NEGRETTI & ZAMBRA'S 

 IMPROVED YACHiTING AND DEER-STALKING 



811 These Binocular Telescopes are, from the adjustments, 

 suitable to every sight and width of eyes. The Field is large 

 and clear, with an abundance of Light, while the Magnifying 

 Power is great. By the new adjustment, the circles of the 

 two Fields are made to coincide exactly, so that all strain 

 is taken from the eyes in looking through them; while the 

 breadth of the Field enables the observer to " pick up " 

 any object at once. 



Negretti and Zambra recommend their Binocular 

 Telescopes for Yachting, Deer-Stalking, Military Service 

 or general Field use.

812 Negretti and Zambia's new "Binocular" Telescope. By 

 a further improvement in the arrangement and combination of 

 Lenses NEGRETTI & ZAMBRA have now produced a Glass of 

 only eight inches in length, possessing all the advantages of the 

 largest Binocular Telescopes. 



Great Reduction of bulk and weight, combined with High 

 Magnifying Power, and large Field of Yiew are the special 

 points recommending these New Binocular Telescopes.
