A cell about 5 mm. in diameter must be smoothly punched towards one 
end and a 12 mm. circular or square cover glass be gummed or otherwise 
attached to the underside of the mount and allowed to dry (under cover) 
for several days before using. A stock of these may be prepared ready 
for use when necessary. Instead of entirely dissecting out the genital 
organs from the pygofer, as would be done for making a slide, manipulate 
and prepare the object as would be done for mounting on card point, 
taking care, however, that. the dissection has later been transferred 
to alcohol and then into either Xylol or Clove oil before it is finally 
transferred to the Canada Balsam cell. The transfer from Clove oil 
or Xylol to the cell (in which a drop of Balsam has been placed) and the 
manipulation required to secure a proper lateral view of the margin 
of the pygofer, the armature if any, the anal tube and spines, the 
genital styles and aedeagus, is a delicate process, but fairly easy after 
a little experience. Before placing the final cover glass over the object 
it is well to wait a day or two and be sure that the object has not changed 
the desired position and that further manipulation is not required. 
Should a change be necessary, soften the Canada Balsam by passing 
the mount quickly, for a second or two, over the alcohol flame then 
using Xylol on needle points to alter the position of the objects. Once 
assured that the mount is satisfactory, another drop of Canada Balsam 
to take the final cover glass will end the process and give the student 
a perfect and permanent specimen of the genital organs. The pin of the 
insect mount can be run through the end of card cell and so allow 
the specimen and mount to be placed in the cabinet together. If the 
card cell sags, a small piece of cork can be glued to the underside of 
the card cell where the pin pierces it.
