________________ ( xviii) keep the lamp burning in spite of storms and stress, we would be keeping their memories alive and our cultural progress undiminished. There is a popular saying : think of the Devil and the Devil is there. But the Printer's Devils are there even if we do not think of them. They simply wipe out our best efforts to make this work free from faults or mistakes. For this we may only crave the indulgence of our kind readers.
