GUARANTEE of the GOODNESS of PHOTOGRAPHIC LENSES. It frequently happens that Amateurs do not succeed in immediately producing Photographic Pictures equal to those obtained by Experienced Artists. In such cases the fault is sometimes hastily and erroneously charged to the Lenses. To pre- vent complaints on this head, Messrs. Griffin and Co. have arranged witli a competent Photographer to try every set of Lenses which they Import ; and a Collodion Pictures produced by each set of Lenses, will be sold with it, to show the purchaser what the Lenses can effect. The cost of the experiments, and of the Collodion Picture given as a guarantee, will add 10s. 6d. to the prices of the Lenses quoted in the Circular,—for whicli cost the purchaser is ensured against the receipt of Lenses not properly adjusted. 1.
