The Photographic Section will furnish a separate Report 

 containing all particulars of their jNIeetings. We are indebted 

 to this Section for assistance in illustrating a large proportion 

 o the Papers read before the Society. Scientific subjects can 

 in no way be so well illustrated as by photography. The lantern 

 has replaced the large diagrams which used to hang on our 

 walls, and the facility with which minute objects can be 

 accurately reproduced by Photography and then enlarged by the 

 lantern proves not only a saving of time and trouble, but 

 introduces a wonderful certainty with regard to such forms and 

 structures as have hitherto only been seen under the [Microscope, 

 and so remained the property of the few. We therefore record 

 our best thanks to the [Members of the flourishing Photographic 

 Section for all it has done for our Society. 



During the past winter, under the Oxford Extension 

 Scheme, we have had a most interesting course of Lectures 

 given by Mr. E. B. Poulton, F.R.S., on " The protective value 

 of colour in animals." These Lectures were well attended, and 

 afforded much sound instruction in a field of research full of 

 interest. Those who were present must have enjoyed hearing 

 so able a teacher. 



Your Committee have met frequently during the past year, 

 and have done all in their power to promote the best interests 

 of the Society by affording every facility for the increase of that 

 knowledge which tends to give fresh interest to the locality in 

 which we live. They trust that their endeavours have met with 

 the approval of the Members to whom they make this Report.
