Teaching Botany 
becomes a pleasure when you use a College Bench Lantern, and our new Laboratory-Lecture 
plan. 
Regular microscope slides are used in the laboratory under a stand microscope, and lantern 
slides are used in the lecture room. The lantern slides are identical with the microscope slides.

You can use actual specimens in the Laboratory and we'll make slides from your drawings 
for the lectures. 
While the College Bench is the ideal lantern because of its absolute alignment and accuracy — 
and the possibility of microscope as < well as lantern slide projection, we have lantern slide 
projectors as low as $20.00, including rheostat. Others from $25.00 up—including opaque 
projectors. 
Our experience is at your service to assist you in getting just the right outfit.
