wounds in tlie bark of growing trees, from stumps left in the ground— very 

 sparingly, iiowever, from the small shrubby species, and not in great quantity 

 from the tree; it is semi-transparent, brittle, and has a slight resinous taste; 

 dissolved in turpentine it forms a Tarnish, but sufficient trial has not been 

 made of its value in this respect; it burns readily, with a slow, steady flame.

Lieut. Clarke, R.E., read a paper by Sir W. T. Denison on the 

 destruction of piles by the Teredo navalis, as evidenced in those 

 recently taken up in forming the entrance of the new dock. His 

 Excellency recommended that every opportunity should be seized of 

 making record of any fact proving the liability or non-liability of 

 various timbers we possess to be attacked by this insect. A turbid 

 and unsettled condition of water is thought to retard or even to 

 prevent the operations of the insect ; and some appear to consider 

 the Huon pine exempt from its ravages. 



After a conversation, in which Dr. Agnew, Lieut. Clarke, Mr. 

 Mitchell, Dr. Officer, and others took part, it was resolved, gn the 

 motion of Mr. Hone, seconded by Mr. Hort, that the thanks of the 

 Society be given for the various papers and donations, and the 

 meeting broke up.
