32 REPORT OF THE SECRETARY. 



Among such investigations was one by Mr. L. Fison, in regard to the 

 aborigines of Australia, and an agreement was entered into with liim 

 by which the Institution was to publish it, uniform with Mr. Morgan's 

 memoir. The number of manuscripts in hand waiting for publication 

 prevented Mr. Fisou's article from going to press, and he finally was 

 able to make arrangements at home for its appearance. The paper was 

 accordingly withdrawn and transmitted to the author through Mr. Mor- 

 gan. 



There is now a sufficient number of the quarto memoirs completed to 

 form another volume of the " Contributions," Volume XXIII ; and this 

 will be issued early in the year 1881. It will probably comprise :
