WONDERFUL NEW SKY PHOTOGRAPHY.

Remarkable discoveries ooneerr.itis the planets and the heavenly ho.i-es are constantly being made thro:::i aew methods in the sci-mre of p!p i - graphy. It has lone; keen ;-.vowr. •::a: 'he camera can detect o-,ye-s a.:".: movements of the heavi ns which :■.■:■' neyond the reach of the human cyr >ven with the aid of a tcie-a-op,-, A new method of phnto-.-rard-.-.-.

It is to IVofes-; r !.:;■;■- man, of the Paris University, th it we are indebted for the wop ]>'vr.A A'.-:.--jyed plate. which requires : •.tip-r separate lens nor camera. The surface of the plate is covered. vv;rk tiny .enses, of which there are t.-,.n.i!i ;n the square inch, the wh-de- form in:: a vind of gelatine honiqcc- m,h.

The plate has merely to he ex;., s- ! for a certain time, and then it <• -,a '• •- covered and. treated. The res-vt is a wonderful photograph, which is fa.fliffcrent from any now known, as the -ibject.s stand out in relief as th u_-'i seen through a stereoscope. an ; the perspective is not distorted,, whali is the case with the preset;: met!;,,;;.
