Abstract
1. The LD50, slope and error of dose-response curves for the all-or-none type of data may be rapidly calculated with the aid of a series of scales and nomographs.
2. The potency and its associated error for assays involving data of the all-or-none type may also be calculated with these scales.
3. The construction of the scales and nomographs is described and their use is illustrated by an example.3
