Reoolomg Rosepieces 
The Revolving Nosepieces herewith listed are recommended for use with 
every microscope where more than one objective is employed. They are con- 
structed after new and improved methods and are extremely accurate and not 
liable to get out of center. When the nosepiece is ordered with the microscope 
the objectives are centered to it gratis. All objectives of one-inch focus, or less, 
will be mounted so that when attached to the nosepiece they will focus in the 
same plane if ordered with a nosepiece, otherwise they will require slight 
adjustment to bring them successively in focus.
