THE FOLLOWING PAPERS WERE READ I 



1. "On a new species of Eucalyptus from Northern Queens- 



land," by J. H. Maiden, f.l.s. and R. H. Oambage, l.s., 



F.L.S. 



2. "Notes on Eucalyptus, with description of new species,"" 



No. II, by J. H. Maiden, f.l.s. 

 Remarks were made by the President and Mr. R. H* 

 Oambage. 



3. "The occurrence of Trimethylamine and its origin in the 



Australian Salt-bush, Rhagodia hastata R. Br.," by 

 R. W. Ohallinor, f.i.c., F.C.S. 



This plant belongs to the family Ohenopodiacese and is- 

 the common species grown in the gardens around Sydney. 

 The investigation was carried out in order to locate, if 

 possible, the constituents which give rise to the volatile 

 substance having a strong herring-brine odour. Trimethyl- 

 amine was obtained on distilling the fresh branchlets with 

 caustic alkali, the amount obtained in this way being 

 equivalent to 0*012 per cent. Analysis of the plant was 

 undertaken by a method similar to that of Schulze, and a. 

 basic substance isolated, the hydrochloride of which decom- 

 poses at about 220° O. with evolution of trimethylamine* 

 This salt resembles choline hydrcloride very closely in its 

 chemical reactions, but differs from it in being non-deli- 

 quescent and considerably less soluble in absolute alcohol* 

 The double platinum salt contains 30*68 per cent, of platinum
