MICROSCOPIC MOTION PHOTOGRAPHY 



AFTER being well started and getting successful 

 lapse-time pictures of growing life the equipment for 

 microscopic work may be assembled. Some wonder- 

 ful pictures have been made by putting the camera 

 on a soap box, level with the lens of the microscope 

 and turning it by hand. But I would say it is impos- 

 sible to depend on good results if you use that

 camera, lapse-time motor gear, light, etc., should 

 slide back and forth accurately and be so arranged 

 that they may be raised and lowered with extension 

 legs, and the more accurate adjustments with a 

 micrometer device. That equipment bolted on a 

 solid table, or better still, a plank fastened on con-
