THE PRESIDENTIAL ADDRESS ai 



that the conclusions on warning colours and mimicry have been 

 immensely strengthened and confirmed by the later observations of 

 Guy Marshall, W. A. Lamborn, St. Aubyn Rogers, Hale Carpenter, 

 V. G. L. van Someren, C. F. M. Swynnerton and others in Africa ; 

 by the experiments conducted by some of these naturalists, and also 

 by H. B. Cott and R. Carrick, and in the United States by Morton 

 Jones, 



It is interesting to remember that a paper by two American 

 entomologists ^^ was among the first to accept and support by fresh 

 observations the conclusions brought forward by H. W. Bates in 

 his great memoir on the mimetic butterflies of the Amazon Valley ,^^ 

 and that one of the authors treated the same subject more completely 

 in a later paper 2* much appreciated by Darwin. ^^ 



It is also important to remember that the above-mentioned con- 

 clusions have been reached by the study of marine animals no less 

 than terrestrial, as was shown by Herdman in his address to Sec- 

 tion D at Glasgow in 1901, and by his experiments communicated 

 to the same Section at Ipswich in 1895 ; also that Garstang, with his 

 very long and intimate experience of marine life, adopts the same 

 interpretation of colour and form with the associated attitudes and 

 movements. 



If time permitted it would be possible to speak of numerous 

 papers on mimicry and the related subjects which have been brought 

 before our meetings. It is impossible to attempt this now, but 

 many will feel with me that the name of the late Dr. F. A. Dixey 

 should not be forgotten — one who attended so regularly, so often 

 read papers at our meetings, presided over Section D at Bournemouth 

 in 1919, lectured at Leicester in 1907, always giving the results 

 yielded by the study of his favourite insects, and their interpretation 

 by the theory of natural selection ; also one who delighted in the social 

 gatherings of his Section, where his rendering of Widdicombe Fair 

 will be long remembered. 



In my concluding remarks I am anxious to refer to a very 

 interesting and encouraging subject — the feeling for animals and 

 the care for their welfare to-day, as contrasted with the treatment 

 they received a hundred years ago and even in the youth of many 

 among us. Only last autumn The Times of October 12, reported 

 that 1 ,000 swallows had arrived at Venice ' sent there by bird-lovers 

 from Vienna and Munich in order to save them from the effects of
