Abstract

In addition to the 1824 and 1827 books known to have been written by Lady Mary Shepherd, another philosophical treatise, published in 1819, has sometimes been attributed to her. While evidence for this attribution has so far been inconclusive, this paper provides reasons for thinking that Shepherd was not, in fact, the author of this book. New external evidence is provided to show that the author was James Milne, an Edinburgh architect and engineer.
