Yer forgiven. Appeared to be tossin' Richard Law and his fine book 'Backbone' under the bus. Heck, I have a mid-fifty's publication of the 'World Book' from my childhood days stored in several boxes I take out once in a while and browse through-still good info. Have to check updated facts that have since been discovered/updated once in a while. Kind of fun anyway, takes me back to when I use to pour through them from cover to cover as a lad. Guess that's what sparked my interest and knowledge in history and science which were easy subjects for me through school. Have a good day.
