Copy letter from an unknown correspondent, to Messrs Dulau & Company 'Dr Lendenfeld complains that the copies of the monograph (which was inclosed in parcels delivered to your care Aug. [August] 22) have not yet been received by the gentlemen to whom they were sent, & that complaints & enquiries are pouring in upon him. If these are still lying at your office or the office of your agents I think it is an unreasonable delay, & I should be glad if you would see that they are released as soon as possible'. 18 September 1889
