 can be adjusted so that it shall be possible both to see the picture 

 on the screen and also to write or draw at desks. 



The Botanical Photographs Committee of the British 

 Association have prepared a catalogue of photographs and of 

 lantern slides, both amateur and professional. The catalogue may 

 be obtained from Prof. F. E. Weiss, The University, Manchester,

 direct to the photographers.
