NOTES AND EXHIBITS. 



Mr. Baker, on behalf of Mr, H. Smith, showed a specimen of 

 Barytes in Hawkesbury sandstone from Gosford, and he stated that 

 in a paper read before this Society on 29th April, 1891, Mr. Smith 

 had called attention to the presence of Barytes at Marrickville, 

 the first record of the occurrence of this mineral in the Hawkes- 

 bury Sandstone. In a subsequent paper communicated to the 

 Royal Society of N.S.W., attention was again called to its presence 

 in a second locality some considerable distance from the first, and 

 the opinion was expressed that it was laid down contemporaneously 

 with the shale beds, and that its pi'esence would be found over a 

 large area. The specimen exhibited was from the Ballast Quarry 

 not far from Broadwater, 100 or 200 yards from Gosford Railway 

 Station, and from the same formation as the Marrickville speci- 

 mens and from about the same level. It was obtained and pre- 

 sented to the Museum by Mr. Wall. Though the specimen 

 exhibited was from the conglomerate, a specimen of shale with 

 Barytes was also obtained at the same place. The occurrence of 

 the mineral at Gosford suggests the probability that the area from 

 Sydney to Gosford, at any rate, is a portion of a lacusti'ine 

 formation. 



Dr. Norton exhibited a portion of a root of Stenocarpus cunning- 

 hamii, R.Br., showing an extraordinary development of fibrous 

 rootlets. 



Dr. Norton also related a remarkable instance of antipathy to 

 the smell of fish on the part of a horse in his possession. 



Mr. Rainbow exhibited the two sexes of an undescribed Sydney 

 spider (IfepJiila sp.) the webs of which were said to be strong 

 enoueh to catch small birds.
