REPORT OF THE GEOLOGICAL SECTION. 



Fo7- the term ending May, iSgg. 



The Section submits with pleasure this, their annual report, 

 feeling that a steady onward march has has been maintained during 

 the past year. 



Although the Section cannot announce many new discoveries 

 in this vicinity since our last report, yet it can assure the Association 

 that substantial progress has been made in the collection of speci- 

 mens, some of which reveal varieties of well-known species, exhibit- 

 ing peculiarities which might lead the novice to believe that he had 

 discovered a new species, and for which he would, as in duty bound,

 modern Lingula, thereby proving that through the countless ages 

 this species has preserved not only the shape, color and habits of its 

 palaeozoic ancestors, but also the same mode of propagating its 

 species. The specimen was obtained from the Clinton formation 

 here. 



During the year many new specimens have been added to the 

 Museum. The crowded condition of the cases does not afford any 

 opportunity to display the newly acquired fossils to advantage. 



During the year the Museum has been kept open to the public 

 on Saturday afternoons, so that any persons desiring to avail them- 

 selves of the use of specimens in the Museum for comparison or 

 study were free to do so by themselves, or have the assistance of 

 Col. C. C. Grant or Mr. A. E. Walker, if required. 



The Section was gratified to learn that the Museum of the 

 Hamilton Association was pronounced by competent authority to be
