Abstract
THAT a straight-edge laid across three coplanar linear scales will serve to express a multilinear functional relation between the indicated scale readings is obvious ; if the linear scales are not uniform, more complex relationships can be dealt with. But the step from these simple ideas to the construction of the alignment charts used increasingly in engineering, industry, business and other fields is considerable, and demands skill in design and draughtsmanship as well as in orderly computation. Profs. Douglass and Adams are anxious that the young nomographer should not try to run before he can walk, that he should realize "how small a portion of his entire problem the theoretical solution represents ". Thus they begin with a painstaking discussion of scales, occupying six chapters, before starting their discussion of the simpler alignment diagrams in a series of nine short chapters, the last of which deals With the hexagonal diagram for the relation
