Excerpt: ... COMBINATIONS Of MANGANESE AND OXYGEN: Protoxide of Manganese, (Mn) 27.7: Oxygen.(O) 8 Sesquioxide do. 27.7: do. 12 Peroxide do. 27.7: do. 16 Not yet discovered do. 27.7: do. 20 Manganic acid do. 27.7: do. 24 1 14 2 Permanganic acid do. 27.7: do. 28 J It will be seen that the fourth line in the above list is nameless, no combination having yet been discovered to complete the series. That a form of matter exists, and may yet be discovered, to fill the vacancy, is most probable. 35. Symbols and Equivalents of the Elementary Substances referred to in this work: NAME. SYMBOL.

But it will be seen in the table that some substances haye a small letter added to the capital; the necessity for vhia addition is easily explained. The symbol of Carbon is C, but Calcium (the Latin word for lime) also begins with C,--hence, to avoid all confusion in the symbols, Calcium is designated by Ca. In the same manner, N is the symbol of Nitrogen, and No of Natrium, or Soda. 36. Table of the principal Compound Bodies named in this work: HAMS. ELEMENTS. EQUIVALENT. SYMBOL. Sulphuric add, S 16.1.
