Part III. — Eleventh Annual Report 



in the same fibre, and the various fibres varied considerably in width. 

 Sometimes the coloured portion was stained much more deeply at its ends 

 than in the middle. The rods are usually cylindrical, but moniliform 

 rods with deeply-staiuetl swellings are present. The rods are quite 

 irregularly arranged, and, though usually fairly straight, have in some 

 cases a crooked form. They lie in bundles surrounded with spores, or 

 end to end at any angle to each other. Spore formation appears to take 

 place by the collection of all the protoplasm to one end of the rod, where 

 it becomes spherical. There is no appearance of fructifications bearing 

 numerous spores. On teasing the skin these bodies were isolated and 

 stained with various reagents. The staining portions invariably took up 

 stains very deeply, the non-staining portions alternating with them some- 

 times showed a faint colour. As the fish was only obtained when dead, 

 it was impossible to make cultivations of the fungus. 



5. A Cod with One Eye. By George Sandeman, 

 St Andrews Marine Laboratory. 



A cod was brought in with only one eye. The orbit of the other 

 was covered over with quite normal skin, lying level with the edges of 

 the orbit. The skin was adherent at one point, answering to the middle 

 of the eye. Below it was a large mass of cicatricial tissue radially 

 arranged round the point at which it adhered to the skin. This fibrous 

 tissue was very dense at its external surface, but became looser towards 

 the interior. It was gritty to the knife on cutting. Imbedded in the 

 connective tissue was a saucer-shaped mass of bone, circular in outline, 

 answering to the base of the sclerotic. It was directed in the axis of the 

 orbit, and had pigment in the tissue on its distal surface. Passing 

 inwards from it was a fibrous chord, which represented the remains of the 

 optic nerve. This disappeared entirely within the skull, and the optic 

 nerve, when traced from within, was not joined to it, but ceased its 

 course before reaching the foramen. A curved piece has been removed 

 from the frontal bone, and its place supplied by dense connective tissue. 

 There is a slight amount of asymmetry as a consequence of this old 

 lesion. The side of the mouth under the blind eye — viz., the right — is 

 lower than that on the functional side, but the bones of the skull appear 

 equal on both sides. Yet, on looking along the median dorsal ridge of 

 the skull, it is evident that the whole structure has a slight turn over to 

 the right side, so as to raise the functional eye.
