DELEGATE'S REPORT to CORRESPONDING SOCIETIES 

 COMMITTEE OF BRITISH ASSOCIATION. 



RARE OLD CHESTER. 



The Sixth Monthly Meeting was held in the Museum on 

 25th April, the President, Mr. R. J. Welch, M.R.I.A., in the 

 chair. The following report from the Club's Delegate, Mr. F. 

 Balfour Browne, M.A., was presented. The meeting of the 

 British Association was last year held in Sheffield, and the 

 Conference of Delegates of the Corresponding Societies took 

 place there also, there being two meetings, one on September 1st 

 and the other on the 6th. 



The first meeting opened with an Address by the Chairman, 

 Dr. Tempest Anderson, and he gave a demonstration of a method 

 of optical projection with an instrument invented by himself. 

 This apparatus, the total cost of which is about ^20, projects 

 opaque flat objects right way up and right side forward upon a 

 screen. Dr. Anderson explained that his chief difficulty had been 

 to find a suitable protection against the intense heat produced by 

 the four very powerful electric arc lamps which are necessarily 

 fairly close to the object, there being no intervening condensers. 

 A water tank with glass sides is the only screen at present, and 

 Dr. Anderson seemed to think it would prove sufficient. A 

 considerable amount of light is lost since it is first reflected 

 from the object through a rapid portrait lens placed vertically 

 above the object, and thence it is deflected to a horizontal 

 direction by means of a mirror, and thus reaches a vertical screen, 

 but Dr. Anderson's instrument showed coins, medallions, and 

 fiat geological specimens excellently. 



I was then called upon to move "That a Committee of 

 Biologists be formed to recommend the adoption of a definite 

 system on which collectors should record their captures." At the 

 previous meeting of the Delegates, held in London in October, 

 1909, I had referred to this subject in commenting on Professor
