    The actual gradients are of course different in the two cases, but the relative positions of the counties are not so much affected as might have been surmised; nevertheless, as there are certain alterations, we shall confine our remarks to the age-corrected figures. At first sight it would appear that the gradients justify Dr. Stevenson’s suggestion: we should anticipate that the London gradient would be the least, and so in fact Table Ib.—Corrected Death-rate from Cancer per 1,000,000 living for Three Urban and Two Rural Registration Counties,* 1881-1900.

The two rural counties have the next smallest gradients to London, Somerset not being very different from the metropolis, while the highly urbanized county of Lancashire has the steepest gradient in the series. It is difficult to suppose that Somerset and Lincoln represent a later phase
