ORDINARY MEBTINGS 
June d5th.—The President (Mr. Shiress) in the chair, and a 
good attendance. Mr. Lippmann and Misses O’Hanlon and Devis 
were duly elected members. 
Master Howell showed Persoonia salicina thickly infested 
with galls of Apiomorpha munita vesulting in these being 
dwarfed in size, none of them reaching the usual dimensions. 
Miss Crispo branchlets of Casuarina Cunninghami with both 
male and female inflorescences, and also galls of Cylindrococcus 
spiniferus. 
Mr. A. Chisholm gave an interesting address on birds, deal- 
ing especially with their nesting habits. He divided them into 
three classes, those which nest on the ground, in forks of trees 
and those which build suspended nests. The lantern slides with 
which the lecture was illustrated showed the patience and skill 
of the photographer. The slides of jungle nests were particular- 
ly fascinating, while those which gave some idea of the beauties 
of Queensland National Park were also much appreciated. Many 
instances on the part of the birds to be friendly were adduced. 
The evolution of nest building was exemplified by a series of 
slides, from the few sticks of the Torres pigeon to the claborate 
structures of such birds as the lyre bird, robin, ete. On the 
motion of Messrs. Froggatt and Finckh a cordial vote of thanks 
was carried. 
July 3rd.—The President (Mr. Shiress) in the chair, and 
there was a good attendance. A paper by Rev. Archdeacon 
Haviland was read, on “The Castlereagh.” Mv. Cheel, on beball’ 
of Rev. H. Rupp, read a paper entitled “Notes on the habits of 
certain Orchids.” 
Mr. Forster exhibited Rapanea variabilis collected at the ex- 
cursion to Lugarno Ferry, also 23 paintings of plants collected 
at the same excursion. Mr. Winckh gave an interesting account 
of the tameness of a shrike thrush (Collwricinela harmonica) 
which took food from his hand in his garden at Mosman.
