8 INTRODUCTORY ADDRESS: 



of Photomicrograpliy and the discussion and demonstration of any 

 subjects of interest concerning it." From the first the Society was a 

 success, as evidenced by continual increase of Membership, and this is 

 perhaps due to the wide field in Research, Engineering, Natural History, 

 Industrial and other Processes, in which the Microscope is essential. 

 This is also shown in the diverse nature of the subjects in which 

 individual members are specially interested, but who alike have to 

 record their observations by Photography. Others again are interested 

 purely in the optical equipment of the Microscope and the special 

 problems presented to the photomicrographic worker. The essential 

 importance of correct microscopic technique, especially proper 

 illumination to obtain a correct image, has always been recognised, 

 and great attention has been paid to the mechanical side, as shown 

 by apparatus designed and built by several members and exhibited 

 from time to time. 



Mr. F. Martin Duncan now occupies the Presidential Chair, and 

 Mr. J. E. Barnard was President in 1915-16. A Medal is awarded 

 annually, for the best results in Photomicrography from both the 

 microscopical and photographic point of view. 



The Society meets twice monthly at King's College, and has 

 papers on the many subjects in which the use of the Microscope is 

 essential, together with other meetings of a less formal character 

 for discussion, exhibition of photomicrographs, and apparatus 

 connected with Photomicrography. 



For the foregoing information I am indebted to the Honorary 

 Secretary and Treasurer, Mr. J. G. Bradbury, who has done so much 

 good work on behalf of this useful Society. 



British Science Guild. — The Committee on the Microscope appointed 

 by this Body, with its Chairman, Dr. Walmsley, have also been kind 

 enough to give much useful help with regard to our Symposium. 



It will be seen therefore that the Faraday Society has been 

 successful in enlisting the co-operation and aid of the various special 

 Societies who are also immediately interested in improving Research 

 Work in Microscopy. 



Objects of the Symposium. — The objects of the Symposium 

 are : — 



(a) Improvement in the technique of the Microsco])e itself, 

 including its manufacture. 



(b) Improvement in Lenses including Eye-pieces and Objectives 

 of High Power. 



(c) Improved application of the Microscope for Research in 

 Ferrous and Non-Ferrous Metallurgy. 



AVith these objects all will be in agreement, and if as a result 

 of this Symposium they are successfully carried out and attained, 

 as I am confident will be the case, our gathering will be not only
