Mr. Anthony observed that he had also used air-slaked lime, 

 which combining with a portion of the snlphur formed sulphate of 

 lime, a compound which is insoluble in water, rendering the bath, in 

 its working quality, very similar to the one before described. 



The chairman suggested the use of chloride of baryta. 



On motion of Professor Tillman, a committee consisting of Messrs. 

 Newton, Joy and Anthony, was appointed to make further experi- 

 ments with Mr. Anthony's fixing solutions. 



Mr. William Kurtz exhibited a series of very fine silver prints, 

 illustrative of various methods which he had adopted in lighting 

 sitters at his studio ; also very fine effects which he had produced by 

 unusual manipulation in the printing process. He also exhibited 

 several prints very beautifully finished in ink on albumen paper, and 

 others from retouched and plain negatives, which, with the interest- 

 ing description of his method of working, attracted marked attention. 



Professor Joy suggested the propriety of some action on the part of 

 the section in relation to the recent death, during the vacation, of 

 Professor Schonbein, the discoverer of gun cotton. To him all pho- 

 tographers were deeply indebted for the great progress which had 

 been mide in the art within the last few yeai-s. His devotion to sci- 

 ence and his genial nature endearing him to all, and the intimate 

 relation which his discovery had to the photographic world, made it 

 especially appropriate that his family should be remembered and 

 apprised of the deep sympathy which the photographical section of 

 the American Institute feel for the great loss which they have 

 sustained. 



On motion of Professor Tillman, the section unanimously voted, 

 that the chairman be and hereby is requested to prepare and transmit 

 to the family of Prof. Schonbein, a letter of condolence, expressive 

 of the sense of the section in the loss of one so eminent, and whose 

 labors were so intimately connected with those of the photographic 

 profession. 



Professor S. D. Tillman spoke of the success which had attended 

 the efforts of European scientists to procure photographs of the late 

 solar eclipse. It was unusual to find such interest manifested over a 

 single astronomical event. English, French and German expeditions 

 had been fitted out with all the necessary apparatus, and, after travel- 

 ing thousands of miles, were stationed at different points along the 

 line of total eclipse. The German observers were at Aden in Arabia, 

 and the French and English much further eastward. Quo of the
