to December, 1901, is now in press, and will be distributed to 

 the members within a very short time. 



Volume II, Part 3, of the Memoh's, entitled " Palaeontolog- 

 ical Notes," by Bashford Dean, 4to, pages 87-123 ; plates 3 to 

 8, has also been printed and distributed. This Memoir was in

When the Editor was appointed, in December, 1900, the 

 funds of the Academy available for publication had been ex- 

 hausted, and the year was begun with a large deficit. During 

 the year the accounts have been straightened out, the deficit 

 met, and the year will close with practically a clean balance 

 sheet. Respectfully submitted, 



Charles Lane Poor, 



Editor. 



PRESIDENT'S ADDRESS. 



Measurement and Calculation. 



In my address of a year ago I sought, in a summary way, 

 and by concrete illustration, to indicate how science originates 

 in and advances with observation and experiment. I would now 

 invite your attention to a similar consideration of the role which 

 measurement and calculation play in the higher developments 

 of science. 



All sciences are at first qualitative. They pass in their 

 growth from the fact-gathering stage of unrelated qualities to 

 the orderly stage of related qualities and thence upward to the 

 stage of quantitative correlation under theory. Such, at any 

 rate, has been the course of all sciences hitherto developed, and 

 it seems safe to predict that such will be the course of those 

 which may arise in the future. The recognition of this fact is 

 of prime importance. It helps us to understand the great rela- 

 tive diversity in perfection among the sciences ; it affords a 

 basis for rational optimism with respect to the continued 

 progress of science ; and it ought to make the specialists of the 

 older sciences less contemptuous than they sometimes are in 

 their attitude toward the newer ones which have not yet passed 

 the "rock-naming and bug-hunting stage,"
