I found the first five chapters practically completed, while it has not been difficult, as a rule, to discover from his copious notes what his intentions were as to the details of the following chapters. I have been greatly aided by the assistance of Dr. Adolf Meyer and of Dr. Kirby. The latter has been good enough to read the entire manuscript, making invaluable suggestions and criticisms. John T.
