The Sio and Haho, the two largest rivers of the coast region, both flow into the Togo lagoon.
Boetius was consul in sio, and his sons, while still young, held the same honour together (522).
Tschermak, in 1878, regarded them as isomorphous mixtures of the following fundamental molecules: H 2 KA1 3 (SiO 4) 3, corresponding with muscovite; Mg 6 Si 3 0 12, a hypothetical polymer of olivine; and H4S15012, a hypothetical silicic acid.
Clarke (1889-1893) supposes them to be substitution derivatives of normal aluminium orthosilicate A14(S104)3, in which part of the aluminium is replaced by alkalis, magnesium, iron and the univalent groups (MgF), (A1F2),(AlO), (MgOH); an excess of silica is explained by the isomorphous replacement of H 4 SiO 4 by the acid H4S130s.
The Sio and the Kapos or Zichy canal between Lake Balaton and the Danube is joined by the Sat-viz canal, which drains the marshes south of Sopron.
