This is a picture of Williams Obstetrics, one of the text books my dad used in medical school:Williams Obstetrics is still used in medical schools, but there’s something funny in the index of the 16th edition that you won’t find in the current 23rd edition. Look in the back under “Chauvenism” and you come up with this:
Rumor has it that the wife of the author was involved in the editing and indexing, and she apparently inserted her own opinion about the book. However it came to pass, “Chauvinism, male, voluminous amounts” is listed in the index of the sixteenth edition, with the starting and ending pages of the book as reference. I think it’s a funny commentary on the field of obstetrics at that time.
This article from http://www.theuncesarean.com shows photos from both the 15th edition (index in that issue reads “Chauvinism, male, variable amounts 1-923.”) and 16th edition and has a few more details if you’re interested.
