And as it is not yet fully known what we have or what we want, The Directors have ordered us to write and request the Favour of you, if you have not laid out our Money not to purchase any Books till you hear from them which will be in a short Time. What you have purchased they desire you will please to forward by the first Opportunity. Among them we hope for the Pleasure of seeing your Works and Robertsons History of Charles 5th.9 We are, Sir with the greatest Esteem and Respect Your Obedient humble Servants.
