A Hint to Publishers

*A Hint to Publishers* (Vol. ii., p. 439.) reminds me of a particular grievance in Alison's *History of Europe*. I have the first edition, but delay binding it, there being no index. Two other editions have since been published, possessing each an index. Surely the patrons and possessors of the first have a claim upon the Messrs. Blackwood, independent of the probability of its repaying them as a business transaction.
