The retiring president, Mr. E. H. Lock, F.R.H.S., then 

 delivered a most instructive and interesting address on ''Dralna 

 in Nature." His discourse was much appreciated by the 

 large audience present. 



On October 20, 1914, an Exhibit Evening was held, and 

 a fine collection of material was tabled by members. Mr. A. 

 M. Lea exhibited two cases of New Zealand insects. A New 

 Zealand chiton, of unusual dimensions, was shown by Mrs. 

 Mellor, while a number of mineralogical specimens were shown 

 by Mr. P. H. E. Runge (Hon. Secretary). Mr. W. J. Kimber, 

 with the aid of specimens, gave many interesting facts about 

 "The Life History of the Hermit Crab," and Captain White 

 (Chairman) laid out on the table a beautiful collection of 

 South African birds. 



April 20, 1915. — This, the first of the winter series of 

 monthly meetings, was devoted to exhibits. Mr. R. Llewellyn 

 exhibited a beautiful collection of cowrie shells, including many 

 species obtained in various parts of the world. A collection of 

 fossil shells, obtained at a depth of 400 feet during boring 

 operations on the Adelaide plains, was exhibited by Mr. 

 Ising. At the Chairman's request, Mr. Riddle explained the 

 geological significance of the deposit. Mr. A. R. Riddle 

 exhibited a collection of gypsum obtained from Yorke Penin- 

 sula. Many of these showed great variations in twinning, 

 whilst others, which simulated true twin crystals, were simply 

 intergrowths. The massive form from Marion Bay, as well 

 as the granular variety or "seed gypsum," from the immense 

 deposit at Lake Fowler, were shown. On behalf of Miss 

 Roberts, Mr. Riddle exhibited a so-called "fossil mushroom" 

 from Brown's Well. Far from being a fossil, the specimen was 

 quite a present-day form known as Laccocephcdum basilapi- 

 loides. This fungus grows in sandy soil, and by reason of its 

 hyphae being glutinous, the sand grains become cemented 

 together. This, together with the woody nature of the fungus, 

 gives the "fossil"-like appearance. Captain White (Chair- 

 man) exhibited a number of South African birds, and referred 

 to their nesting and other habits. His rem.arks were illustrated 

 by a number of beautiful slides taken in South Africa. Mr. 

 A. M. Lea, F.E.S., gave several interesting facts about a
