ABSTRACT OF PROCEEDINGS. xll. 



Mr. R. T. Baker, f.l.s., exhibited specimens of timber of a 

 new Casuarina recently described by him. It is known throughout 

 its distribution — from the Darling River to Main Dividing Range 

 — as " Belah." The timber is pale coloured, very hard and much 

 resembles Hornbeam of Europe in appearance and texture. 



Mr. H. G. Smith, f.c.s., exhibited a remarkable Eucalyptus 

 oil. Owing to the large quantity of eudesmol present, this oil 

 solidified shortly after being obtained from the still. Eudesmol 

 is the solid camphor of Eucalyptus oil. 



He also exhibited Graptolites ( Diplograpsus sp.) in slates, 

 obtained four miles from Cadia, N. S. Wales. These graptolites 

 were found by Mr. R. H. Cambage, and the locality recorded is 

 only one hundred and fifty miles of Sydney. 



Dr. F. H. Qqaife showed specimens of analysing crystals. 

 These act like tourmalines, that is, let a ray vibrating in one of 

 their axes pass, and check all the others proportionally more as 

 their azimuths approach the perpendicular to the first ray. Hence 

 they shew white or partial light or black, without an analysing 

 prism. A quartz of proper thickness causes varied colours to 

 appear in the crystals, according to their thickness, when placed 

 behind them. Notable specimens are citric acid, boracic acid, 

 herapathite or iodosulphate of quinine, platino-cyanide of mag- 

 nesium, etc., etc. Several of these were shown. 



Mr. Grimshaw exhibited a large collection of fulgurites ranging 

 from-iV ' — If in diameter, found on the sand hills at Kensington. 



Exhibits were shewn by Mr. Hamlet — a collection of photo- 

 graphs of the human stomach in cases of poisoning — and also by 

 Prof. Liversidge. 



The meeting was then adjourned to the first Wednesday in 

 December, and an informal Conversazione was held.
