entomological collections. One notable feature that I found 
especially pleasing was the attention bestowed on the sepa- 
rate arrangement of groups of insects illustrating the pheno- 
mena of mimicry and warning colouration, and of seasonal 
dimorphism. So completely had this improvement been 
considered, that it extended to the including of specimens 
of Lepidoptera whose mutilated wings gave evidence of the 
attacks of birds and other insect-eaters—the first instance 
known to me of the recognition by any Museum of the value 
of such injured examples, which have everywhere been re- 
jected as worthless. Prof. Poulton has also succeeded in 
securing several groups of tropical and subtropical species, 
exhibiting mimetic resemblance or common warning colours, 
captured in one locality and on the same day, and thus in 
initiating an invaluable series in evidence of the actual com- 
panionship in life of their wonderfully adapted forms. 
In resigning the Presidential Chair, I desire in the first 
place to thank the Society, and more particularly my col- 
leagues on the Council, for much consideration extended to 
me on the too frequent occasions when my health obliged me 
to devolve the duties of Chairman on one of the Vice-Presi-

Mr. W. F. H. Blandford, who has most kindly aided me 
by preparing the Obituary Notices, and also by undertaking

to recognise that the Society has made more than average 
progress during my two years’ tenure of the Chair, I am 
well aware that I have personally been able to do very little 
to promote this prosperity, and that credit for it is mainly 
due to the unremitting attention given to our affairs by the 
Treasurer and Secretaries. Our experienced Treasurer, Mr. 
McLachlan, I am glad to say, maintains his post as guardian 
of our finances; but it is with sincere regret that we have 
received the resignation of both our Secretaries, Mr. Blandford 
and Mr. Merrifield, who have rendered such able service for 
the last two years. The withdrawal from office of these gen- 
tlemen will not be surprising to any one who, like myself, 
has been Secretary to a learned Society, and knows how large
