SIMPLE APPARATUS. 



PHOTO-MICROGRAPHY WITHOUT A MICROSCOPE AP- 

 PARATUS FOR THE WORK THE ILLUMINANT 

 MAKING THE EXPOSURE OBJECTS SUITABLE 

 FOR WORK OF THIS CHARACTER. 



It is desirable that the worker should have the 

 whole of his apparatus within easy reach during 

 the operations of centring, illuminating, and focus- 

 sing the specimen without change of posi- 

 tion ; but in low power photography when no 

 microscope is employed, this is not possible. 

 Still, if he stand to his work instead of sit, it is 

 only necessary to bend the body to the right or to 

 the left in order to command a view of the field at 

 both ends of his apparatus. 



Instead of the microscope, an enlarging camera 

 is used, which comes in useful afterwards for en- 

 larging negatives, but a wood box covered at the 

 open end by a focussing cloth will answer equally 

 well. The handy man will readily see what portions 

 he can make himself, and cut his coat according 

 to his cloth.
