The prevalence rates and distribution of dysplasias and cancer of the uterine cervix were studied on 26,110 women in the Agra District of India. Derived incidence rates indicate that Agra is among populations of highest risk for cervical cancer in the world. Early marriage and multiple pregnancies are reiterated as important factors. Hindu women had approximately twice the prevalence of cervical cancer seen among Muslims.

TuNIOURS of oral and oropharyngeal regions are the commonest miialignant tumours in North India. A number of studies (Khanolkar, 1944(Khanolkar, , 1951 Paymaster. 1956;Wahi et al., 1958) have brought out the close relationship of these tumours to environmental factors. The nature and the mode of use of the offending agents which are thought to be responsible for cancer in these regions vary from place to place. Likewise the anatomical location of tumours and their clinicopathological features are apt to be different. The purpose of this paper is to present the salient clinical and pathological features of these tumours as seen in the northern part of India. specially in the state of Uttar Pradesh. MATERIAL AND METHODSDuring the years covered by this study Bross (1958).Ridits are based on the observed distribution of response variable for a specified set of individuals. Ridits present a new application of an old idea (the probabilitv transformation) and are closely related to distribution-free method based on ranks. Ridits indicate the degree of a particular class by number. The average ridit has probability interpretation-it is an estimate of the chance that 27
