Helen Worth's memoirs are a great read and, as others have said, really interesting in terms of a a historical perspective but they have been called into question by others that were there. For example, the story where the midwives have to go onto the ship to deliver the baby belonging to the captain's daughter. Her vagina was so large the midwife was easily able to get a hand in to examine - with the implication that had happened as she had had sex with loads of different men. We know that's utter rubbish these days and couldn't have been the case. It's just as daft as saying the man's penis wears away if he has loads of sex. I expect lots of these memoirs are embellished, which is no bad thing, it's just turning into a complete story. Same with All Creatures Great and Small.
