In Table V. is shown the results obtained by the com parison of the one with the other, that , is to say, each of the black figures in Table IV. has been divided by the corresponding red figure placed beneath it, and the result expressed in decimals, which display the relative liability to skin-disease of each of the stated periods of life. In the diagram annexed (overleaf) is presented a pic- torial view of the results obtained in Table V. The black zig-zag represents the results arrived at in the cases of males, and the red zig-zag the results in the cases of females. Further investigation is necessary to establish what may be the precise interpretation of these fluctuations. But it is clear at a glance that, in the female, skin-disease becomes suddenly and markedly more common at the two climacteric periods of life. * These statistics have been procured by adding each of the items of Table 1. to the corresponding item of Table II., and halving the pro- duct, so as to procure a more average result than could be derived from
