1. examined the rectus The myofibrils occasionally run a more complicated course and may penetrate the muscle fibre, coming to the surface on the other side. In these cases cross-sections show a variety of formations, for instance, the figure eight. Even so the muscle fibre is called a ringed fibre;Bucciante; Luria,1933
2. A large quantity of sarcoplasm at the periphery of the myofibrils within the same sarcolemmal tube oculi superior in 75 necropsy cases, and always saw ringed fibres in this muscle in subjects over 32 years of age. Wohlfahrt and Wohlfart;Wohlfart; found ringed fibres in a case of muscular dystrophy and one of dystrophia myotonica, and in the transversus perinei profundus in a patient not suffering from any myopathy,1935
3. vesicular nuclei, often with a prominent nucleolus, Bergstrand,1938
4. Ringed fibres have recently been described in the external ocular muscles by Siliotti;Perry, Smith,1954
5. mentions the occurrence of ringed fibres in one muscle biopsy fro'm a patient suffering from adynamia episodica hereditaria;Gamstorp;Bethlem; found ringed fibres in dystrophia The incidence of ringedfibres ana sarcoplasmic masses in normal and diseased muscle myotonica, and Berthrong and Griffith (1961) found them in muscular dystrophy. In 14 muscle biopsies from patients with various neuromuscular affections, ringed fibres were described by,1956
