In the Laws of Harvard College of 1798, there is a section which reads:

Every person that has received and degree, may have a diploma signed by the Corporation, and sealed with the College seal, If he shall request it, and bring to the President a fair copy of the established form, written on vellum of parchment, and other things necessary thereunto, for which he shall pay to the President a fee not less than one dollar.

Since this provision of the College laws has never been specifically repealed, it might be presumed that should a member of a graduating class present to the President a diploma of the established form, which when the law was passed required a Latis text, the President would be obligated both to recognize it and sign it.
