When one reflects on the many reasons why young women are not, as a general rule, likely to give that close and lasting attention to any branch of scholarly or mechanical art qualifying them to excel, the vehement objections sometimes made to female professionals seem not a little ridiculous. We should like to see the subject treated in a more practical and sympathising spirit. A little consideration might shew that only in a few remarkable instances--such as that of Mrs Somerville--do women possess that resolute spirit of study which leads to eminence in scientific or other learned pursuits. The thing is not to be done off-hand, or by fits and starts, and half-formed resolutions. Look at the hard and tedious work that young men must undergo before attaining proficiency in the practice of medicine. Success with them is a matter of life and death. No one can reasonably expect that any large number of young ladies are ever likely to make similarly enduring efforts. To us there is something melancholy in the exigent circumstances that often in this old country drive ladies to look for subsistence in pursuits not very accordant with the delicacy of their sex. The redundancy of unmarried young women should set people thinking on the causes for so much enforced celibacy. That is a broad department of inquiry somewhat strangely neglected. Neither emigration nor drafting for the army will account for the phenomenon. We have space here only to hint at one or two prevalent errors--or call them failings--in which society is intimately concerned as regards the number of female celibates. Let us first point to the extravagant modes of living--extravagance in dress, extravagance in house-furnishing, extravagance in nearly everything--that has conspicuously gained ground among the middle classes within the past forty years, and in the face of which marriage has become a much more serious affair for men to encounter than it ought to be. There, plainly enough, lies the basis of innumerable mischiefs. For such a state of things, both sexes must bear the blame. Fathers of families are seen mis-expending means, and leaving daughters unprovided for, but with tastes and habits which are incompatible with their position, the result being that they are reluctantly obliged to swell the already overswollen ranks of governesses. On the other hand, the lofty expectations erroneously entertained by many young women, drive away suitors who have still to make their way in the world. Hence, from various preventable causes, the vast numbers of young unmarried women crowding public places of resort.
