To recommend the ‘"Crystal Periscopic Spectacles,"’ and the skill with which Franklin & Co., 148 Main street, our scientific and practical Opticians, adapt them to every sight and each particular case, would be only to repeat what most of our citizens already well know. We confine ourselves therefore to calling attention to their really fine assortment of Military Spy-Glasses and Marine Glasses, which we recommend to the consideration of military men.--Richmond Enquirer.
