The British Sewage Commissioners reported concerning their examination of the irrigation fields at Milan, that they find no evidence whatever of the slightest injurious tendency of irrigation conducted with the waters of the Vettabbia [sewage irrigation], beyond those of other districts around, and where plain water is employed. The sum of all the evidence makes it clear that diseases which are communicated through the discharges of the bowels, such as cholera, typhoid fever, dysentery, and diarrhoea, are not communicated by sewage irriga- tion, even among the families living and working on sewage farms. The most serious evil that has been feared in the past quarter of a century was the communication of entozoic diseases, due to the known vitality of the germs of tapeworm and other entozoa. Dr. Cobbold, the highest authority on this class of infection, expressed, in 1865, great fear that these diseases would be spread by sewage irrigation. Professor Corfield and Dr. Parkes, in their work on the Treatment and Utilization of Sewage,1 after a long discussion of this subject, say: We see no reason, therefore, to alter our opinion that it has not yet been shown that sewage irrigation has ever increased the amount of entozoic disease in men or cattle, still less that it is likely to do so to a greater extent than any other method of utilizing human excrement.
