OTHER REFERENCES AND SOURCES 
HE following list contains all the works referred to in 
ale the foregoing text, and also a number of other publica- 
tions upon which I have relied for information—or 
which I have had to read—but to which no specific allusion is 
made elsewhere. Annotations are added where they appear 
needful.
