Physical Apparatus for Projection. 



Physical Apparatus for Projection. 



This collection replaces and cancels that given in Vol. I, pp. 190 192. 



The following pages contain a list of those pieces of physical apparatus which are used in 

 conjunction with -the projection lantern. 



Further details as to these illustrations, references to literature on the subject etc. are to 

 be found in this sams catalogue under the respective list numbers. 



We hold a large selection of photographs, diapositives, microscopical preparations etc. When 

 requiring such, we should be glad if application be made for our complete list of these, stating in 

 connection with which branch of the sciences the photographs and preparations are chiefly desired. 



Projection lanterns, accessories and auxiliary apparatus for projection purposes (for projecting 

 horizontal objects etc.) see vol. I of this list which will be sent on request.
