 suitable article, the blunt end of a pencil for 

 instance, or better, the small rubber eraser 

 attached to pencils, which may be procured 

 for a few cents. If carefully done, this 

 method of mechanical reduction will be found 

 exceedingly useful and satisfactory in cases 

 where no other could be used. 



Potassium Bromide. Although the brom- 

 ides of potassium or ammonium are so gen- 

 erally recommended and used as restrainers, 

 my own experience has not been favorable to 

 them. Slow development, with rather weak, 

 or even dilute solutions, has always given 

 better results in every way details, density, 

 evenness. With Eiko-Hydro developer, the 

 addition of about one-fourth volume of an 

 old and used solution to the fresh mixture 

 is very satisfactory. Ample exposures and 

 somewhat weak solutions give slow develop- 

 ment, rarely failing to produce better results 

 than short exposures and energetic developers. 



Frilling and Fixation. In the earlier days 

 of gelatine dry plates, frilling was by no 

 means an uncommon occurrence, the entire 

 film quite frequently leaving the plate during 

 the washing after development, and at times 

 becoming completely disintegrated. Although
