This course also involves delayed earning capacity, as she must be prepared to face outlay for several years without much return. During this time she generally augments the income which she gets from her private practice by other part-time paid work, notably by giving lectures in first aid, etc., by school inspection, where part-time officers are appointed, and other such work. She also generally does a certain amount of voluntary work on that most pernicious system of giving her services in order to get known. It is in this way that doctors are everywhere so terribly exploited. When they are _all_ so busy doing work which they think will bring them into the public view, this becomes of no particular use to any of them, and the only people who benefit, and at the same time scoff, are the members of the general public, who become so used to getting the doctor to work for nothing or next to nothing, that it comes as a shock when they have to pay. It is a healthy sign that the long-suffering doctor is at last beginning to show symptoms of fight, and in the future it may be hoped that doctors, like lawyers, will not be required to give their services free to the community. It may be true that if a man will not work neither shall he eat, but the converse should also be true, that if a man works he should eat, and at present it is not by any means always true of the doctor. (c) Should she decide to enter the public service, she will still require to take a certain number of posts, especially those dealing with eyes, ears, and skin, and must also obtain the Diploma of Public Health. To gain this diploma she will need to devote several months to post-graduate study in that subject before taking the necessary examination. The chief posts at present open in the public service to a woman are:-- (1) School medical officer, or assistant medical officer of health. (2) Assistant medical officer in some asylums and poor law infirmaries. There is one woman inspector of prisons who is a medical woman, but she is not a medical inspector and was not appointed in that capacity. It is much to be hoped that women prison medical officers will speedily be appointed on equal terms with their medical colleagues. The conditions for women prisoners from the standpoint of health are, at the present time, extremely unsatisfactory. The tendency is to employ more and more women in the public service, and therefore the opportunities are likely rapidly to become more numerous.
