XXIV PROCEEDINGS. 



(2) The Blue Crab (Callinectes sapidus Rathbun): Extension 

 of its Range Northward to near HaHfax, N. S. -By Harry 

 Piers, Curator of the Provincial Museum, Halifax. (See 

 Transactions, page 83). 



On motion from the Chair, seconded by Prof. McIntosh, 

 it was unanimously resolved that the Nova Scotian Institute 

 of Science desires to place on record its profound sense of loss 

 in the death from pneumonia on the sixth day of January, 1920, 

 after an illness of eight days, of Professor Ebenezer Mac- 

 KAY, Ph.D. (J. H. U.), MacLeod Professor of Chemistry in 

 Dalhousie University. He was a member of the Institute 

 from 1889, from 1907 to 1910 its President, from 1899 a member 

 of the Council, and for the last few years the efficient Corres- 

 ponding Secretary. As he was only in his fifty-sixth year, full 

 of vigor, incessantly active, happy and hopeful; an ideal trainer 

 of students in science; the most tactful and generous of col- 

 laborators; his death is a profound loss to the Nova Scotian In- 

 stitute of Science, as well as to Dalhousie University and the 

 science of Chemistry in Canada. Even in the affairs of the 

 city of Halifax his usefulness in aiding many public improve- 

 ments has created demonstrations of sorrow for his loss which 

 have rarely fallen to the lot of an educationist. 



It was further resolved that an obituary notice and portrait 

 of the late Dr. Mackay be inserted in the proceedings. (See 

 page xxvii.) 



Prof. D. S. McIntosh reported that he had received an in- 

 teresting specimen of Inyoite from Hillsboro, New Brunswick, 

 a mineral which formerly had only been reported from Cali- 

 fornia, U.S.A.
