NATURAL SCIENCES OF PHILADELPHIA. 285 



Committee have not been able, however, to exhibit the families and genera in 

 their proper sequence, on account of the over-crowded condition of the cases, 

 but this can be readily remedied at any time tbat we possess more space. 



We also regret the want of space exceedingly, because it debars us from ex- 

 hibiting those interesting geographical series, which to a naturalist are not less 

 instructive than a collection of species ; enabling us to acquire a knowledge 

 of the limits and variations of species, as determined by climatal and other in- 

 fluences. 



Nearly double our present space is required for the proper exhibition of the 

 collection which we already possess, and a small appropriation to publish a 

 catalogue, would enable us to increase largely and rapidly. 



While we deem it but right that the Academy, through you, should be made 

 acquainted with our wants, the Committee forbear to press them at this time, 

 being well aware that other departments of the collection require the first, and 

 immediate pecuniary aid of the Academy. 



Respectfully yours, 



GEORGE W. TRYON, Jr., 



For Committee on Conchology .
