If we divide this table into three sections of five, five, and four years, respectively, we have the following: This last table indicates an increase in the number of deaths due to cancer, but as I have not the actual number of people living at the cancer age, the actual increase, if any, cannot be determined now. This increase, if any, seems to be principally in cancer of the stomach and liver, as shown in Table No. 6. The second five years show an increase of 62 deaths over the first five years, and the last four years show within one death of the number for the previous five years. Or the last four years show an increase of 22 deaths over the previous five years, and they, in turn, an increase of 54 deaths over the first five years. Now, this increase may be due to one of three things: First, an actual increase of primary invasions of the stomach or liver. Second, to secondary invasion of these organs after operation on breast or uterus. Third, greater care and knowledge of the physicians, producing more accurate diagnoses. Yet when we examine the list of deaths due to cancer of breast and uterus we find that there is also an apparent increase, in spite of the fact that many cases of cancer of the breast or uterus are successfully and permanently removed. Or, with the average number of deaths added for 1905, we will have an increase of 47 deaths over the second five years. Cancer of the uterus, however, does not show so great an in This shows (when we add the average increase for 1905) 272 deaths—an increase of 14 deaths for the third five years. It is interesting to note the disproportion of the whites and negroes affected by this disease, the negroes apparently being less susceptible. As I do not know the number of negroes living between 20 and 70 years of age, and also the average age of the negro at death, I can only draw attention to the fact that while there are 86,000 negroes and 464,000 white people in Baltimore, or a little more than one-sixth of the entire population, yet they show about one-ninth of all the deaths due to cancer. While it is an acceptable explanation of this difference in the two races to say that perhaps the negro does not average as high in the cancer age as the white people, yet it is certainly true, as shown in Table No. 2, that average age at death (due to cancer) of the negro is much less than that of the white people-49.454 years as compared with 57.689 years. A careful examination of Table No. 3 will demonstrate, I think, the far less frequent occurrence of cancer in the negro of those portions of the body where we usually have epitheliomata. The distribution of the red dots on the map showing the location of deaths is singularly uniform throughout the entire city. Certain blocks, or, rather, one side of a block of houses, show an unusual number of houses in which death from cancer has occurred, yet so far in the investigation no "cancer houses" have been demonstrated.
