DUBLIN NATURALISTS' FIELD CLUB. 
October 30.- Conversazione in the Royal College of Science, 
Stephen's Green. This change from the usual meeting place of the 
Club arose from the fact that the Council of the Academy were intro- 
ducing electric light into the Academy House, which was therefore not 
available. At 8.30 the President (C. B. Moffat, B.A.) took the chair, 
and after welcoming the visitors called upon Prof. Carpenter, who 
delivered a short lecture on " Animal Form and Colour." The lecture, 
which dealt with protective coloration and mimicry in the animal world, 
was illustratedby a large series of coloured lantern slides. The remainder 
of the evening was spent in examining the numerous scientific exhibits 
which were on display. The following is a list of the more important : —
