The following apparatus and chemicals will be 

 sufficient for a quarter-plate outfit : 



Two developing dishes, with a, lifter at one end 

 to raise the plate, so that it can be grasped at the 

 edges and lifted out for examination. This simple 

 rocking lever fixed in the end of the tray enables 

 one to keep one's fingers almost free from contact 

 with the chemicals a great boon, preventing both 

 rough skin and stained fingers. 



Two glass graduated measures. 

 .A vertical fixing trough with six frames for plates. 

 The advantage of the vertical position is indisput- 

 able, and as the hypo can be kept permanently in 

 this trough, it is always ready. Any plate can be 

 lifted out for inspection without wetting the hands. 



A porcelain washing trough with proov 7 es for 

 twelve quarter-plates placed vertically side by side. 



One ditto for lantern plates. 



A print washer. 



A graduated water jug. 



A drying rack. 



Two or three large dishes for water, hypo, and 

 acid baths, used for bromide and platinotype 

 prints ; also one for toning if P.O.P. be used. 



A hand magnifying glass.
