G. O. Tepper read a translation from a German periodical, 

 Das Echo, dated April 30, 1914, dealing with the fact that 

 the chlorophyll of plants is a mixture of two closely-allied sub- 

 stances, in the proportion of one molecule of chlorophyll B to 

 nearly three molecules of chlorophyll A, and that an intimate 

 relation existed between chlorophyll and haemin, the colouring 

 matter of animal blood. In the conversation which followed 

 Dr. Pulleine mentioned that green vegetables were useful in 

 some forms of anaemia, and that chlorophyll was now employed 

 medicinally in the treatment of anaemia. 



Paper. — "'Some Moths from Melville and Bathurst Islands

 M.D., F.E.S. 



Ordinary Meeting, August 13, 1914. 



The President (J. C. Verco, M.D., F.R.C.S.) in the 

 chair. 



The President commented on the recent visit of the 

 British Association for the Advancement of Science to Ade- 

 laide, and gave details of the various Fellows of the Society 

 who had conducted excursions to places and objects of interest. 



Nomination. — David G. Darroch, Australian United 

 Paint Co., Port Adelaide, was nominated as a Fellow. 



Exhibits. — Mr. H. G. Stokes, F.G.S., exhibited speci- 

 mens of radio-active ore and associated minerals from Mount 

 Painter, in the Flinders Range, including small samples of 

 crude radium barium sulphate, and of sodium di-uranate, 

 obtained in the treatment of the ore. Several members of the 

 British Association, who had examined these minerals, had 

 pronounced them to be the most beautiful of their kind that 

 they had yet seen. Considerable interest was taken in this 

 exhibit, and many questions were asked, to which Mr. Stokes 

 replied, and promised to exhibit a further series at the next 

 meeting. Mr. A. M. Lea exhibited two cases of leaf -eating 

 beetles of the genus Paropsis, several of which are frequently 

 mistaken for ladybirds. Some species are remarkable for 

 brilliant golden or silvery spots, which disappear shortly after 

 death; also some larvae of tortoise beetles, which have the 

 curious habit of covering themselves with their own excreta, 

 special processes being provided for this purpose.
