Copy letter from Robert William Frederick Harrison, to Dr [Frank Watson] Dyson, Fellow of the Royal Society As [Arthur] Schuster must have told him, the enclosed letter about Transit of Venus '82 has been received [no enclosures]. Although Harrison was personally concerned with the business of that expedition, he did not see it through, and therefore his memory is not much of service. So far he has not been able to find any record of the precise definition of the points of observation beyond what is in the Blue Book Report, but he is making a further search here. 16 May 1914
