a number of short notes, and a tew articles dealing with paleonto- 

 logical and archaeological topics. His influence was largely personal. 

 At the time of his greatest activity in conchology — 1870 to 1895 — 

 he maintained a large correspondence, and was always ready to as- 

 sist students with information from the rich library of the Academy. 

 He was particularly helpful in naming specimens for conchologists 

 who had no access to large collections or libraries, much of his leisure 

 being given to this generous propaganda. Several species were named 

 in his honor, among them Donax fordi Conrad, Cerion fordi P. & V., 

 DrymcBUS fordi Pils. Pleurodonte fordiana Pils., Phasianella for- 

 diana Pils., and others. 



The portrait accompanying this sketch, is from his last photograph, 

 taken when Mr. Ford was about sixty years of age. 



He is survived by two sons William Henry and Albert W. Ford 

 and two daughters Parthenia Ford and Mrs. Charles W. Johnson.
