many years, amongst this little-known group. 
Mr. J. S. P. Ramsay, on August 20th, 1923, gave an instructive 
lecture on Nature Photography, illustrated with lantern slides. 
He told of the many obstacles to be faced before good results 
can be obtained, and exhibited many ingenious devices invented 
by himself to overcome these. The slides illustrated the actual 
taking of some of his subjects from the beginning of the opera¬ 
tion to the final result, and in many instances showed his in¬ 
ventions in actual use. 
On September 21st, 1923, Mr. N. W. Cayley delivered a shoit 
lecture on Pigeons, illustrated with his water-colour drawings 
of every known Australian species, including the two species 
of the genus Globicera, recently added to the list by Mr. G. M. 
Mathews. Mr. Cayley gave his personal experiences with many 
species, especially the Fruit Pigeons; their food and nidification, 
and mentioned the economic value of the Wpnga and Nutmeg 
species.

lecture on Quail, illustrated by water-colour drawings lent by 
Mr. N. W. Cayley, and a mounted specimen of a Plain-Wanderer 
from his private collection. Brief references were made to the 
species of which the lecturer had no personal observations, and 
many items of interest given on those he knew. Special mention 
was made of information recently received by him relating to 
the Plain-Wanderer; the specimen exhibited was procured quite 
recently from Victoria. 
On February 15th, 1924, Mr. Tom Iredale delivered a lecture 
on Australian migrants, a group of birds of which very little is 
known, especially in Australia. He dealt at length with their 
distribution, and explained that Australia was the northern limit 
of the Antarctic breeding species, including Petrels and Alba¬ 
trosses, a few of which were only casual visitants. He also de¬ 
scribed the routes taken by the Arctic breeding Waders on their an¬ 
nual migration to Australia and the Islands of the Pacific. Mr. Ire- 
dale exhibited the young of the Kentish Plover, Peewit and Ring 
Plover, and drew attention to their similarity to the young of the 
Red-capped Dotterel, Spur-winged Plover, and Hooded Dotterel. 
At this meeting Mr. C. Coles exhibited the eggs of the Magnificent 
Bird of Paradise, laid in captivity, the first known record of the 
eggs of this species. He also gave some interesting notes on the 
habits of the species in captivity.
