nesia in Saratoga ; of siliceous acid and carbonate of iron in 

 Sanel ; of silica in New Almaden, and of alumina in Calistoga. 



Adams has 304, New Almaden 112, Summit Soda 186, 

 Paso Robles No 1, 47, Paso Robles No. 2, 10 cubic inches 

 of carbonic acid gas in a gallon ; Sanel has an abundance ; 

 and Napa Soda has also an abundance, probably exceeding 

 any of the others. Paso Robles No. 1 has 10 grains of car- 

 bonic acid to the gallon, the only instance of determining 

 its quantity by weight. 



White Sulphur No. 1 has 6, White Sulphur No. 2 has 4, 

 White Sulphur No. 3 has traces, Calistoga has 3 cubic inches,

 which traces are found in the waters of Paso Robles, are es-
