This important work, the result of many years’ careful investigation 
on the part of the Author, will, it is hoped, meet a want long felt by 
Microscopists. It will consist of a volume of text extending to about 
800 pages super-royal 8vo., and an atlas of 48 plates, containing many 
hundred figures. 
Prospectus and Specimen Page may be had .
