mel used. It is frequently very dark in color owing to the largo 

 quantity of wax always present in inferior honey. 



After the plate has been washed for a little in distilled water 

 after being excited in the bath, it. is to be plunged into a flat dish 

 containing enough of the Oxymel bath to cover it. This bath is 

 prepared as follows, and may be used repeatedly.

The plate is left in this bath for a minute and is then well drain- 

 ed before being placed in the Camera frame. The plates will keep 

 perfectly well for a week in this climate even during hot weather. 



The exposure is long, viz. with a Ross' 4 inch landscape lens 

 and ^ in diaphram as much as 9 or 10 minutes will be needed to 

 bring out dense foliage. But this process has one advantage over 

 others on Collodion, viz. that provided a sufficient length of ex- 

 posure has been given, no ill effects follow from over exposure, as 

 the picture seems to correct itself in the development, fogging being 

 prevented by care being taken not to carry the first development 

 too far. 



The picture is then washed and dried in the usual way, and 

 finally varnished.
