PKEFACE TO FIRST EDITION. 



This handbook is not intended to be an exhaustive treatise 

 on the microscope, nor to give particulars of the various 

 patterns of instruments that are made, of which details 

 can be seen in the makers' catalogues, but to afford such 

 information and advice as will assist the novice in choosing 

 his microscope and accessories, and direct him in his initial 

 acquaintance with the way to use it. 



The directions for preparing microscopic objects by Mr. 

 Martin J. Cole are the outcome of a very long experience 

 as a preparer of Microscopic Objects of the highest class, 

 and cannot fail to be of the greatest service to the working 

 microscopist. 



M. I. CEOSS.
