Definition 1.1. A differentiable manifold is a set M together with a collection of subsets Oα such that 1. ∪αOα = M , i.e., the subsets Oα cover M . 2. For each α there is a one-to-one and onto map φα : Oα → Uα where Uα is an open subset of R. φα are called charts and the set {φα} is called an atlas. 3. If Oα and Oβ overlap, i.e., Oα ∩ Oβ 6= ∅, then φβ ◦ φ−1 α : φα(Oα ∩ Oβ) ⊂ Uα ⊂ R → φβ(Oα ∩ O...

as part of the moral order on the one hand and as pathological phenomena on the other. Dr. Riese writes interestingly of his seventeenth century theorists, and the reader will find much of what he has to say rewarding, especially with respect to the work of medical men so little known as de la Forge and de la Chambre. Rather than praise the obvious merits of Dr. Riese's monograph, however, I sh...
