THISBOOK was set on the Linotype in a face known by 

 the style " Modern No. 21." The " modern " part is a fam- 

 ily name. It indicates that Number 21 is a great-great- 

 grandchild of faces that were modern in 1800 new as 

 compared with the eighteenth-century types that preceded 

 them, such as Caslon. 



The book was composed, printed, and bound by The 

 Plimpton Press, Norwood, Massachusetts.
