcs of dioptric apparatus.' D. N. B.
