Proceedings. [No. 9, new series. 



By the kind permission of Mr. Garrett, Dr Scott exhibited the 

 new Stereoscope patented by Mr. George Colleton Cooke and ma- 

 nufactured by Messrs. Nagretti and Zambra of Cornhill. This is 

 the most perfect instrument of the kind which has been as yet pro- 

 duced, and possesses the following advantages. The eye pieces 

 are fitted into trumpet-mouthed tubes by which arrangement the 

 eyes are protected, the field of view is increased, and larger lenses 

 than usual can be employed — therefore less impediment than here- 

 tofore is offered to the rays emanating from the picture, and the 

 eye of the observer is enabled to range more fully over the field of 

 view. In this new form of Stereoscope we have also the adapta- 

 tion to the eye piece of additional moveable lenses adapted to dif- 

 ferent kinds of sight. These lenses are either meniscus, concave, 

 piano, convex or double convex as may be required, and they are 

 adapted to the instrument in such a manner that they are moved 

 into and out of use by small levers projecting through the sides of 

 the box. The only objection to this Stereoscope is that it is expen- 

 sive, the English price being £6-6. It is fixed on a very substan- 

 tial stand which renders it steady, and by an arrangement of brass 

 cylinders contained one within the other it can be elevated or de- 

 pressed between 2 and 3 feet, so as to suit the convenience of those 

 using it either when sitting or standing. 



Those interested in Stereographic art who can afford it, ought 

 certainly to provide themselves with this instrument as the most 

 complete and perfect of the kind now obtainable.
