The difference between these elements and those obtained 

 by Mr GORDON and Mr INNES is very considerable. Dr OLBERS 

 remarks, that the observations might have been reduced with 

 greater accuracy ; and he adds, that we may perhaps expect ad- 

 ditional ones from Sir THOMAS BRISBANE or Mr DUNLOP. D. B.
