The optical details enumerated in Specifications 5 and 6 were adopted for the microscopes used in 

 the Prussian Military Hospitals. Professor R. KOCH declares them to be indispensable in 

 bacteriological research. 



The total cost of Specification 6 may be still further reduced by omitting the micrometer 

 eye - piece and by substituting objective D for DD , which would result in a saving of 

 Mk. 30. .
