Too much care cannot be taken in selecting the remedy. The symptoms should be closely compared with those delineated under the heads of that class of remedies most likely to be indicated. The cause of the disease has also an important bearing in the selection of the medicine. The mind should be directed to the leading symptoms, the pecularities of the disease, and notwithstanding it is not necessary that all the symptoms noted should be present, yet the utmost care should be taken, that there are no symptoms present not covered by the medicine, or at least more strongly indicating another. The totality of the symptoms or the symptoms taken as a whole, should be the guide.
