 The Peesident in the Chair. 



The President delivered the annual address. In addition to the 

 usual resume of the papers read at the Society's meetings he gave 

 an account of tlie history of the Society and the reasons which had 

 induced the Council to gipe up publishing their transactions in a 

 separate form, and merge them in a popular monthly journal. He 

 also stated that since this arrangement had been made, three mem- 

 bers had been added to the ranks of the Society. The address was 

 rendered unusually interesting by a communication of Professor 

 Lister, of Edinburgh, giving an account of the scientific career of 

 his late father, Joseph Jackson Lister, with especial reference to 

 his labours in the improvement of the Achromatic Microscope. 



It appears from the Treasurer's account that the Society has

 resolved in future to stop the refreshments at the evening meetings.
