which has not yet been explored, or at least has not yet sent its 

 records to the Union's collection. We refer to micro-photographs 

 of geological sections. A number of these are constantly turning 

 up in illustrations of papers, and are often thrown on the screen 

 at lantern lectures, so we think there must be some prints to be 

 obtained, and would ask the members of the Union to help us in 

 collecting a series for the Union's Albums, where they would be 

 handy for reference to students who are not the possessors of 

 microscopes. 



During the year the albums have been on exhibition at the 

 Crossbills Scientific Society's Annual Conversazione. 



The following photographs have been added during the year :
