Mr. W.E.C. - #2,9/25/12.that Only the Lime Starved Get consumption". This is written by physician Caption Phillips and tells at length about how a Dr. Van Gieaen of Germany proved the truth of the title of the article by experiments on lime starved and line supplied dogs artificially infected with tuberouloua bacilli. (NOTE!- The exclusive use by the Chinese of Boiled water In their only beverage-tea - for centuries does not sees to have led to their extermination by consumption. This is, perhaps, because they get their lime salts in their food, as for example, from the outer covering of the aground rice which forms the bulk of the carbohydrate component of their food.)It is not necessary to tell you that the Tuolumne River runs through a granitic soil. The only "fly In the ointment" it the geological fact that of the eight kinds of feld spar, three are found in granite according to Dana, and one of then, oligoclasecaries calcium salts. What kind of feldspar is present in the granite of the Tuolumne Canyon, I do not know. If it is not oligoclase, there is sons basis for this argument of mine though probably it will be combatted by the statement that the calcium salts will be furnished by the admixture of the lime saturated water of the spring Valley Water company supply. Probably one of the members of the Sierra Club who is a geologist can tell you off hand whether the feldspar in the Tuolumne Canyon granite is orthoclase or oligoclase or albite or microcline or at any rate, whether it is 6ti the kind that would impart lime salts to water flowing over it.As I am neither a physician nor a geologist, I am possibly lost in the scientific wilderness of those callings.06324
