The book "Benjamin Franklin of Old Philadelphia" by Margaret Cousins doesn't have a set number of chapters. It's more of a collection of vignettes and stories about Benjamin Franklin's life in Philadelphia, rather than a strictly structured biography with chapters.
It's likely that the book is divided into sections or parts, focusing on different aspects of Franklin's life and contributions.
