RESEARCH 
While several research projects in cooperation with contributors 
are in early phases, the principal study has been on the nature, in¬ 
cidence, and etiology of epidermal carcinomas and papillomas in several 
populations of fish, under the auspices of the Committee on Comparative 
Oncology of the Union Internationale Contre le Cancer (UICC). This Com¬ 
mittee is composed of eight scientists each of which, with a small work 
group, is making an in-depth study of one or two particular populations 
of lower animals with a significant incidence of a neoplastic disease. 
The purposes and objectives of this Committee have been described in 
detail by its Chairman (Dawe, C. J. Comparative Oncology and Environ¬ 
mental Carcinogens. UICC Bull. Cancer, {$(4): 2-3; Dec. 1970).
