11. Prof. Daviv Exuis.— Investigation into the Responsibility of the 
Tron-bacteria as Causative Agents in the Formation of Incrustations 
in Watler- pipes. 
Paper gives the results of an investigation which was conducted on behalf of a 
foreign municipality. Incrustations of ferric oxide often form on the inner surface 
of iron water-pipes, even after the inner surface of the pipes has been thoroughly 
smeared with a protective coating. In spite of every appearance of bacterial 
responsibility, the incrustations were found to be due to causes other than the activities 
of the iron-hbacteria. The arguments given in support are probably applicable to 
most cases of incrustations in water-conduits. 
The réle of the iron-bacteria in promoting the formation of iron-incrustations is 
discussed, and the state of their dependence on the organic content in the water. An 
instance is cited in which oxidation to form the higher oxides of iron is greatly 
influenced by bacterial action, considerable discoloration being formed and the water 
rendered repulsive.
