ABSTRACT
The Stereoscope is now seen in every street, it is found in almost every drawing-room; philosophers talk learnedly upon it, ladies are delighted with its magic representations, and children play with it. Notwithstanding this, one can finds a very general ignorance prevailing of the principles upon which this instrument is constructed and still greater want of knowledge of the philosophy which it involves. If the construction of the stereoscope is described first, the subsequent explanation of its principles and its phenomena will be rendered more intelligible. The accompanying figure represents one of these instruments, mounted in the manner now adopted by the London Stereoscopic Company. By carefully examining the views of Meirengen, in Switzerland, and of St. Peter’s, at Rome, which have been engraved with much precision from the immense stock of the London Stereoscopic Company, it will be seen that the pictures are not identical in either case.
