The first expansion effort was to Amherst College, Massachusetts, in 1847, but it only lasted about six months, at which time due to faculty opposition at Amherst, the parent chapter requested that it dissolve and return the constitution. However, a fragmentary document in the Yale library suggests that Beta was chartered in 1850 at Harvard University but lived a very short life due to a wave of puritanism. The chapter at Harvard was revived in 1911 as Beta Chapter but only survived about 20 years; the charter was withdrawn due to Harvard's anti-fraternity environment. When the Amherst College chapter was restored in 1854, it was designated as either Gamma or Delta Chapter. (a charter document found in Yale archives shows the latter, but "Bairds Manual" from its earliest editions and later records of the fraternity refer to it as Gamma.) When the chapter at Marietta College was chartered in 1860, it was given the Delta designation, despite the parent chapter being aware of this discrepancy.
