Dear All,

            I must prepare some blood film slides for the diagnosis of malaria (thick and thin films).  I would like to preserve these slides for a long time.  Coverslips are, in fact, a viable option

1.  what is the best mounting cement to use?  I am concerned with cracking or yellowing of the cement.

2.  will I be able to find cover slips that are nearly as big as the entire slide?
