 a dark tint, or stained, the slide should be placed on a 

 piece of white paper. 



Fine needles, e.g. No. 12 ; should be used. 



The teasing is best done under a dissecting micro- 

 scope, and the parts which are not required should be 

 thrown away. 



In teasing bundles of fibres, the fibres are best 

 separated completely from one another and then 

 arranged close together parallel to one another, in a 

 row. 



Teased tissues mounted in water or in aqueous 

 solutions can be temporarily preserved by surrounding 

 the edges of the cover-slip with olive oil.
