It is manifest that one may not evolve a scheme by which the course of all symptoms may be charted as one charts temperature, pulse and respiration, but it is possible, with the aid of signs and symbols, to record the variations in the disease and the changes in treatment on single lines devoted to each important detail. No signs may be found better than those used in algebra variously modified and adapted to the purpose, inasmuch as they not only express the meaning with definiteness and elasticity but also are comprehensible universally. The key, therefore, of these charts, may be re- garded as self-evident or might be printed across the top of each sheet in one or two lines: Positive ± Distinctly weak > Strongly positive-]—(- Very weak-)->> Very strongly positive Unchanged = Extreme -f--]—|--j- Absent 0 Doubtful ?
