I think I had better warn you that, since sending in my synopsis to the Secretary, I have completely rewritten my lecture—so that, in my case, the relation between promise and fulfilment is likely to be strained. In this connection you may recall the words of Coleridge in introducing his lectures on Shakespeare:—

Unaccustomed to address such an audience, and having lost by a long interval of confinement the advantages of my former short schooling, I had miscalculated in my last lecture the proportion of my matter to my time, and by bad economy and unskilful management, the several heads of my discourse failed in making the entire performance correspond with the promise publicly circulated in the weekly annunciation of the subjects to be treated.
