Entertaining and enlightening. I have added it because I recently finished Dary's Frontier Medicine, and I first learned about women doctors in the Civil War here. I reread this today in hopes of finding an eleusive citation to an American Civil War Era doctor I recall as being the inventor of the return address. This became more necessary during the Civil war because troops moved so much, especially the hospitalized. Dr. Mary E. Walker is the only female Civil War doctor mentioned here and the citation I was looking for must have been elsewhere. And apparently the invention is actually far older, but this is, if I am recalling my mystery resource correctly when it became commonplace. In rereading this I realize that there are no sources stated here and I am encountering a number of things that seem factually questionable, such as how long Dr. Walker stayed married to her husband. This is an entertaining book and one I have retained for something that is apparently not present. Onward and outward.
