During the year the Council carefully considered the Rules of the 

 Society, and came to the conclusion that it was advisable to revise them, 

 and the amended code, adopted by the Society on the 21st May, is now 

 in force. The chief alterations consist in the numerical increase in the 

 Council, the admission as corresponding members of residents in this 

 Province at a distance from Adelaide, and the creation of the new class 

 of Associates. 



Several changes in the Council have taken place, due in part to the 

 adoption of these Rules, and in part to the resignation of the Honorary 

 Secretary, Mr. W. C. M. Finniss. On the 18th June Mr. Walter Rutt, 

 C.E., was elected Honorary Secretary ; Mr. T. D. Smeaton, whose office 

 as Past Vice-President was abolished, was elected Vice-President ; and 

 Mr. D. B. Adamson a Member of Council. 



It is with deep regret that the Council record the death of Mr. 

 John Howard Clark, one of the founders of the Society, and for many 

 years one of its most active members. Mr. Clark filled successively for 

 a considerable time the offices of Secretary and Treasurer ; and although 

 of late ill-health prevented him from taking any active part in the pro- 

 ceedings of the Society, his interest in all matters connected with science 

 and literature remained to the last unabated. 



The number of members of all classes on the Society's roll at the 

 commencement of the past session was 103, and the present number is 

 101, as shown in the annexed table. The large number of apparent 

 resignations is due to the fact that the names of several gentlemen, who 

 have for some years discontinued their subscriptions without formally 

 sending in their resignations, are now omitted : —
