    cerci cause no symptoms; numerous cysticerci cause pain, tenderness and difficult movement. Diagnosis is possible only on excision of the subcutaneous nodules. In Stiles' collection of 155 cases, the localization was muscular in 20 per cent, and cutaneous in 3 per cent, (b) If they are in the brain (in 75 per cent, of Stiles' series) symptoms depend on their location; they are often absent; if the location is in the cortex, Jacksonian epilepsy is frequent, and if in the medulla, diabetes may develop, (c) There may be other localiz- ations. They may be found clinically in the eye (v. Graefe), and a few other localizations are found at autopsy, as pulmonary, renal, or hepatic. There is no treatment except surgery. II. Taenia Saginata (Mediocanellata). This form is most frequent in America, but is becoming more common in Europe. It is the fat tapeworm/' the unarmed, or beef tapeworm. Its cysticercus is found in masseters of beef, nearly seven times as frequently as in other muscles, or in the heart, or brain. They Fig. 86. ^^°- ^■^- are not so readily seen w^ith the naked eye as the cysticerci in pork. Ingestion of rare beef contain- ing cysticerci pro- duces the taenia sag- inata in man. The intestinal par- asite differs from the T. solium in the following points: (a) its head is larger, measuring 2 mm.and is square. It has no booklets but four sucking disks, which are larger, more forward and are surround- ed by pigment. (See figs. 83, 84, 85 and 86.) ib) Its neck is much shorter, (c) Its 'proglottides are longer (16 to 22 mm.) and broader (5 to 10 mm.), (d) The uterus con- tains 20 to 30 branches, which are less dendritic than pronged or forked, (e) The ova are rather longer. (/) The parasite is larger and longer, measuring 5 to 7 me- ters or yards. Its symptoms and treatment Head of Taenia saginata. (Eichhorst.) Toenia saffinata naturaK ze. (Af- ter Leuckart.)
