    Appendix to same. S. L. Dana, M. D. My convictions are decidedly against the use of lead, pure or alloyed, or tin coated, for conduits of water to be employed for domestic purposes. Christison's Treatise on Poisons. Rain or snow water, for culinary use, should not be collected from leaden roofs, nor preserved, nor conveyed in lead ; the same rule applies to spring waters of unusual purity, where, for example, the entire impregnation does not exceed a 15,000th of the water. Spring water which contains a 10,000th or 12,000th of salts may be safely conveyed in lead pipes, if the salts in the water be chiefly carbonates and sulphates. Lead pipes cannot be safely used, even where the water contains a 4,000th of saline matter, if this consist chiefly of muriates. Spring water, even though it contains a large proportion of salts, should not be kept for a long period in contact with lead; and cisterns should not be covered with lids of this metal. Encyclopedia Britannica. Article Lead. Bicarbonate of lime exerts a remarkable preservative influence, and as it is a very common impurity in water, few spring waters exert much action on lead Water highly charged with carbonic acid may dissolve lead to a dangerous extent. Murpratt's Chemistry applied to the Arts: Lead. The first stage of slow poisonings are very frequent, and well known to most of the general medical practitioners in every large
