 cially the instrument by the use of which these 

 discoveries have been achieved the Compound 

 Achromatic Microscope. It is called Compound, 

 from more than one lens being employed ; and 

 Achromatic, or without colour, from being so 

 constructed as by a combination of lenses to 

 bring the light, broken by one lens into various 

 rays of different colours, to be re-collected, or 

 nearly so, by another lens, in such a way that 

 the object to be viewed is seen in a distinct and

 least two compound lenses must be employed ;
