R. T. E. MERRITT'S IM- 

 PROVED PATENT CAMERA. 



This has, by several eminent Photographers, 

 been pronounced to be the best yet offered to 

 the public. For all the Paper, Albumenized, 

 and Moist Collodion Processes, it is at once 

 facile, perfect, and portable ; and as many 

 pictures as may be desired may be taken in 

 succession, and dropped into a receiitacle pro- 

 vided, without the possibility of injury from 

 light. And, if requisite, those in Collodion 

 maybe developed, so that the quality of the 

 light may be ascertained.
