 objects and promoting the prosperity of the Society, moved. That an es- 

 pecial vote of thanks be given to Mr Tod, for the great ability and un- 

 wearied zeal with which he had so long discharged the duties of Secre- 

 tary, and which Dr Maclagan felt assured, the Society would consider it 

 to be their duty to acknowledge by some further mark and memorial of 

 their approbation. 



Sir John Graham Dalyell, in seconding the motion, expressed his en- 

 tire concurrence in the opinion entertained of Mr Tod's merits, and pro- 

 posed that it be remitted to the Council of the Society, to consider and
