Now that's getting somewhere! Malcolm, I'm sorry about the breach of Mudcat etiquette. I didn't think my initial thread was going anywhere but downhill fast. I stand corrected, and in the future will hang in there. Somehow I managed to miss the Child reference. I gave my 5 volume set to a band member as an extended loan about seven years ago. The loan appears to be extended indefinitely. Sometimes a "puzzle" like this is rather like a jigsaw or crossword puzzle. You can stare at it forever and not see what it is you are looking for. Then along comes someone who takes one gander and sees the missing piece, letter, word, whatever. Thank you one and all for your help.
