2nd. Because her milk being necessarily of a bad quality, it cannot be expected that the child will derive benefit from it; but, on the contrary, there is every probability that his health will suffer by using diet of such an improper description. The obvious dependence of the foregoing symptoms upon debility will, of course, at once suggest to practitioners the nature of the treatment to be adopted: which should be such as is calculated to invigorate the system generally--namely, the administration of tonics, &c. Bark and its various preparations, especially the sulphate of quinine, with the occasional use of warm aperients (sedulously avoiding the more violent purgatives), will be found eminently successful; whereas, cupping at the nape of the neck (which I have seen prescribed for the headache), and other depletory measures, have proved as manifestly injurious. 'Every disease productive of great weakness is increased by the state of the system which follows child-bearing. Of this description are consumption, dropsy,' &c. In these cases it is evident that the process of lactation, by adding to the debility already present, must prove highly injurious, and consequently should be always avoided. I have already noticed the effects which are produced upon the milk by the influence of mental emotions on the part of the mother, as well as by the recurrence of the periodical appearance; and since these are chiefly injurious to the child, by depraving its sustenance, their further consideration will be deferred till the next chapter. With respect to the remaining topic--namely, the occurrence of miscarriage from suckling--I am convinced that it is by no means an unfrequent accident, though its real cause is perhaps rarely suspected, having only met with one patient who considered the mishap in question to have arisen from keeping her child too long at the breast. Having already, I trust satisfactorily, explained the manner in which abortion is produced by the act of suckling, I shall conclude this part of my subject with the relation of a case that occurred in private practice, which so strongly corroborates many of the observations in the preceding and following pages, that I shall offer no apology for its introduction: more particularly, since the lady herself to whom it refers has benevolently expressed a wish for its publication, in order that those who become acquainted with the facts there detailed may be prevented from undergoing similar unnecessary sufferings:-- CASE.
