PEEFACE. 



The Council has to express its great regret that it 

 was impossible to issue any Transactions before, as 

 from the unexpected withdrawal of the Government 

 Grant in 1868, there were no funds to do so, or even 

 to pay the printer for the volume last issued, 



A sum having now been granted by the liberality 

 of the present Government, the present volume has 

 been prepared as soon as the great difficulty in 

 collecting the papers rendered it possible. Unfor- 

 tunately some are altogether wanting; several having 

 been returned to their authors, as there was no 

 immediate possibility of their being printed, and 

 some of them are not recoverable. 



There is now a prospect of greater regularity in 

 the issue of the Transactions for the future.
