It would appear to be $50,000 plus $125,000 if I'm reading that last note correctly.
In contrast, the $125,000 is included in the $850,000, as indicated by the breakdown in the table on page 9. Thus, though not stated explicitly, the report indicates that the $125,000 was sent to MIT (to fund Seth Lloyd's research but not into his personal bank account).
(At any rate, the fact that he accepted a gift of any amount, especially into his personal bank account, is very concerning. Sounds like currently he has been put on administrative leave and we'll see what happens after they're done deciding what to do.)
> The actions of a senior faculty member have raised new concerns. In keeping with MIT practice on faculty discipline, I have asked his department head to consider any appropriate action. In the meantime, in consultation with the provost, dean and department head, I have placed him on leave.
Also I think administrative leave is different from other types of leave, which are all also different from sabbatical.

> Eventually, in July 2016, Professor Lloyd affirmatively contacted Epstein by email to ask for funding to support his upcoming sabbatical. On June 1, 2017, Epstein emailed his accountant and Professor Lloyd: “send 125 k to mit for seth lloyd from gratitude.”
