396 NOTKS AND EXHIBITS. 



it flew towards Darling Harbour, then circled round, passing 

 Milson's Point, and settling down again on the water in Farm 

 Cove. During August one of these birds was received by the 

 Trustees of the Australian Museum which was captured alive by 

 Mr. R. S. Thomas, of South Clifton. Of curious nesting sites of 

 the Rock Warbler, Origma rubricata Latham, Mr. A. F. Hull 

 informed Mr North that a pair had built their nest round a 

 piece of string hanging down inside from the roof of a tent at 

 Freshwater, Manly. This tent, the entrance to which was 

 partially concealed by a rock shelter, was occupied from Saturday 

 to Monday, and every other night by several youths, but the 

 birds, unconcerned at their presence, had finished the nest, and 

 the female had since the 17th inst. been sitting on a full com- 

 plement of eggs. Last year Mr. Herbert E. Ross informed him 

 a pair had built their nest in a small cave that had been fitted 

 up as a dark-room for photographers, in the rocky and spacious 

 grounds of a well known resort at Medlow on the Blue Mountains. 

 At Lane Cove Mr. Arthur Muddle found a nest last year 

 attached to the timbers beneath the verandah of a waterside 

 cottage, and in the same locality several seasons ago Mr. Edgar 

 R. Waite saw a nest, containing young, attached to the roof 

 inside a bathing-box at Longueville. 



Mr. H. I. Jensen exhibited (I) hand-specimens and thin 

 slices of glaucophane schist from Mt. Mee, in the D'Aguilar 

 Range, Queensland. This rock occurs associated with actinolite 

 schist, anthophyllite schist, uralite and other amphibole schists, 

 all of which represent a highly metamorphosed Palaeozoic lava or 

 tufif. They are interbedded with highly metamorphic granulites, 

 phyllites and mica schists, probably of Devonian age. For 

 comparison thin slices of riebeckite trachyte from Mt. Tibrogar- 

 gan, and arfvedsonite-cossyrite trachyte from Ngun-Ngun, in 

 the Glass House Mountains, were exhibited. The occurrence of 

 glaucophane, which is closely allied to riebeckite in chemical 

 constitution, in the same district as the alkaline trachj^tes, but 

 in highly altered lavas of much greater age, is an interesting 

 piece of evidence that this district was an alkaline province even
