Wadsworth.] 180 [April 16, 



Wadsworth maintained that Foster and Whitney were the only 

 authors who had written correctly on Lake Superior geology ; also 

 I may further cite Irving's charges that Wadsworth did not 

 dare to point out wherein he disagreed from Foster and Whitney, 

 and that he did not render due credit to Pumpelly and Marvine. 

 All of the above statements of Irving I pronounce entirely incorrect, 

 as any one can see who cares to read my work on Lake Superior 

 geology with care. Therefore I need not discuss the matter further 

 except in Marvine's case to simply say that I was the first, so far 

 as I am aware, to publicly call attention to the great value of his 

 Lake Superior work. While I frankly disagree from Professor 

 Irving in the above points and some others 1 , I yet recognize the 

 great merit of his work in other directions and find myself there 

 in full accord with him. 2 



Annual Meeting, May 7, 1884. 



The President, Mr. S. H. Scudder, in the chair. 

 The following annual reports were presented : 



Report on the Museum. By A. Hyatt, Curator. 



As in former reports, we have still to lament the melancholy 

 state of our finances and our inability to do work such as this 

 Museum is fitted to do for the benefit of the community. 



We wrote last year that we hoped to be able to establish loan 

 collections for circulation, basing our idea of the need of such col- 

 lections upon the constant demands for specimens which are made 

 but have to be denied by us. We have held for years past that the 

 time must come when people would realize the necessity of seeing

2 Conceruing the replacement of feldspar by prehnite in coarsely crystalline diabase, 

 to which attention is called by Irving in the final report (pp. 40, 43) his case may be 

 strengthened by the fact that like change in a very coarsely crystalline diabase of Mas- 

 sachusetts was pointed out by the writer in 1877, Proc. Bost.Soc. Nat. Hist., 1877, xix, 

 228, 229.
