Copy letter from Robert William Frederick Harrison, to Professor Karl Pearson, Fellow of the Royal Society In reply to Pearson's letter sends a copy of remarks extracted from reports of referees on Pearson's paper on barometric frequency, together with Pearson's own remarks on these [no enclosures]. Is having a search made for the diagrams missing from the set which Pearson lately exhibited at the Soiree. Will send them at once if found but is doubtful of success. 15 October 1897
