must be something wrong about this exorbitant cost which so effectually hinders the very work which photography, in our age, seems so especially called upon to perform, of counteracting the inevitable tendency of old books to scarcity and consequent dearness. Of the numerous official services which photography could render in a library, such as saving time in copying documents, or restoring damaged leaves of catalogues, I say nothing, for fear of occupying your time unduly; and of the innumerable uses to which it can be turned by an ingenious bibliographer I am also silent for the same reason, and because I regard this branch of the case as the especial property of Mr. Henry Stevens, who has proved it experimentally, and who has, I hope, more to tell us respecting it.
