William Dwight Whitney was an editor on Webster's Dictionary and a founding member of the American Philological Association. Principally a scholar of Sanskrit, he was a known expert on comparative linguistics. In this piece he reviews the Vedic syntax of Delbruck, who is thought of by many as the founder of the study of comparative linguistics and the first to open work on the nature of Indo-European language. This review of one brilliant man's work by another brilliant man is fascinating reading to any inquiring mind, but is of particular interest to linguists with an interest in the origin of their field of study.
