BEOWNING'S 

 NEW LANTERN MICROSCOPE. 



This apparatus has been devised to meet the wants of Lecturers on Natural History, Physiology, an 

 kindred subjects, who have hitherto been unable to display ordinary Microscopic Slides with the 

 O.xyhydrogen or Electric Light ^Lantern on a Screen. 



All ordinary Microscopic Slides of suitable subjects may be shown with the New Lantern Microscope, 

 but Messrs. COLE and SON, the celebrated mounters of Microscopic Objects, have kindly undertaken 

 to make a series of Physiological Preparations adapted for use with the Lantern Microscope specially for 

 Mr. BROWNING.
