    6. Endothelioma.—None in my series. 7. “Cancer the only designation. Cases 28, 35, 39, 40, 41, 42. Total, 6 cases. In only 3 of these 6 cases are the ages and sex given. There were 2 males with an average age of thirty- eight years and 1 female of seventeen years. COMBINED STATISTICS, McWilliams. Rolleston. Totals. Per cent. Average age. Columnar-cell cancers. 11 5 16 22.5 43.5 Spheroidal-cell cancers. 22 16 38 53.5 23.5 Transitional cancers. 1 6 7 9.8 32.7 Mixed cancers. 4 0 4 5.6 29.7 Colloid cancers. 1 2 3 4.2 Endotheliomas. 0 3 3 4.2 Total. 39 32 71 32.3 From these statistics we see that the spheroidal-cell cancers are 30 per cent, more frequent than the columnar-cell types. There is also a difference of twenty years in the average age in¬ cidence in the two varieties of cancer, the average age in the sphe¬ roidal-cell cancers being twenty-three years and in the columnar¬ cell type forty-three years. If we compare the frequency of these various types of cancer in the remaining portions of the alimentary canal, we find the fol¬ lowing to be the case in this regard: Peterson and Colmers: Large intestine: Per cent. Adenocancer. 86.5 Spheroidal cell. 13.5 Kappers and Van Rooyen: Stomach and intestines: Per cent. Adenocancer. 56.6 Mixed forms. 13.2 Spheroidal cell. 20.7 Colloid. 9.5 Intestines alone: Adenocancer 72.7
