NOTES AND EXHIBITS. 



Mr. D. G. Stead exhibited examples of the Blue-Eye, Pseudo- 

 mugil signifer Kner, from Wamberal Lagoon, N. S. Wales, living 

 in both sea-water, and pure, fresh water. These were part of a 

 number ol)tained, during April, from the lagoon, at a spot where 

 the water was "sweet" or brackish. These were brought away 

 in that water, and, on April 19th, one was placed in an aquarium 

 of sea-water (of about three years' standing), and the others were 

 put into a freshwater aquarium. All had done well up to the 

 present; the one in salt water, equally with those in fi'esh. This 

 is an interesting experiment, inasmuch as it demonstrates the 

 power of this little species to withstand sudden changes in its 

 surrounding element. The coastal lagoons are very rich in this 

 species, and these lagoons become pi-actially fresh, and very salt 

 alternately; it is, therefore, greatly to the advantage of this 

 (and other species of aquatic life present) if they can adaj^t 

 themselves to the varying conditions. 



Miss Hynes exhibited some excellent diagi'ams of characteristic 

 native plants, reproduced from drawings by Mrs. Ellis Rowan, 

 portion of a series now in course of publication for the Depart- 

 ment of Public Instruction, for u.se in the public schools Also 

 a badge representing the Waratah, for field botanists, reproduced 

 from a drawing by the same artist 



Mr. H. L. White sent, for exhibition, a skull of the Native 

 Bear, showing an extensive osseous growth commencing near the 

 base of the skull and extending into the eye-cavity. From about 

 1875 to 1890, Native ^ Bears ( Phascolarctus cinereus) became 

 exceedingly numerous in the neighbourhood of Belltrees, Scone. 

 They- eventually killed nearly all the Redgum-trees growing along 

 the rivei'-l)anks. From 1890 onwards, a marked decrea.se was
