Because the uterus receives its nerves from the sympathetic system, which governs nutrition, circulation, respiration with distribution of animal heat, gestation, etc., these functions being out of sight, it is difficult to get at the root of the matter as regards the uterus in a suffering woman. Her sensations and fancies offer, according to her education, organization, etc., a wide field in which to make her a burden to herself and others. Her mind is generally out of order, she knows not why. In the more advanced stages of disease, the functions of the higher nervous system, the organs of sense, and even the mental activities are disordered.

It is these whose existence I ascertain by a thorough examination, and according to these that I regulate my treatment; they give me in every case a more certain starting point than a lengthy account of true and imaginary suffering. If I find, however, no palpable abnormality in the tissue to remove, and prescribe _Aur. mur. nat._ simply as an excellent nervine, following Niemeyer, it occasionally does good, but generally leaves me in the lurch.

The following outline of the drug is by Dr. E. H. Russell, in _North American Journal of Homoeopathy_):
