But it is not of those who are merely inconvenienced by illness that we would speak to-day. Not of those who are only subjected to the loss of a little pleasure, a good deal of temper, and who are learning a lesson in being patient. In a word, we do not write for the well-to-do invalid, but for a very different class. Our remarks are intended especially for those of "our girls" to whom health is, perhaps, the only capital they possess. To whom loss of health means loss of work, loss of wage, anxiety, which aggravates matters, and perhaps serious privations to those in any way dependent upon their exertions. Yes, the army of girl and women workers in this great metropolis is, indeed, a vast one, and work for them is no sinecure. If they cannot work so thoroughly or efficiently as men, at least it is for them greater toil than for the sterner sex. Of a more delicate organisation, of less robust frame, of smaller powers of endurance, the "buffets of fortune" meet with less resistance, and are more readily yielded to. Added to this, men have the advantage of being early trained to the habit of work which many of our girls have not, and they have greater facilities afforded them for outdoor exercise, of which they very readily avail themselves. These are all advantages which women do not possess, or if they do, it is after a careful course of acquired systematic training with a view to meet those demands upon their health and strength which are entailed by the continued and steady application to one branch of labour or to one particular profession. There is no doubt that a girl cannot take up an engagement which demands her daily presence at a stated place and at a given time, to perform duties which perhaps require the concentration of mental powers, and very frequently the maintenance of the body in one position for many hours together. There is no doubt, we repeat, that unless such avocations are begun and continued with decidedly common-sense views as to diet, hygiene, and general deportment, but little time will elapse ere our girl will succumb for a greater or less period to the unusual fatigue and the unwonted restrictions to which she has to submit.
