ifj. Finály István dr.: The chemical composition of the mineral water of Simontornya

70 Dr. S. S. Finály Even the above few data show that almost all borings of the close or farther lying localities yield relatively soft waters containing about 300—600 mgs solid matter, no sulfates and somewhat more chlorides than usual. The high values for bicarbonate hardness affirm that most of them have an alkalihydrocarbonateous character. The comparison of the Simontornya mineral water with others known in Hungary leads us to the conclusion that the mineral waters of Harkány and Lipik show some similarities in their chemical character. The following table compares the respective data as millival per cents of the more important ions contained by the mineral waters in question.

The chemical character of the above mineral waters is, however, quite similar to each other all belonging to the group of alkalihydrocarbonate containing ones as dominant salts. I can yet add that sometimes a slight precipitate (consisting probably of ferric hydroxyde) was observed on the bottom of glass
