colonies of a very limited extent, because, when examining the 

 rock beds of the same horizon in which these specimens are 

 usualh' found in considerable numbers, and although not far 

 removed from that spot where they are quite numerous, 

 probably a hundred feet or so, they appear to be almost entirely 

 absent, thus demonstrating that there was not a uniform distri- 

 bution of this variety of sea life on the bed of the ocean even 

 where the depth of water was favorable to their existence. The 

 Hainilton collector has been distinctly favored because of this 

 escarpment showing the depth of three distinct formations 

 and the quarrying process of the different strata which has 

 been going on for many years, but more extensively in the 

 Niagara formation, revealing the peculiar forms of life which 

 have been entombed therein during the process of deposition. 

 The collector has had the privilege of examining and com- 

 paring the various forms of fossils as to their variety, their 

 fuller development, and the effect which conditions of deposit 

 during flood or ebb tide would have upon the distribution of 

 these fossils throughout the strata marking the several epochs 

 in the geological, as well as the palaeontological, life in the 

 different beds which compose the separate formations. 



Letters have been received from the directors of different 

 museums expressing their appreciation and thanks of the 

 governing Councils for the specimens sent to them by our 

 most active and energetic member Colonel C. C. Grant. Pro- 

 fessor W. D. Lang, of the British museum, acknowledges the 

 receipt of 129 specimens of fossils from the Niagara formation 

 and Hudson River group obtained at Hamilton and on the 

 lake shore at Grimsby, among which were specimens of 

 Cladopora and Lichenalia new to science. Professor J. F- 

 Whiteaves, acting director of the Geological Survey of 

 Canada, also acknowledges the receipt of fossils from the 

 same localities. Professor Clark, state Geologist of the State 

 of New York, also acknowledges the receipt of fossils. 

 Information has been received from Ottawa that the collection 

 of bryozoons from Hamilton and Grimsby have been for- 

 warded to Dr. Brostter, of the Smithsonian Institute, in
