It is fitted with Terrestrial or day eye-piece of high magnifying power and 

 brilliant definition, and one Astronomical eye-piece of sufficient power to exhibit 

 all the phenomena of the planets and divide the more easily resolved of the double 

 stars. 



The whole instrument is compactly arranged in a mahogany box with lock and 

 key, forming one of the most useful and convenient Telescopes for Tourists or 

 Sea coast visitors. 



It can be used without the stand, as an ordinary pocket Telescope.

N. & Z., in view of the increasing demand for Astronomical Telescopes of 

 moderate price, have constructed one that, while it accomplishes eifectually all 

 required in an elementary study of the heavenly bodies, is equally useful as a 

 Telescope for Terrestrial objects, or for marking in Rifle practice. 



It will show Jupiter's moons, Saturn's ring and moons, and resolve some of the 

 double stars ; while for terrestrial objects, it will define well at a distance from 

 10 to 15 miles, and will show bullet marks on a target at the longest ranges. 



For Astronomical purposes, an extra eye-piece can be had, magnifying 80 

 diameters, price 12s. 6d. Can be added at any time.
