MULTIPLYING REFLECTOR. 



This apparatus, the invention of D. W. S. Rawson, of Peru, 

 Illinois, enables a photographer to make from four to one hundred 

 jDictures at one exposure. The camera is not turned upon the 

 sitter but upon a series of small mirrors, which throw the image 

 of the sitter into the instrument. The mirrors are placed in a box 

 about three inches deep, having a cover which may be closed when 

 they are not in use. This box and the camera are placed on a 

 board painted black. The camera receives light from the subject 

 via the reflectors, at the smallest possible angle. The box contains 

 fourteen reflectors, which is the number required for common work. 



The advantages claimed over any multiplying camera, are: 



1. The superiority of the work, as nearly every photographic 

 gallery of the present day has at least one good camera tube, no 

 trouble will be found in producing gems or small photographs of 

 remarkable sharpness. 



2. As only one exposure is required, the light is equal on every 

 picture. 



3. No extra camera-boxes, plate-holders, cut-ofis, or apparatus of 

 uny kind to be bought or kept out of the way. 



4. The expense is so trifling that the extra work of one week will 

 pay for it in an}^ gallery. 



Mr. Carey Lea, of Philadelphia, had suggested in the Philadel- 

 jpMa PhotograpJm' for June, an improvement to this apparatus, 

 which consists in arrano^ing the mirrors to a surface having an 

 ellipsoidal form so that the distance from the sitter to each little 

 mirror added to the distance from the .mirror to the lens should in 

 each case be equal. The inventor has adopted the form proposed 

 by Mr. Lea. 



BORNEO— ITS CLIMATE AND RESOURCES. 



The Chairman next introduced to the audience Mr. J. W. Torrey, 

 President of the American colony in the island of Borneo, who 

 spoke for some time on the resources and condition of that country. 

 The following is a meagre sketch of his remarks: 



The President of the colony is Governor, and holds supreme 

 power even to life and death. It has leased 16,000 square miles from
