 drew up an interesting report on the mineral constituents of gizzard grits iu

 History Department, Royal Scottish jNIuseum, was appointed iu 19U9 to undertake

 a complete list of the insects found on the moors, but also reported upon 

 those eaten by the Grouse as shown by an examination of their crops and 

 gizzards. The result of his work is published in the " Annals of Scottish Natural 

 History" for July 1910, and in chapter iv. and Appendix E of the present

 sole source of income for the Inquiry, and without which nothing could be done ; the 

 control of this Fund further rested in him. He also got together and organised 

 the three hundred and sixty local correspondents, he drew up all the various tables, 

 forms, etc., with which these correspondents were supplied, received the answers to 

 the questions asked, collated and tabulated not only these answers but the verbal
