SCIENCE— ADVERTISEMENTS 



Depending on Good Judgment 



In the present day of competition, not ex- 

 cluding the field of microscope-manufacture, 

 advertising is resorted to in which certain 

 goods are described in flowing literature, 

 as the " best made." In fact, it seems to 

 be in order that every producer, no matter 

 in what line, make this very broad asser- 

 tion, so that the only guidance the con- 

 sumer can find is through actual compari- 

 son of the products. 



We, in our efforts to interest yon in 

 " Leitz Products," will continue to assert 

 that we have " only the best." When it 

 comes to actual comparison of a Leitz 

 Slicroscope with those which are offered in 

 !ompetition, we are satisfied to rest the de- 

 jision entirely on your good judgment. 



When again contemplating the purchase 

 )f microscopes for student use, do not fail 

 to consider our "Laboratory riodel II O." 

 Do not accept as final either our claims 

 or others' claims, but simply send to us 

 for a sample microscope and quotation. 

 Expressage will be prepaid. Needless to 

 say, our special duty free prices on mi- 

 croscopes of the "Leitz Standard" of 

 quality will create thinking. 



Only good, solid reasons will explain why 

 Government Departments and Leading Edu- 

 cational Institutions select Leitz Micro- 

 scopes as standard for Research and Labo- 

 ratory work. 



The proof is in facts--not woi ds. Consider the advantages to be derived from an imported instru- 

 ment. Be convinced — as have many others— and from then on Leitz is certain to be your by-word 

 for microscopes.
