    Mineral Substances.—There is one mineral substance which we require in considerable quantities, viz., common salt, chloride of sodium. The blood is rich in.salt, and a deficiency of salt in that fluid would entail serious consequences. Apparently the quantity of salt demanded daily is about 200 grains. Tlie symptoms of salt-famine are very little knoATO : but it is obvious, that, if salt were rigidly excluded from the dietary, a fatal result would be inevitable after a while. Next to common salt comes potash-salts, deficiency of which is said to cause scurvy. The other mineral substance, necessary to onr nutrition, are required in comparatively small cjuantities, and rigid ex- clusion of all other mineral substance from the dietary would produce no immediate effect, and would only make itself felt after the lapse of a considerable time. In order that the liones may be strong and capable of maintaining their natural shape, there is need of a certain quantity of phosphate of lime. This phosphate of lime must be provided by the food. Early in life during the period of growth—there ought to be a proper supply of phosphate of lime in the food. Such a supply is found in milk, which moreover contains the phosphate of lime in a state of chemi- cal combination with caseine, in a form eminently suitable for assimilation. Flesh-meat likewise contains phosphate of lime. Fish also contains phosphate of lime. The production of bone is a very slow and gi'adual process, and a very small proportion of phosphate of lime introduced into the dietary of a growing child is capable of making the dilicrcnco between deformity and proper developement.
