HAD I INTENDED TO DEDICATE THIS VOLUME, I SHOULD HAVE INSCRIBED IT TO A NOBLEMAN WHOSE EXERTIONS IN PROMOTING EVERY OBJECT THAT CAN ADVANCE SCIENCE REFLECT LUSTRE UPON HIS RANK. BUT THE KINDNESS OF HIS NATURE MIGHT HAVE BEEN PAINED AT HAVING HIS NAME CONNECTED WITH STRICTURES, PERHAPS TOO SEVERELY JUST. I SHALL, THEREFORE, ABSTAIN FROM MENTIONING THE NAME OF ONE WHO WILL FEEL THAT HE HAS COMMANDED MY ESTEEM AND RESPECT.

C. BABBAGE.
