PREFACE 



I SHOULD scarcely venture to publish the following 

 memoirs, which were originally written for my family, 

 had it not been for the persuasion of several friends 

 whose opinion I value highly. Amongst those who 

 have thus given me help and advice I must mention 

 the names of Dr. T. E. Thorpe, C.B., F.R.S., and 

 Dr. A. W. Ward, the Master of Peterhouse. To 

 these, and other friends, I offer my best thanks.
