worth while to offer the parts already printed as a bonus, at a nominal or greatly reduced price. Unfortunately, however, the number of copies printed during the first year was comparatively limited, and the impression, as regards these, would be exhausted almost immediately. The difficulty would disappear if the Museum possessed that indispensable auxiliary to its progress, a photographic department, in which the photographer's salary and the cost of chemicals should be paid by the State; thus allowing photographic work to be done gratuitously for the institution, and at a merely nominal rate for the public. In this case the deficient volumes would be supplied without any expense whatever, and the offer of the perfected sets to the public at a nominal cost would probably ensure sufficient subscribers for the remainder of the work. Until this great step towards the popular dissemination of the Museum's treasures in all departments has been taken, it will be necessary to reprint the earlier volumes of the catalogue; and the £1500 required for this purpose might probably be obtained from subscribers on condition of the other back volumes being thrown in as a bonus at a greatly reduced price. The longer the operation is delayed the more costly will it be for the Museum, which runs the risk of eventually finding itself with a hundred sets, mostly imperfect, on its hands, of which it will be impossible to get rid otherwise than by donation. A subscription once commenced is not likely to drop, as the value of a set of the catalogue depends upon its completeness.
