The constitutional requirement of such an address resulted from the 1850 convention and was later incorporated as Art. II sec. 18:
"He shall from time to time inform the Legislature of the condition of the State, and recommend to their consideration such measures as he may judge necessary and expedient."
Today, it is Section 19, and the language is the same. In the 1864 Constitution, the requirement was Section 20; the only difference in language was the reference to the "General Assembly" rather than the "Legislature."
From the Senate Journal (Nov. 1796 session, page 4/AOMOL vol. 105, page 4):

The Senate Journal from the 1920 session indicates that Gov. Harrington's message of January 7, was sent via the Secretary of the State, as the chain of events are as follows:
The comment of the discharge is puzzling, as there is no mention of Harrington's appearance. Perhaps he did make a very brief appearance, as it was the opening day of Session, as well as the day that election results were certified.
