The homoeopathic Materia Medica, as it is accessible at present to students, is a mass of symptomatology, arranged, as a rule, according to the Hahnemannian Schema. The "Cyclopaedia of Drug Pathogenesy" is the exception, which endeavors to give the symptoms in the order of their development; but, in order to practically utilize the provings, the anatomical arrangement of the symptomatology is desirable. Besides this arrangement, the bulk of the symptomatology can be analyzed and interpreted helpfully, and thus simplified. All provings of drugs give a symptomatology composed.

(1) Of general symptoms.

(2) Of peculiar or characteristic symptoms.

(3) Of certain elective affinities to special organs or functions.
