‘Two months after Sir John and I were married we travelled to Cambridge to seek a cure for Sir John’s melancholie from Dr Richard Blackswan, a very famose Physician. We took with us a little cristall flask that had some of Sir John’s water in it. Dr Blackswann went into a little closet behind a curtain of blacke velvet and prayed upon his knees. The Angell Raphael then appearing in the closet (as commonly happens when ever this doctor prays) peer’d into Sir John’s urine. Dr Blackswann told us that the Angell Raphael knew straightway from the colour of it (reddish as if there waz bloude in it) that the cause of Sir John’s extreame Want of Spirits was a lack of Learned Conversation.’
