780 OCCUPATIONAL TUMORS AND ALLIED DISEASES although numerous exceptions occurred, there was on the average a slight direct association, as occupations in which there was a relatively high skin cancer and lip cancer rate tended to show, also, an excess of cancer of other sites. Observations made by Southamj Sladden; Roeschj and Bonser and Connal confirm this observation in the occupational cancer field. The claims of Murray and Cramer were not confirmed by Bonser and Connal. The numerous experiments made with tar and various synthetic carcinogens applied to the skin or injected subcutaneously have demonstrated, beyond any doubt, that the presence of a cutaneous malignancy does not pre vent the development of a similar reaction in some internal organ (Bogen and Loomis j Schabad; Lynch j and Andervont). The statistical interrelations observed by Peller represent misinterpretations 6f unrelated data, as this investigator neglects entirely to consider any differ ences which may be present in the type and intensity of exposure to various carcinogenic exogenous agents probably present in the groups subjected to a statistical analysis.
