H. G. FORDHAM — OX RECORDING ERRATIC BLOCKS. 165 



boulders are valuable, and a fracrmcnt, sufficiently large for the 

 iclentitication of the rock, sliould be obtained. AVhere a boulder 

 has any local name, or history, this should also be added to its 

 dcscri]ition. 



I trust the members of the Society will feel it to be their duty 

 to add, as far as possible, to the general knowledge of the Glacial 

 period, and to our knowledge of the relation of Hertfordshire to 

 the ice-action of that time, by recording all the boulders within 

 the county, or elsewhere, which come under their notice. I shall 

 be glad of any information thus obtained, which can be published 

 by this Society, and also included in the report of the Committee 

 of the British Association.
