HMM! I lost a couple of opening paragraphs when I pasted in my above post. So here's how it was supposed to start out:

Thanks a million for your comments, Edwin

After posting my question above, a simple expedient struck me. I went to the Seattle Public Library's web site (my wife works at SPL) and checked their on-line catalog. I found they have two books by Cornelius Reid:   Bel Canto; Principles and Practices and A Dictionary of Vocal Terminology : An Analysis. I put them on hold and Barbara will pick them up when she goes in to work tomorrow.

Then it goes on to "I'm looking forward to. . . ."
