TOPICS WITH CROSS-REFERENCES 



Reference denotes not necessarily equivalence , but illustration or suggestion , sometimes contrast or even 

 antithesis. Cross-references may often be followed out still more fully by looking up in the General Index also the 

 topics referred to. Particular items, as the names of animals, instruments, etc., are to be sought in the General 

 Index, and names of persons, places, etc., in the Index of Proper Names, or of Authors and Publishers.
