11 



departments of Natural History established hereafter, together 

 with such collections as, even with the most rigorous sifting, 

 each will accumulate. The natural growth of comparative 

 anatomy, ethnology, and archaeology, and of the geological, 

 geographical, and other biological departments, which will 

 naturally centre in the Natural History square of the Univer- 

 sity, will tax its capacity to the utmost, if they have in the 

 future a growth at all commensurate with that of these depart- 

 ments up to the present time.
