Dr. Lawson then gave a short lecture *' On the Chemical relations of

 address given by the Chairman. 



After this there was a promenade in the Museum, and refreshments in the 

 Office of the Inland Revenue, which had also been kindly vacated for the 

 occasion by the Inspector and Collector Messrs. Patterson and Tupper. 

 Here Mrs. Warren and Miss Clarke provided for and ministered to the 

 wants of the Assembly. Mr. S. A. Porter, Organist of St. Paul's, and a 

 select band, kindly furnished the music for the Conversazione — performing 

 select pieces at intervals during the evening. 



The Institute is under great obligations to Dr. Warren, in undertaking 

 the management, for the trouble taken, and the zeal displayed, which conse- 

 quently resulted in a very excellent and delightful Conversazione.
