Biological training of the order we have been considering is, we believe, desirable for all women in the interests, first, of the home and of the rearing of children. But it is equally desirable for the women who are not destined to be wives and mothers, and particularly so as a foundation for any kind of university work, even for the different literary or philosophical schools. Here it is, perhaps, worth while to urge upon women the claims of the other great division of Biology, that of the laboratory. A considerable number of women who go up to the universities have, indeed, intellectual abilities deserving special cultivation, yet abilities which show no very distinct inclination in any one direction. These have been very commonly drafted into the study of history. It may be questioned whether some branch of Biology would not be better for them, and more useful to the community. Women working at Biology in the universities ought to serve, and to aim at serving, as the channels by which each fresh addition of scientific knowledge finds its way to, and its appropriate place in, the schemes of Common-sense Biology generally obtaining. In another field--the field of public work--it is to be hoped that ere long a knowledge of biology will come to be considered a _sine quâ non_ for women. It would be superfluous to point out in how many kinds of public work women are gradually coming to the fore--in those especially which deal with education and with the care of the disabled. Already the influence and the peculiar gifts of women have in some degree made themselves felt; but these might operate much more powerfully if they were more commonly associated with scientific knowledge--with a knowledge of those branches of biology, more especially of bio-chemistry and bio-physics, which bear most nearly upon humanity. It would take up too much space to give an account of the many ways in which biology is here of service: two great lines of utility may just be indicated as examples.
