BETWEEN THE TYNE AND THE WANSBECK I09 



T. H. Hitch, Esq.), for leave readily granted of access to their 

 grounds ; and to my colleague, Dr. Woolacott, for the loan of 

 several maps of the eastern part of the area, in which he has 

 carefully recorded the results of borings and sinkings, and also 

 for his verification in the field of many of my observations. 



I am especially indebted to Professor Lebour for his 

 constant interest in the work, and for much valuable 

 criticism which he has been ever ready to bestow upon it.
