For instance, in the Poland spring-water the total solid contents amount to less than four grains to the gallon (0.06 gram to the liter); and at the Hot Springs of Arkansas some of the waters contain less than ten grains to the gallon (0.15 gram to the liter). Many other waters from widely separated localities might be cited, but these are well known and will suffice to prove the point. Illustrations Three cases will suffice to illustrate the applicability of the scheme: The High Rock Spring and most of the other springs at Saratoga would be described as carbonated sodic-muriated alkaline-saline springs; i. c, the water contains free carbonic acid gas, its predominant solid constituent is sodium chlorid.but it also contains alkaline carbonates. It belongs to Group A, as no temperature is given, it being a cold spring. The water of the Gilkoy Hot Springs of California would be described as a hot sulphocarbonated sodic-muriated saline water; i.e., it contains both free carbonic acid gas and free sulphuretcd hydrogen, and its principal solid constituent is sodium chlorid. It belongs to Group R, as it is a hot water. A third example is the Hot Spkings of Virginia. The water of the Boiler Spring, one of its many springs, may be described asa hot carbonated calcic alkaline water; i. e., it contains free carbonic acid gas, the principal solid ingredient is calcium carbonate, and it belongs to Group B (thermal waters). GERMAN CLASSIFICATION 305 COMPARISON OF CLASSIFICATION SCHEMES Owing to the fact that so many different schemes of classification have been proposed there has been more or less confusion in their application. In order that consideration of the subject may be somewhat simplified, an attempt is made here to corre...
