 in a great measure muriates. 



"7. It is, I conceive, right to add, that in all cases, even though 

 the composition of the water seems to bring it within the conditions 

 of safety now stated, an attentive examination should be made of 

 the water after it has been running for a few days through the pipes. 

 For it is not improbable that other circumstances, besides those 

 hitherto ascertained, may regulate the preventive influence of the 

 neutral salts. 



" 8. When the water is judged of a kind which is likely to attack 

 lead pipes, or when it actually flows through them impregnated with 

 lead, a remedy may be found either in leaving the pipes full of the 

 water and at rest for three or four months, or by substituting for 

 the water a weak solution of phosphate of soda in the proportion of 

 about a 25,000th part."
