March L5, 



but this is not the place to rehearse them, were I qualified 

 to do so. I simply call attention to them as a good exam- 

 ple of scientific co-operation, and especially as an illustration 

 of the mode by which an academy endowed by the courtier 

 Rumford, more than eighty years ago, and a university, re- 

 cently founded by Hopkins, of the Society of Friends, are 

 able to unite in the discovery and publication of scientific 

 truth. 



Before I close, Mr. President, may I be allowed to add 

 one more remark? There are three neighboring cities which 

 it seems to me have not yet done what they might for the 

 intellectual advancement of this country. I refer to Balti- 

 more, New York, and, you will pardon me for adding, 

 Philadelphia. They have good institutions, they have 

 learned men, they have great wealth ; but they need stronger 

 and closer combinations than now exist, — better organiza- 

 tion for the advancement of learning. We may hope that 

 with recurring prosperity, increasing vigor will be shown 

 in their academies and universities. 



In such activities there may be emulation, but there 

 should be no rivalry ; for, as the forts which guard the 

 Chesapeake, the Delaware, and the Bay of New York sup- 

 port one another, so these three great cities may strengthen 

 and encourage each other by the firm establishment of in- 

 stitutions for the protection and defense of society against 

 ignorance, bigotry and pretense. Sure that the central city 

 of the trio, the intellectual and financial center of the Key- 

 stone State, will do its part, — I beg leave, in conclusion, to 

 offer this sentiment : 



The American Philosophical Society and the University 

 of Pennsylvania - , may they shine as & Stella duplex through 

 cent mil- i' i come.
