 We beg to inform you that the Board of Directors of the 
 ((Crystal Palace » in Oporto, as well as the Society «Photogra- 
 phia Moderna» and some contributors to the ‘Portuguese art Jour- 
 nal=A Arte PHOTOGRAPHiCA=are organising for the months of 
 September and October of the present year of 1 885 an Inter- 
 national Photographic Exhibition, under the patronage of His 
 Most Gracious Majesty I). Fernando, who will offici- 
 ate as President, in which Professional and Amateur photogra- 
 phers, ^Manufacturers of photographic apparatus and products, 
 as well as Editors of publications of all countries, relating to 
 that important division of art, are respectfully requested to take 
 part. 
 
 The Exhibition, which will take place in the great central 
 hall or Nave of the Crystal Palace in Oporto, will embrace 
 every branch referring to Photography as well as its most re- 
 cent applications to Science, Art and Industry. 
 
 By the enclosed programme will be seen the mode of classi- 
 fication and disposition of the different specialities, as well as 
 the conditions under which the Exhibition will be carried out. 
 
 The art of Niepce and c Daguerre so highly appreciated in 
 Portugal, has met in this country with numerous and enthusias- 
 tic adepts who have* assiduously cultivated their profession 
 and brought it to a degree of. proficiency perhaps overlooked 
 abroad. Under these circumstances we consider it expedient to 
 bring together the elements of an extensive competition in which 
 master pieces and the most recent improvements of other more 
 favoured countries should be exhibited. This would give Portu- 
 gal its place in the artistic world, and add to the many favours 
 
 s 
 
already shown us in other countries where we have competed 
 in foreign exhibitions. Besides this, ground for making our 
 attempt, we might likewise call attention to the advantage 
 which would accrue to all parties, — first in view of a diffusion 
 of knowledge and secondly from the international stimulus which 
 must necessarily arise from a vast exchange of products and 
 the subsequent encouragement to general progress and more 
 enlightened study. 
 
 Please then let us know in conformity with the disposit- 
 ion of our programme whether you wish to enter your name 
 as exhibiter, and favour us with your participation in this Inter-' 
 national event. 
 
 Indications as to how much space you would require, as 
 well as what description of photographs you intend to exhib- 
 it would greatly oblige. 
 
 yours most respectfully 
 
 The Principal Commission,
