PATTERSON, Registrar 2421 South Dearborn Street Chicago, Illinois Leitz Microscopes are the LEITZ LABORATORY AND STUDENT A Student Microscope is naturally subjected to hard usage and in order to withstand severe handling, its workmanship has to be durable beyond question. The Leitz Laboratory and Student Microscopes embody the same high standard of optical and mechanical workmanship, so strongly identified with Leitz products, and are guaranteed, therefore, to serve in student laboratories in a more satisfactory manner than any others. The "Leitz-Quality" is beyond comparison, and since it is unequalled, it is supreme. Optical and Mechanical Efficiency are the chief points expected of any microscope; the Leitz instruments are recognized to possess these standards to a non-contestable degree.
