Oh yes - I remember when that book was first published. It's very funny.

Here's a quote from my etiquette book bought at a library cull several years ago, a 1982 reprint of a book first published in 1886:

"Prudery.
Avoid an affectation of excessive modesty. Do not use the word "limb" for "leg". If legs are really improper, then let us, on no account, mention them, but having found it necessary to mention them, let us by all means give them their appropriate name."

I think, from spelling and terms used, that this book was first published in the U.S.A. Title is "Australian etiquette, or the rules and usages of the best society in the Australasian Colonies, together with their sports, pastimes, games and amusements. Revised, illustrated and compiled expressly as a household treasure for Australian homes."
