To the Editor:—  In the editorial comment on poliomyelitis virus in sewage (The Journal, September 7) the statement is made that "Kling's theory was presumably based on experimental or statistical errors." Kling's work was done on poliomyelitis organisms occurring in Stockholm sewage. The American investigators used American sewage and a mixture of laboratory strains of the organisms and did not obtain the same results as Kling. Is it fair to conclude therefore that Kling's theory was based on errors, either experimental or statistical, considering the possible differences in the sewage and the strains of the organisms? Would not the penultimate sentence have been a more scientific as well as a more courteous conclusion?
