Alfred E. C. Selwyn, Esq., F.E.S., F.G.S., 



Director of the Geological Survey of Canada. 



Sir, — I herewith beg to lay before you the results of the work carried 

 out in the Laboratory of this Survey during the past year. It embraces 

 all such analyses as were considered likely to prove of general interest. 

 As will be seen, attention has been mainly directed to the examination 

 of such minerals, etc., etc., as promised to prove of economic value. 

 Such analyses or assays as have been made by my zealous Assistant, 

 Mr. Frank D. Adams, have in all instances been duly credited to him ; 

 those not otherwise designated having been made by myself. 



I have the honour to be, 



Sir, 



Your obedient servant, 



CHRISTIAN HOFFMANN.
