Sunday-school Workers find it manageable and 

 specially useful in explaining Bible scenes and localities, 

 and Oriental manners and customs. The Sunday-school 

 Concert is made intensely interesting by illustrating the 

 recitations of the children, and by projecting hymns upon 

 the screen, to be sung in concert. Series of Bible and 

 Holy Land Views are very carefully selected, with special

 for seventy-five dollars.

 and other Societies, for ordinary Public Exhibitions, for 

 Social Entertainments, for conveniently showing up 

 chemical reactions, living insects, minnows, water newts, 

 etc., photographs of microscopic objects, natural and dis- 

 eased tissues, enlargements for sketching, negatives and 

 positives for examination and discussion in photographic
