Carbon black. Regards, Bob... -------------------- "Let us contemplate our forefathers, and posterity, and resolve to maintain the rights bequeathed to us from the former, for the sake of the latter. The necessity of the times, more than ever, calls for our utmost circumspection, deliberation, fortitude, and perseverance. Let us remember that 'if we suffer tamely a lawless attack upon our liberty, we encourage it, and involve others in our doom.' It is a very serious consideration that millions yet unborn may be the miserable sharers of the event." - Samuel Adams, 1771 From: "Juan J. Buhler" <[EMAIL PROTECTED]>
