Since you're interested in the language of by-laws:

"Male white students in any university or college having a chapter of the Delta Chi Fraternity, who are pursuing studies in, law, liberal arts, journalism, commerce, or finance, by whatever name such courses may be known, who have paid the "XX" per capita tax, Delta Chi Quarterly tax and one dollar for the Fraternity shingle, are eligible for membership in the Delta Chi Fraternity; provided such persons are not candidates for any degree in any subject other than those above named; and provided further that a chapter having 25 per cent of its active members in law or bona-fide pre-legal coursed, may initiate students into the Fraternity who are not eligible as above, to the extent that such members shall not, at any time exceed 25 per cent of the entire membership of the chapter." (1921)

This essentially made Delta Chi a generally fraternity, in 1922 they cut out the course limitations officially making us a general social fraternity: "Male white students in any university or college having a chapter of the Delta Chi Fraternity."

The "white" restriction was eliminated in 1954.
