Chapter VI, on the Geographical Incidence of Cancer Throughout 

 the World, brings out forcibly the wide range in the cancer 

 frequency rates of different countries and cities with widely 

 varying circumstances of race, climate, habits, etc., all of which 

 are shown to have an important bearing upon the cancer prob- 

 lem as a whole. * * * jj^ chapter VII, on The Statistical 

 Data of Cancer Frequency in American States and Cities, the 

 rate of cancer occurrence throughout the United States is dis- 

 cussed at some length, and amplified by an appendix of 259 tables 

 of cancer mortality for the registration area and for the several 

 states and cities in a uniform manner and with a due regard, 

 as far as practicable, to the elements of age, sex, race, organs 

 and parts, etc. Chapter VIII presents the corresponding infor- 

 mation on The Statistical Data of Cancer Frequency in Foreign 

 Countries, with an appendix of 389 tables for countries other 

 than the United States. Chapter IX concludes the results of the 

 statistical inquiry with Some General Observations and Conclu- 

 sions on the Cancer Problem. This is a general discussion of 

 practically all the more or less controversial aspects of the cancer 

 question, with a first regard, however, to sociological, anthropo- 

 logical and general scientific consideration. * * * -phe ap- 

 pendix to this chapter includes reprints of suggestive educational 

 circulars used in connection with the nation-wide propaganda 

 for cancer control under the auspices of the American Society 

 for the Control of Cancer, etc." 



A bibliography of the important works and articles on cancer 

 is included.
