either goes out or splutters the grease all over the 

 glass at a critical moment, and oil lamps smell and 

 are dirty. The best all-round lamp is a canary- 

 coloured hock bottle over a good wax carriage 

 candle. Only good wax candles should be used ; 

 the cheap " Stearine " kind bend over from the 

 heat and crack the glass cover. 



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 

 indisputable, and as the hypo can be kept perma- 

 nently in this trough, it is always ready. Any plate 

 can be lifted out for inspection without wetting the 

 hands. 



A porcelain washing trough with grooves for 

 twelve quarter-plates placed vertically side by side. 



One ditto for lantern plates. 



A print washer. 



A graduated water jug.
