Is the same as that in the “Analytical Therapeutics,” and in the “Condensed Materia Medica.” A more complete and concise review of the arrangement will precede the repertory, which is to follow close upon the last volume of this work.

To facilitate the study of the relative value of symptoms, four marks of distinction have been adopted, ❘, ❘❘, ❚, ❚❚, which correspond to the four degrees in Bönninghausen’s repertory.

❘ Is the lowest, and designates an occasionally confirmed symptom. It is omitted in most cases, but is sometimes used to mark a difference of value in the same line.
❘❘ More frequently confirmed.
❚ Symptoms verified by cures.
❚❚ Repeatedly verified.
☞ Indicates an approved characteristic, but is seldom used, by reason of our not wishing to appear authoritative. It is to be hoped that the combined experience of many practitioners, solicited from all sides, will enable us in a future edition to designate many more symptoms with this mark.
θ The Greek letter “theta” stands between the cured symptom and the pathological condition, or the physiological general state, f. i., pregnancy or climateric years. This by no means excludes the characteristic nature of the symptom in other forms of disease.
⋮ Such observations from the Old School or the New, as are worthy of our consideration.
t. Toxicological.
r. Right. l. Left.
< Increase, or aggravation.
> Decrease, or amelioration.
Π The Greek “Pi” stands before symptoms observed only on the sick.
