A considerable amount of labour is devoted to the yearly reports, 

 which are a special feature of the Department. The researches 

 conducted in the Department or upon its material are published 

 through various scientific societies and journals, but separata 

 are struck on and bound, and issued for private circulation 

 from time to time. The seventh \'olume of the Report appeared 

 in 1 910, and the materials for an eighth are in hand.
